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 (2.4115.2 Kbps, 1 meter minimum), LocalTalk™, and Sharp ASK™ modes, the ZHX1000 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.
