DESCRIPTION
These products are miniaturized receivers for low speed
infrared data transmission. A PIN diode and a preamplifier
are assembled on a lead frame, the epoxy package contains
an IR filter.
The demodulated output can be directly connected to a
UART or a microprocessor. The TSDP34138 may be used
for continuous reception of data according to RS-232 at
4800 bps in noise free environments. Higher data rate
RS-232 may require data monitoring of gain levels. Non
RS-232 codings may be used to achieve continuous
average data rates up to 7800 bps in noisy ambients.
This component has not been qualified according to
automotive specifications.
