Description

The HSDL-1000 serial infrared module performs low cost, low power, point-to-point, through the air data transfer in a serial, halfduplex mode.

The HSDL-1000 has been designed to the IrDA (Infrared Data Association) Physical Layer Specifications. The module is designed to operate from 0 to 1 meter at a data rate of 115.2 Kbd per second at a 30° viewing angle.

The HSDL-1000 contains a high speed, high efficiency TS AlGaAs 875 nm LED, a PIN Silicon photodiode and an integrated circuit. The IC contains an LED driver, amplifiers and a quantizer.

The HSDL-1000 is designed to interface directly with selected I/O chips that incorporate logic which performs pulse width modulation/ demodulation.
