1. Description
The Sharp IrDA Control Infrared Transceiver provides
the wireless interface between logic and IR signals for
through-air, serial, half-duplex IrDA Control data links
and is designed to satisfy the IrDA Control Physical
Layer Specifications for Peripheral Type 2.
The GP2W2002YK is a low power operatable integrated
infrared transceiver that contains an IRLED, a LED
driver circuit, a PIN photodiode, an excellent sensitivity
receiver, and an envelope detector. The transceiver also
contains some additional functions, such as shut down
and sensitivity recovery for low current consumption and
longer communication distance.
