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.
