Description
The HSDL-7001 modulates and
demodulates electrical pulses
from Hewlett-Packard’s
HSDL-1001 Infrared transceiver
module and other IrDA-compliant
transceivers. The HSDL-7001 can
be used with a microcontroller/
microprocessor that has a serial
communication interface (UART).
Prior to communication, the
processor selects the transmis-
sion baud rate. Serial data is then
transmitted or received at the
prescribed data rate.
The HSDL-7001 consists of two
state machines – the SIR (Serial
InfraRed) Encode and SIR Decode
blocks. It also contains a
sequential block Clock Divide
which synthesizes the required
internal signal.
The HSDL-7001 can be placed
into the Internal Clock Mode or
External Clock Mode. An external
crystal is needed for the Internal
Clock Mode. In applications
where the external 16XCLK
signal is provided, a crystal is not
needed.
There are two data transmission
modes. Data can be transmitted
and received in either a standard
3/16 modulation mode or a
1.63
µs pulse mode.
