Description

The HSDL-7000 performs the modulation/demodulation function used to both encode and decode the electrical pulses from the IR transceiver. These pulses are then sent to a standard UART which has a BAUDOUT signal available externally. This signal is 16 times the selected baud rate. In applications where the 16XCLK is not available, an external means of generating the 16XCLK must be designed.

The HSDL-7000 is comprised of two state machines the serial IR encode and the serial IR decode blocks. Each of these blocks derives their timing from the 16XCLK input signal from the UART. The Encode block is driven by the negative edge triggered TXD signal from the UART. This initiates the modulation state machine resulting in the 3/16 modulated IR_TXD  signal which drives the IR transceiver module, HSDL-1000. The IR Decode block is driven by the negative edge triggered IR_RCV signal from the HSDL-1000. After this signal is demodulated and stretched, it drives the RCV signal to the UART.
