SHARP IrDA Control Infrared Transceiver

IrDA Control Infrared Transceiver (for Peripheral Type 1)
GP2W2001YK

Technical Data

MEMBER IrDA

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.

10. RESET Function

The “RESET” terminal is used to recover the receiver sensitivity to its maximum level. Since Sharp IrDA Control
Infra red Tra nsc eiver h as a built-in cap abilit y to adj us t t he r eceiving sensitivity, as a result, a very weak IR signals may
not be correctly received just after receiving a very strong IR signals.
Following figure shows an example of “RESET” signal in order to recover the Sharp IrDA Control Infrared
Transceiver’s receiving sensitivity to its receiving sensitivity to its maximum level:

(NOTES)
This pinout is an Active Low terminal, and stays HIGH level when it is OPEN. The Low Level Pulse for the period of
> 13µsec enables this function to work. This >

13µsec input must be pulsed within the period of Gap time in order for
the transceiver to have receiver sensitivity recovery. The timing for this “RESET” pulse should be adjusted at
controller side.
