Description
The ZiLOG ZHX1000 SIR transceiver is the ideal choice for applications
in today’s ultra-compact and power-conscious port able 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 discrimi nation 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 ci rcuit 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.

TXD Transmit Data
(Input, active high)
This CMOS input is used to transmit serial data.
PS015004-0702 Do not use in new designs
This input has an internal pull-down resistor that is disabled (open-cir cuited)
during shutdown. TXD has integrat ed digital AC co upling that prevent s inadvertent
“always on” IREDs; therefore, no external AC coupling components are required
for input signals between GND and V
RXD Receive Data
(Output, active low).
This output indicates received serial data. It is a tri-state, slew rate controll ed
CMOS output (tri-stated during shutdown) driver capable of driving a st andard
CMOS or LSTTL load. No external resistor is required.

(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 curren t might be limit ed
by the choice of capacitor used from V
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 vol tage on this pad is

To avoid moisture absorption, ZHX1000 reels must remain in the original,
unopened moisture-proof packing. Parts must be soldered within 48 h ours after
unpacking. Reels that have been unpack ed, but will not be soldered within 48
hours, must be stored in a desiccator.
Baking
Parts that have been stored over 12 months or unpacked over 48 hours must 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
PS015004-0702 Do not use in new designs
Moisture Prevention Guidelines
In order to avoid moisture absor ption du ring transpo rtat ion and sto rage, 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.
