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 1.
The GP2W2001YK 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.
