Description
The ZiLOG ZHX1010 SIR transceiver is the ideal choice for applications
in today’s ultra-compact and power-conscious portable products, such as mobile
phones, digital cameras , portable printers, handheld computers, or persona l
data assistants (PDA). Designed to support the SIR (serial inf rared) Infrared
Data Association (IrDA) Data standar d (2.4–115.2 Kbps, 1 meter minimum),
LocalTalk™, and Sharp ASK™ modes, the transceiver combin es an infrared emit-
ting diode (IRED), a PIN photodiode detector, a digital AC coupled IRED driver,
and a receive r/ decoder with noise discrimination circuitry in a single, miniature
package.
The ZiLOG ZHX1010 SIR transceiver provides an efficient implementation of the
IrDA-Data standar d in a small footprint format. Applicati on circuit space is also
minimized, as only two external resistors and one capacitor are needed to com-
plete the IrDA t ransceiver soluti on. The ZHX1010 SIR transceiver meets the
IEC825-Class 1 Eye Safet y li m its.
An external shield minimizes radio frequency interference (RFI) and electromag-
netic interference (EMI) problems.

•
Extended operating temperature range (–30 °C to +85 °C)
•
Meets the IEC 825-1 Class 1 Eye Safety Specifications

Pin Descriptions
The ZHX1010 SIR transceiver uses the pins listed in Table 1. The pins are
described in this section.
VCC Positive Supply
(Power)
Connect to positive power supply (2.4–5.5 V).
Place a .33-µF ceramic bypass cap acitor (opti onal) as close as possible to the
VCC pin.
GND Ground
(Power)
Connect to ground of the power suppl y. A solid ground pl ane is recommended for
proper operation.
TAB
(Shield)
The Shield tab must be soldered to the ground plane.
TXD Transm it Data
(Input, active high)
This CMOS input is used to transmit serial data.

This input has an internal pull-down resistor that i s disabled (open-circuited)
during shut down. TXD has integrated di gital AC coupling t hat prevents i nadvertent
“always on” IREDs; therefore, no external AC coupling component s are required
for input signals between GND and VCC.
RXD Receive Data
(Output, active low).
This output indicates received serial dat a. It is a tri-state, slew rate controlled
CMOS output (tri-stated during shutdown) driver cap able of driving a standard
CMOS or LSTTL load. No external resistor is required.
SD Shutdown
(Input, active high)
This input is used to place the integrated circuit into shutdown mode. Maximum
current draw in shut down mode is 1 µA. Module shut down current mi ght be limited
by the choice of capacitor used from VCC to ground. A 0.1-mF ceramic capacitor
with very high DC impedance (1–10 G ohm) is required t o minimi ze shutdown
current to nanoamp level s. During shutdown, the output is tri-stated, and the TXD
input pull-down resistor is disabled (open circuited).
LEDA IRED Driver Anode
(Output, active low).
This output is internally connected to the IRED anode and is connected to LE DA
through a current limiting resistor. Current to the IRED must be limited to a maxi-
mum of 500 mA (20% duty cycle maximum). The maxi mum voltage on this p ad is
limited to +5 .5 v ol ts or VCC.

Moisture Prevention Guidelines
In order t o avoid mois ture absorpt ion during tr ansport ation an d storage, ZHX1010
reels are packed in aluminum envelopes (see Figure 6) that contain a desiccant
with a humidity indicator. While this packaging is an impediment to moisture
absorption, it is by no means absolute, and no warranty is implied. The user
should store these parts in a controlled environment to pre vent moisture entry.
Please read the label on the aluminum bag for indicator instructions.
