Data Sheet

The HSDL-7002 modulates and demodulates electrical pulses from HSDL-3201 transceiver module and other 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 transmission 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 transmitter and received in either a standard 3/16 modulation mode or a µs pulse mode.
