Description

Clare CPC5610 and CPC5611 LITELINKs are silicon

data access arrangement (DAA) ICs used in data and

v oice communication applications to make connec-

tions to the pub l ic switched telephone network

(PSTN). LITELINK uses on-chip opt ical component s

and a few inexpensive external components to form a

complete v oice or high- speed d ata teleph one line

interface.

LITELINK eliminates the need for the large isolation

transformers or capacitors as used in other DAA con-

figurations . It incorporates the required high-voltage

isolation barrier in the surface-mount SOIC package.

The CPC5610 (half-wave ring detect) and CPC56 11

(full-wave ring detect) build upon Clare’s existing

LITELINK line, wit h improved performance and 3.3 V

operation.

2. Application Circuits

LITELINK can be used with telephone networks world-

wide. Some pub lic telephone netw orks, notab ly in

North America and Japan require resistive line temri-

nation. Other telephon e netw orks in Europe and else-

where require reactive line termination.

The application circuits belo w address both line termi-

nation models. The rea ctive termination application

circuit (see Section 2.2 on page 8) describes a TBR-21

implementation. This circuit can be adapted easily for

other reactiv e termination needs. Worldwide applica-

tion of LITELINK is described more fully in Clare appli-

cation note AN-147, Worldwide Application of LITELINK.

3. Using LITELINK

As a full-featured telephone line interface, LITELI NK

performs the following functions:

•DC termination

•A C impedance control

•V/I slope control

•2-wire to 4-wire conversion (hybrid)

•Current limiting

•Ring detection

•Caller ID signal reception

•Switch hook

LITELINK can accommodate specific application f ea-

tures without sacrificing basic functionality and perfor-

mance. Application features include, but are not

limited to:

•High gain (+3 dBm) oper ation

•Pulse dialing

•Ground start

•Loop start

•Parallel telephone off-hook detection (911 feature)

•Battery reversal

•Line presence

•W orld-wide progr ammab le oper ation

This section of the data sheet describes LITELINK

operation in st andard configuration for usual oper a-

tion. Clare off ers addit ional applicat ion inf ormation on-

line (see Section 5 on page 14). These include informa-

tion on the following topics:

•Circuit isolation considerations

•Optimizing LITELINK performance

•Data Access Arrangement architect ure

•LITELINK circuit descriptions

•Surge protection

•EMI considerations

Other specific application materials are also refer-

enced in this section as appropriate.

3.1 Switch Hook Control (On-hook

and Off-hook States)

LITELINK operates in one of two conditions, on-hook

and off-hook. In the on -hook condition t he te lephone

line is available for calls. In the off-hook condition the

telephone line is engaged. Use the OH control input to

place LITELINK in one of these two states. With OH

high, LITELINK is on-hook and ready to make or

receive a call. The snoop circuit is enab led. Assert OH

low to place LITELI NK in th e off -hook st ate. In the off-

hook state, loop current flows through LITELINK and

the system is answering or placing a call.

3.2 On-hook Operation

The LITELINK application circuit leakage current is

less than 10 µA with 100 V across ring and tip, equiv a-

lent to greater t han 10 MΩ on-hook resist ance .

3.2.1 Ring Signal Detection via the Snoop

Circuit

In the on-hook state (OH and CID not asserted), an

internal multiplexer turns on the snoop circuit. This cir-

cuit monitors the telephone line for two conditions; an

incoming ring signal, and caller ID data bursts.

Refer to the application schematic diagram (see Figure

3 on page 6). C7 (CSNP-) and C8 (CSNP+) provide a

high-v oltage isolation barrier between the telephone

line and SNP- and SNP+ on the LITELI NK while cou-

pling A C signals to the snoop amplifier. The snoop cir-

cuit “snoops” the telep hone line cont inuously while

dra w ing no current. I n the LITELINK, ringing signals

are compared to a threshold. The comparator output

f orms the RING signal output from LITELINK. This sig-

nal must be qualified by the host system as a valid

ringing signal. A low level on RING indicates that the

LITELINK ring signal threshold has been exceeded.

F or the CPC5610 (wit h t he half-wave ring detector),

the frequency of the RING output f ollo w s the fre-

quency of the ringing signal from the central office

(CO), typically 20 Hz. The RING output of t he

CPC5611 (with the full-wa ve ring detector) is twice the

ringing signal frequency.

