operate from 0 to 1 meter at a
data rate of 115.2 Kbd per second
at a 30擄 viewing angle.
The HSDL-1000 contains a high
speed, high efficiency TS AlGaAs
875 nm LED, a PIN Silicon photo-
diode and an integrated circuit.
The IC contains an LED driver,
amplifiers and a quantizer.
The module is designed to inter-
face directly with selected I/O
chips that incorporate logic which
performs pulse width modulation/
demodulation.
