Transceiver devices with transmitter and receiver frequency control

A re-timer device comprising:

• first transceiver circuitry configured to:
• generate a first clock signal;
• generate a first frequency offset value based on a first input signal and the first clock signal, wherein the first input signal has a first frequency and the first clock signal has a second frequency different than the first frequency;
• and
• output the first frequency offset value;
• and
• second transceiver circuitry configured to:
• receive the first frequency offset value;
• and
• output a first output signal based on the first frequency offset value and the first input signal.

A method comprising:

• generating a first clock signal;
• receiving a first input signal;
• generating, via first transceiver circuitry, a first frequency offset value based on the first input signal and the first clock signal, wherein the first input signal has a first frequency and the first clock signal has a second frequency different than the first frequency;
• and
• outputting the first frequency offset value.
