Table 5. EEPROM Serial ID Memory Contents – Soft Commands (Address A2h, byte 110)
Bit # Status / Control name Description Notes
7 TX_DISABLE State Digital state of TX_DISABLE input pin (logic 1 = TX_DISABLE asserted) Note 1
6 Soft TX_DISABLE Read/write bit for changing digital state of TX_DISABLE function Note 1,2
5 Reserved Note 3
4 Not supported Note 4
3 Not supported Note 5
2 Not supported Note 6
1 RX_SD State Digital state of the RX_SD output pin (logic 0 = RX_SD asserted) Note 1
0 Data Ready (Bar) Indicates transceiver is powered and real time sense data is ready(0 = ready) Note 7
Notes:
1. The response time for soft commands of the AFBR-5978Z is 100 ms as specied by the MSA SFF-8472.
2. Bit 6 is logic OR’d with the TX_DISABLED input pin. Either asserted will disable the transmitter.
3. Reserved bits will return “0” when read. A write to a reserved bit will be acknowledged but not stored.
4. A read from bit 4 will return “1”. A write will be acknowledged but not stored.
5. A read/write from/to bit 3 will be acknowledged and stored but will be ignored by the transceiver.
6. A read from bit 2 will return “0”. A write will be acknowledged but not stored.
7. AFBR-5978Z meets the MSA SFF-8471 data ready timing of 1000 ms.
Table 6. EEPROM Serial ID Memory Contents – Alarm and Warnings (Address A2h, bytes 112, 113, 116, 117)
Byte Bit Flag bit name Description
112 7 Temp high alarm Set when transceiver internal temperature exceeds high alarm threshold
6 Temp low alarm Set when transceiver internal temperature exceeds low alarm threshold
5 Vcc high alarm Set when transceiver internal supply voltage exceeds high alarm threshold
4 Vcc low alarm Set when transceiver internal supply voltage exceeds low alarm threshold
3-0 Reserved Note 1
113 7-6 Reserved Note 1
5 Rx OMA Margin low alarm Set when received Rx OMA Margin exceeds low alarm threshold, Note 2
4-0 Reserved Note 1
116 7 Temp high warning Set when transceiver internal temperature exceeds high warning threshold
6 Temp low warning Set when transceiver internal temperature exceeds low warning threshold
5 Vcc high warning Set when transceiver internal supply voltage exceeds high warning threshold
4 Vcc low warning Set when transceiver internal supply voltage exceeds low warning threshold
3-0 Reserved Note 1
117 7-6 Reserved Note 1
5 Rx OMA Margin low warning Set when receiver Rx OMA Margin exceeds low warning threshold, Note 2
4-0 Reserved Note 1
Notes:
1. Reserved bits will return “0” when read. A write to a reserved bit will be acknowledged but not stored.
2. Received optical modulation amplitude margin or Rx OMA margin is a measure for the reserve in OMA to Sensitivity.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to
each parameter in isolation, all other parameters having values within the recommended operation conditions. It
should not be assumed that limiting values of more than one parameter can be applied to the products at the same
time. Exposure to the absolute maximum ratings for extended periods can adversely aect device reliability.
