Description:
The HSDL-1000 serial infrared
module performs low cost, low
power, point-to-point, through the
air data transfer in a serial, half-
duplex mode.
• Excellent EMI Immunity
(> 10 V/m)
The module is designed to inter-
face directly with selected I/O
chips that incorporate logic which
performs pulse width modulation/
demodulation.
The module has been designed to
