Description
The HSDL-1001 infrared
transceiver provides the interface
between logic and IR signals for
through-air, serial, half-duplex IR
data links and is designed to
satisfy the IrDA Physical Layer
Specification for data rates up to
115 Kb/s.
The HSDL-1001 contains a high
speed, high efficiency TS AlGaAs
875 nm LED, a silicon PIN
photodiode and a bipolar, silicon
HSDL-1001
integrated circuit. The IC contains
an LED driver, amplifiers and
a quantizer.
The shutdown function permits
operating the receiver in a
low current mode to minimize
battery drain.
Applications for the HSDL-1001
include notebook PCs, telephones,
pagers, printers, cameras, and
industrial handheld devices.

3. RXD Low is a pulsed response. The condition is maintained for a duration dependent
on the pattern and strength of the incident signal.
