Description
The ZILOG ZHX1201 for mobile phones, pagers, and PDAs is a small, low power, and high functionality transceiver. ZiLOG's low-power CMOS technology allows the transceiver to receive an IrDA communication at a typical current of 100 A. The UltraSlim form factor (8 mm long x 3 mm wide x 2.5 mm high) allows placement in many small devices (see Figure 1). Application circuit space is also minimized because only one external component is required.
Figure 1. UltraSlim Form
The ZHX1201 is designed to support IrDA-Data SIR mode, which at 115 Kbits/s provides the capability for the user to share phone numbers, addresses, and notes as well as linking a PC to the internet via a mobile telephone. The transceiver combines an IRED emitter, a PIN photodiode, and a unique driver/control ASIC in a single package, as shown in Figure 2.
Figure 2. ZHX1201 Block Diagram
The ZILOG ZHX1201 also features a shutdown control that minimizes current draw to 0.1 A typical.

GND Ground
(Power) Connect to ground of the power supply. A solid ground plane is recommended for proper operation.
SD Shutdown
(Input, active high) This input is used to place the IC into a shutdown mode. TxD needs to be driven low to achieve low shutdown current and held low during the transition from shutdown to active to ensure that the circuitry is properly set to communicate.
RxD Receive Data
(Output, active low) This output provides 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 LS series TTL load. No external resistor is required.
TxD Transmit Data
(Input, active high) This CMOS input is used to transmit serial data and has an internal pull-down resistor that is disabled (open-circuited) during shutdown. With integrated digital AC coupling, no external components are required for input signals between GND and VCC.
LEDA LED Driver
(Power) This output is internally connected to the LED anode and contains an internal current source. The voltage range on this pad is 2.4-4.2 volts.
TAB Shield Connection
The shield tab must be soldered to ground for proper operation.

Moisture Prevention Guidelines
To avoid moisture absorption during transportation and storage, ZHX1201 reels are packed in aluminum envelopes (see Figure 7) 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 must store these parts in a controlled environment to prevent moisture entry. Please read the label on the aluminum bag for indicator instructions.
Figure 7. ZHX1201 Packaging
Baking
It is recommended that parts that have been stored over 12 months or unpacked over 72 hours be baked under the following guidelines. Reels 60 C for 48 hours or more Loose Parts
* * *
100 C for 4 hours or more or 125 C for 2 hours or more or 150 C for 1 hour or more