Hysteresis is employed in the LITELINK ring detector

circuit to provide noise imm unity. The setup of the ring

detector comparator causes RING output pulses t o

remain low for most of the ringing signal half-cycle.

The RING output returns high f or the entire negativ e

half-cycle of the ringing signal for the CPC5610. For

the CPC5611, the RING output returns high for a short

period near the zero-crossing of the ringing signal

bef o re re turning low during the positive half -cycle . For

both the CPC5610 and CPC5611, t he RING output

remains high between ringing signal b ursts.

The ring detection threshold depends on the v alues of

R3 (RSNPD), R6 (RSNP-), R7 (RSNP+), C7 ( CSNP-), and

C8 (CSNP+). The value s for these components sho wn

in the typical application circuits are recommended f or

typical operation. The ring detection threshold can be

changed according to the following formula:

Clare Application Note AN-117 Customize Caller ID Gain

and Ring Detect Voltage Threshold is a spreadsheet for

trying different component values in this circuit.

Changing the ring detection threshold will also change

the caller ID gain and the timing of the polarity rev ersal

detection pulse, if used.

3.2.2 Polarity Reversal Detection with

CPC5611

The full-wave ring detector in the CPC5611 makes it

possible t o detect tip and ring polarity reversal using

the RING output. When the polarity of tip and ring

re verses, a pulse on RING indicates t he ev ent. Your

host system must be able to discriminate this single

pulse of appro ximately 1 msec (using the recom-

mended snoop circuit e xternal components) from a

v alid ringing signal.

3.2.3 On-hook Caller ID Signal Processing

On-hook caller ID (CID) signals ar e processe d by

LITELINK b y coupling the CI D data burst through the

snoop circuit to the LITELINK RX output s under con-

trol of the CID pin. In North America, CID data signals

are typically sent betw een the first and second ringing

signal.

Figure 5. On-hook Caller ID Signal Timing in

North America for CPC5610 (with Half-

wave Ring Detect)

In North American applications, follow these steps to

receiv e on- hook caller ID data via t he LITELINK RX

outputs:

1. Detect the first ringing signal outputs on RING.

2. Assert CID low.

3. Process the CID data from the RX outputs.

4. De-assert CID (high or floating).

Note: Taking LITELINK off-hook ( via the OH pin) dis-

connects the snoop path from both the receive outputs

and the RING output, regardless of the state of the

CID pin.

CID gain from tip and ring to RX+ and RX- is deter-

mined by:

where ƒ is the frequency of the CID data signal.

The recommended components in the application cir-

cuit yield a gain 0.27 dB at 200 Hz. Clare App licat ion

Note AN-117 Customize Caller ID Gain and Ring Detect

Voltage Threshold is a spreadsheet for trying different

component values in this circuit. Changing the CID

gain will also change the ring detection threshold and

the timing of the polarity reversal detection pulse, if

used.

F or single- ended snoop circuit out put of 0 dBm, set

the total resistance across the series resistors (R6/

R44 and R7/R45) to 1.4 MΩ.

3.3 Off-Hook Operation

3.3.1 Receive Signal Path

Signals to and from the telephone n etwork appear on

the tip and ring connections of the application circuit.

Receive signals ar e e xtracted from transmit signals b y

the LITELINK two-wire to four-wire hybrid. Next, the

receiv e signa l is converted to infrared light by the

receiv e phot odiode amplif ier and receive path LED.

The intensity of the light is modulated by the receiv e

signal and coupled across the electrical isolation bar-

rier by a reflective dome.

On the host equipment side of t he barrier, the receiv e

signal is converted by a photod iode int o a photocu r-

rent. The photocurrent, a linear representation of the

receive signal, is amplified and con v erted to a diff eren-

tial v oltage o utput on RX+ and RX-.

Variations in gain are controlled to within ±1 dB by an

on-chip automatic gain control (AGC) circuit, which

sets the output of the photoamplifier to unity gain.

To accommodate single-supply oper ation, LITELINK

includes a small DC bias on the RX outputs of 1.0

Vdc. Most applications should AC couple the RX out-

puts as shown in Figure 6.

