4 Mb/s Infrared Data Transceiver
Preliminary
Features
• IrDA, HP-SIR, Local Talk and Sharp ASK
• Ultracompact package:
• H 4.0 mm x D 4.8 mm x L 9.8 mm
• Data rates from 9.6 Kbit/s to 4 Mbit/s
• Supply voltage 2.7 V to 5.25 V
• Power Shutdown mode (<100 nA)
• Low power consumption
– 1.7 mA (typ) @ 2.7 V
– 3.2 mA (typ) @ 5.0 V
• Zero external resistors required
Description
Responding to the volumetric constraints of today’s
ultra-compact and power conscious portable prod-
ucts, Vishay has developed the next generation in
infrared wireless communication transceivers. The
transceiver has been designed to support up to 4
Mbit/s IrDA, HP-SIR, Local Talk and Sharp
ASK modes. The device combines an LED, photo-
diode, LED driver and a fully differential receiver into a
single integrated package.
