Method of monitoring an optoelectronic transceiver with multiple flag values for a respective operating condition
DCFirst Claim
1. A circuit for monitoring operation of an optoelectronic transceiver, which includes a laser transmitter and a photodiode receiver, said circuit comprising:
- analog to digital conversion circuitry configured to convert at least two analog signals corresponding to operating conditions of said optoelectronic transceiver into a first digital value corresponding to a first operating condition and a second digital value corresponding to a second operating condition;
memory configured to store the first digital value in a first memory location that is mapped to a predefined and unique first address and to store the second digital value in a second memory location that is mapped to a predefined and unique second address, wherein the first address and second address are known to a host external to the optoelectronic transceiver; and
an interface configured to enable the host to access the first digital value using the first address and to access the second digital value using the second address.

Abstract
An optoelectronic transceiver includes an optoelectronic transmitter, an optoelectronic receiver, memory, and an interface. The memory is configured to store digital values representative of operating conditions of the optoelectronic transceiver. The interface is configured to receive from a host a request for data associated with a particular memory address, and respond to the host with a specific digital value of the digital values. The specific digital value is associated with the particular memory address received from the host. The optoelectronic transceiver may further include comparison logic configured to compare the digital values with limit values to generate flag values, wherein the flag values are stored as digital values in the memory.
