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.
