Description
The ZILOG ZHX1810 is a low-profile version of Zilog’s popular ZHX1010
1-meter transceiver. The transceiver is mechanically enhanced for ultra compact, power-
conscious portable produ cts, such as mobile phones, portable printers, handheld com-
puters, and personal data assistants (PDAs). Designed to operate using the IrDA-Data
mode, the transceiver combines an infrared emitting diode (IRED) emitter, a PIN photo-
diode detector, a digital AC coupled LED driver, and a receiver/decoder in a single
package.
The ZILOG ZHX1810 provides an efficient implementation of the SIR standard in a
small-outline footprint format. Application circuit space is also minimized, as only three
components are required.
ZHX1810 also features an independently controlled shutdown that minimizes current
draw to a maximum of 1 A.

Pin Descriptions
The ZHX1810 transceiver uses the pins listed in Table 1. The pins are described in this
section.
LEDA LED Driver Anode
(Power)
This output is connected to the LED anode. Current to the LED is sourced through an
external resistor.

TXD Transmit Data
(Input, active high)
This CMOS input is used to transmit serial data. This input has an internal pull-down
resistor that is disabled (open-circuited) during shutdown.
RXD/Receive Data
(Output, active low)
This output indicates received serial data. It is a tri-state, slew rate controlled CMOS
output (tri-stated during shutdown) driver capable of driving a standard CMOS load. No
external resistor is required.
SD Shutdown
(Input, active high)
This input is used to place the integrated circuit into shutdown mode. Module shutdown
current is influenced by the choice of capacitor used from VCC to ground.
VCC Positive Supply
(Power)
Connect to positive power supply (2.4–5.5 V). Filter with a 0.33-F ceramic bypass
capacitor and terminating resistor as close as possible to the VCC pin.
GND Ground
(Power)
Connect to ground of the power supply. A solid grou nd plane is recommended for
proper operation.
TAB
(Shield)
The Shield tab must be soldered to the ground plane.

that have been unpacked, but will not be soldered within 72 hours, must be stored in a
desiccator.
Baking
Parts that have been stored over 12 months or unpack ed over 72 hours must be ba ked
under the following guidelines.
Reels
60 °C for 48 hours or more
Loose Parts

Moisture-Proof Packing
In order to avoid moisture absorption during transportation and storage, ZHX1810 reels
are packed in aluminum envelopes (see Figure 8) that contain a desiccant with a humid-
ity indicator. While this packaging is an impediment to moisture absorption, it is by no
means abso lute, and no warranty is implied. The user should store these parts in a con-
trolled environment to prevent moisture entry. Please read the label on the aluminum
bag for indicator instructions.
