Function
Reflects the state of the TXDISABLE pin
Soft transmit disable STXDIS is Ored with TXDIS
to control the laser which will be turned off if one
of these two signals is set to 1
Reflects the state of RS1 (pin 10)
Reflects the state of RS0 (pin 4)
Soft rate select (sets the state of the RS0 pin)
Reflects the state of the TXFAULT pin
Loss Of Signal. Reflects the state of the RXLOS
pin

Operation
1 = disabled,
0 = enabled
1 = disabled
0 = enabled
1 = RS1 is high (>4.25 Gbps);
0 = RS1 is low (≤4.25 Gbps)
1 = RS0 is high (>4.25 Gbps)
0 = RS0 is low (≤4.25 Gbps)
1 = Set RS0 high
0 = Set RS0 low
1 = TXFAULT is high (fault)
0 = TXFAULT low (no fault)
1 = RXLOS is high (loss of signal)
0 = RXLOS is low (no loss of signal)
0 = POR complete, all analog data results
have been converted at least once
1 = POR and first ADC sample cycle in
progress
Operation
