CDS LP FILTER TRANSMIT OUTPUT DRIVER TXO TX ON FIGURE 1: 78Q8392L/A03 General System Block Diagram Page HEARTBEAT FUNCTION The 10 MHz CD outputs are enabled for about 1 µs at approximately 1.1 µs after the end of each transmission. The heartbeat signal tells the DTE that the circuit is functioning. This is implemented by starting the heartbeat timer when the valid data signal indicates the end of a transmission ...
