Abstract
A transceiver module having integrated eye diagram opening functionality for reducing jitter is described. The transceiver module may include a transmitter eye opener and a receiver eye opener integrated in a single circuit. The transceiver module may also include serial control and various other integrated components. Other functionalities that may be integrated on the transceiver module include loopback modes, bypass features, bit error rate testing, and power down modes.
Claims11
An optical transceiver module, comprising:
- a serial electrical interface with an electrical output port and an electrical input port;
- a receive path comprising:
- an optical input port adapted to receive a first optical signal from external to the transceiver module;
- a receiver eye opener including a first port coupled to receive a first serial electrical data stream based on the first optical signal and a second port coupled to receive a reference clock signal, the receiver eye opener being adapted to retime and reshape the first serial electrical data stream using the reference clock signal;
- and
- the electrical output port of the serial electrical interface adapted to transmit the retimed and reshaped first serial electrical data stream to external to the transceiver module;
- and
- a transmit path comprising:
- an electrical input port of the serial electrical interface adapted to receive a second serial electrical data stream from external to the transceiver module;
- a transmitter eye opener including a first port coupled to receive the second serial electrical data stream and a second port coupled to receive the reference clock signal, the transmitter eye opener being adapted to retime and reshape the second serial electrical data stream using the reference clock signal;
- and
- an optical output port adapted to transmit a second optical signal to external to the transceiver module, the second optical signal based on the retimed and reshaped second serial electrical data stream.