LITELINK ma y be used for diff erential or single-ended

output as shown in Figure 6. Single-end ed use will

produce 6 dB less signal output amplitude. Do not

e xceed 0 dBm into 600 Ω (2.2 VP-P) signal input.

Figure 6. Differential and Single-ended Receive

Path Connections to LITELINK

3.3.2 Transmit Signal Path

Connect transmit signals from t he host equipment to

the TX+ and TX- pins of LITELINK. Do not exceed a

signal level of 0 dBm in 600 Ω (or 2.2 VP-P). Differen-

tial transmit signals are converted to single-ended sig-

nals in LITELINK. The signal is coupled to the transmit

photodiode amplifier in a similar manner to the receiv e

path.

The output of the photodiode amplif ier is coupled t o a

v olt age-to-curr ent converter via a transconductance

stage where the transmit signa l modulat es t he tele-

phone line loop current. As in the receive path, gain is

set to unity automatically, limiting insertion loss to 0,

±1 dB.

Path Connections to LITELINK

3.4 DC Characteristics

The CPC5610 and CPC5611 are designed for world-

wide application regarding DC characteristics, includ-

ing use under the requirements of TBR-21. The ZDC,

DCS1, and DCS2 pins control the VI slope char act er-

istics of LITELINK. Selecting appropriate resistor val-

ues f or RZDC (R16) and RDCS (R15 ) in the provided

application circuits assure compliance with DC

requirements.

3.4.1 Resistive Termination Applications

LITELINK includes a telephone line current limit fea-

ture that is selectable by selecting th e desired value

for RZDC (R16) using the following formula:

Clare recommends using 8.2 Ω for RZDC in North

America and Japan, limiting telepho ne line current t o

133 mA.

3.4.2 Reactive Termination Applications

TBR-21 sets the telephone line current limit at 60 mA.

To meet this requirement, set R ZDC (R16) to 22. 1 Ω.

tive LITELINK Designs f or information on FET heat sink-

3.5 AC Characteristics

3.5.1 Resistive Termination Applications

North American and Japanese telephone line AC ter-

mination requirements are met with a re sistive 600 Ω

AC termination. Receive termination is applied to the

LITELINK ZNT pin (pin 29) as a 301 Ω resistor, RZNT

(R10). A 150 Ω resistor, R18 (RZTX), applied to the

LITELINK ZTX pin (pin 30) sets the corr ect transmit

gain and impedance.

3.5.2 Reactive Termination Applications

Many areas use a single-pole complex impedance to

model the telephone netw ork transmission line char-

acteristic impedance as shown in the tab le below.

Matching a comple x impedance requires the use of

comple x networks on ZNT and ZTX. In order to

accommodate high pow er levels , it is necessary to

modify the transmit and receiv e gain char acteristics of

your LITELI NK implementation. The complex network

on the ZTX pin increases tr ansmit gain by 7 dB. A 7

dB pad may be inserted bef ore t he TX+ and TX- pins

to provide overall unity gain. Similarly, with a complex

network, the ratio of R12 ( RNTF) and R13 (RNTS) must

be modified from 1:1 to 1:.287, which introduces a 7

dB loss in the receive path from tip and ring to ZNT.

4. Regulatory Information

LITELINK can be used to build products that comply

with the requirements of TIA/EIA/IS-968 (formerly

FCC part 68), FCC part 15B, TBR- 21, EN60950,

7.3.1 Moisture Reflow Sensitivity

Clare has characterized the moist ure reflow sensitivity

of LITELINK using IPC/JEDEC standar d J-STD-020A.

Moisture uptake from atmosphe ric humidity occurs by

diffusion. During the solder reflow process, in which

the component is attached to the PCB, the whole body

of the component is exposed to high process temper a-

tures. The combination of moist ure upt ake and high

reflow soldering temper atu res may lead to moisture

induced delamination and crac king of the component.

To prevent this, this component must be handled in

accordance with IPC/JEDEC standard J-STD-020A

per the labeled moisture sensitivity le vel (MSL), le vel

7.3.2 Reflow Profile

The maximum ramp rates, dwell times, and tempera-

tures of the assemb ly reflo w profile should n ot e xceed

those specified in IPC/JEDEC standard J-STD-020A,

which were used to determine the moisture sensitivity

le vel of this component.
