Interface Chips
• IEC 825-Class 1 Eye Safe
115.2 Kb/s and RXD-B for signal
rates of 576 Kb/s and 4.0 Mb/s.
The receiver is designed for maxi-
mum sensitivity to IrDA signals
and minimum sensitivity to signals
outside the IrDA optical wavelength
and frequency modulation of
interest. A receiver lens magnifies
the effective area of the PIN diode
to enhance sensitivity. The lens is
integral with the molded package
and contains a dye which absorbs
visible light. Receiver outputs
pulse low when the IR signal is
present. The power supply for the
PIN and preamplifier are filtered to
attenuate noise conducted from
external sources.
Applications for the HSDL-1100
include notebook PCs, LANs,
telephones, pagers, printers,
cameras, and industrial handheld
devices.

Description
The HSDL-1100 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.
The HSDL-1100 contains a high
speed, high efficiency, TS AlGaAs
870 nm LED, a silicon PIN
photodiode, and a bipolar, silicon
integrated circuit. The IC contains
an LED driver and a receiver
providing two output signals,
RXD-A for signal rates from 2.4 to
