Bit(s)

Function

Operation

D[7]

TXDIS

Reflects the state of the TXDISABLE pin

1 = disabled,

0 = enabled

D[6]

STXDIS

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

1 = disabled

0 = enabled

D[5]

RS1S

Reflects the state of RS1 (pin 10)

1 = RS1 is high (>4.25 Gbps);

0 = RS1 is low (≤4.25 Gbps)

D[4]

RS0S

Reflects the state of RS0 (pin 4)

1 = RS0 is high (>4.25 Gbps)

0 = RS0 is low (≤4.25 Gbps)

D[3]

SRS0

Soft rate select (sets the state of the RS0 pin)

1 = Set RS0 high

0 = Set RS0 low

D[2]

TXFLT

Reflects the state of the TXFAULT pin

1 = TXFAULT is high (fault)

0 = TXFAULT low (no fault)

D[1]

LOS

Loss Of Signal. Reflects the state of the RXLOS

1 = RXLOS is high (loss of signal)

0 = RXLOS is low (no loss of signal)

D[0]

POR

MIC3003 power-on status

0 = POR complete, all analog data results

have been converted at least once

1 = POR and first ADC sample cycle in

progress
