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 a first analog signal corresponding to a first operating condition of said optoelectronic transceiver into a first digital value, and convert a second analog signal corresponding to a second operating condition of said optoelectronic transceiver into a second digital value;
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; and
an interface configured to enable a host external to the optoelectronic transceiver to access the first digital value using the first address and to access the second digital value using the second address.

Abstract
The circuit monitors operation of an optoelectronic transceiver that includes a laser transmitter and a photodiode receiver. The circuit includes analog to digital conversion circuitry configured to convert a first analog signal corresponding to a first operating condition of said optoelectronic transceiver into a first digital value, and convert a second analog signal corresponding to a second operating condition of said optoelectronic transceiver into a second digital value corresponding to a second operating condition. The circuit also includes a 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. The circuit includes an interface configured to enable a host external to the optoelectronic transceiver to access the first digital value using the first address and to access the second digital value using the second address.
