15.2 Transmit 64kHz Synchronization Interface Operation
In the transmit path, the framer will generate the appropriate AMI waveform with the correct bipolar
violations as described by G.703. If an 8kHz signal is present on the TS_8K_4 pin, the bipolar violations
will be generated synchronously with this signal. If it is absent, the part will arbitrarily generate the
bipolar violation at an 8kHz frequency.
