ZHX1200
Low-Power SIR (IrMC) Transceiver
1
Description
The ZiLOG ZHX1200 is the transceiver of choice for mobile communication applications in today’s ultra compact, power-conscious, portable products, such as
mobile phones, pagers, or personal data assistants (PDAs). Specifically designed
to support Infrared Data Association (IrDA) IrMC low-power SIR (serial infrared)
mode, the transceiver combines an infrared emitting diode (IRED) emitter, a PIN
photodiode detector, a digital AC-coupled LED driver, and a receiver/decoder in a
single, miniature package.
The ZiLOG ZHX1200 provides an efficient implementation of the low-power SIR
standard in a small footprint format. Application circuit space is also minimized, as
only one capacitor is required to complete the solution.

VCC Positive Supply
(Power)
Connect to positive power supply (2.7–3.6 V).
Place a 0.33-µF ceramic bypass capacitor as close as possible to the VCC pin.
GND Ground
(Power)
Connect to ground of the power supply. A solid ground plane is recommended for
proper operation.
TAB
(Shield)
The Shield tab must be soldered to the ground plane.
TXD Transmit Data
(Input, active high)
This CMOS input is used to transmit serial data.
PS007107-1101
ZHX1200
Low-Power SIR (IrMC) Transceiver

This input has an internal pull-down resistor that is disabled (open-circuited)
during shutdown. TXD has integrated digital AC coupling; therefore, no external
AC-coupling components are required for input signals between GND and VCC.
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 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 shutdown mode is 0.2 µA. Module shutdown current might be limited by the choice of capacitor used from VCC1 to ground.
LEDA IRED Driver Anode
(Power)
This output is internally connected to the LED anode and is connected to the supply voltage. Current to the LED must be limited to a maximum of 50 mA (20% duty
cycle maximum). The voltage range on this pad is 2.7–3.6 volts.

Packing, Storing, and Baking Recommendations
Follow these recommendations to maintain the performance of the ZHX1200
transceiver.
Moisture Prevention Guidelines
In order to avoid moisture absorption during transportation and storage, ZHX1200
reels are packed in aluminum envelopes (see Figure 14) 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 prevent moisture entry.
Please read the label on the aluminum bag for indicator instructions.
