Integrated Circuit in QFN Package
Data Sheet
Description
The HSDL-7002 modulates and demodulates electrical
pulses from HSDL-3201 IrDA
transceiver module and
other IrDA
compliant transceivers. The HSDL-7002 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-7002 consists or two state machines – the SIR
(Serial InfraRed) Encode and SIR Decode blocks. It also
contains a sequential block Clock Divide that synthesizes
the required internal signal.
The HSDL-7002 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 trans-
mitter and received in either a standard 3/16 modulation
mode or a 1.63 µs pulse mode.
