ZHX1000
SIR Transceiver

Description
The ZiLOG ZHX1000 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 personal
data assistants (PDAs). Designed to support the SIR (serial infrared) Infrared
Data Association (IrDA) Data standard (2.4–115.2 Kbps, 1 meter minimum),
LocalTalk™, and Sharp ASK™ modes, the transceiver combines an infrared emitting diode (IRED), a PIN photodiode detector, a digital AC coupled IRED driver,
and a receiver/decoder with noise discrimination circuitry in a single, miniature
package.
The ZiLOG ZHX1000 SIR transceiver provides an efficient implementation of the
IrDA-Data standard in a small footprint format. Application circuit space is also
minimized, as only two external resistors and one capacitor are needed to complete the IrDA transceiver solution. The ZHX1000 SIR transceiver meets the
IEC825-Class 1 Eye Safety limits.
A full external shield minimizes radio frequency interference (RFI) and electromagnetic interference (EMI) problems.

VCC Positive Supply
(Power)
Connect to positive power supply (2.4–5.5 V).
Place a .33-µF ceramic bypass capacitor (optional) 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.

This input has an internal pull-down resistor that is disabled (open-circuited)
during shutdown. TXD has integrated digital AC coupling that prevents inadvertent
“always on” IREDs; 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 1 µA. Module shutdown current might 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 to minimize shutdown
current to nanoamp levels. 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 LEDA
through a current limiting resistor. Current to the IRED must be limited to a maximum of 500 mA (20% duty cycle maximum). The maximum voltage on this pad is
limited to +5.5 volts or VCC.

Moisture Prevention Guidelines
In order to avoid moisture absorption during transportation and storage, ZHX1000
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 prevent moisture entry.
Please read the label on the aluminum bag for indicator instructions.
