SI-Bus transmit start sync signal
for slave devices. Asserted high
for three STxClk cycles to indicate
the A1 byte of each STS-1 in a
STS-3 signal on the STxData bus.
A 51.84 MHz clock derived from
the 155.52/622.08 MHz transmit
line clock. Generated for slave
devices that need a STS-1 bit rate
clock.
SI-Bus 19.44 MHz clock used to
transfer 8-bit SI-Bus data to the
slave devices.
SI-Bus receive start sync signal
for slave devices. Asserted high to
indicate the A1 byte of each STS-1
on the SRxData bus.
SI-Bus receive data sent to the
slave device.
Odd parity calculated over
SRxData[7:0].
