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), LocalTalkTM, and Sharp ASKTM 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.
Features * * * * * * *
Compliant to IrDA SIR Specifications (2.4-115.2 Kbps, 1 meter minimum) Wide supply voltage range, 2.4 to 5.5 V Low power, 90 A (typical) at 3 V Full-shield option: 9.9 mm long x 4.2 mm wide x 4.0 mm high Two external components: one resistor and one capacitor Extended operating temperature range (-30 C to +85 C) Meets the IEC 825-1 Class 1 Eye Safety Specifications

Pin Descriptions
The ZHX1000 SIR transceiver uses the pins listed in Table 1. The pins are described in this section.
Table 1. Pin Out for the ZHX1000 SIR Transceiver Pin 1 2 3 4 5 6 -- Name LEDA TXD RXD SD VCC GND TAB Function IRED anode Transmitter input Receiver output Enables shutdown mode Supply voltage Ground Shield ground I/O -- I O I -- -- --
VCC Positive Supply
(Power) Connect to positive power supply (2.4-5.5 V). Place a .33-F 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 A. 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.

ZHX1000 Packing, Storage, and Baking Recommendations
Follow these recommendations to maintain the performance of the ZHX1000 SIR transceiver.
Storage
To avoid moisture absorption, ZHX1000 reels must remain in the original, unopened moisture-proof packing. Parts must be soldered within 48 hours after unpacking. Reels that have been unpacked, 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

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.
