Abstract:

In one aspect, an integrated circuit (IC) system includes a receiver IC configured to receive a first clock signal and includes a feedback circuit configured to provide a feedback signal to a driver IC. The IC system also includes the driver IC configured to receive a second clock signal and includes a waveform generator configured to provide synthesized waveforms from DC to K-band, a serializer/deserializer (SERDES) to receive data from the waveform generator and to provide the signal to the receiver IC and a phase selection circuit to provide a phase selection signal to the first integrated circuit based on the feedback signal. The phase selection signal calibrates the signal from the SERDES and provides phase correction to the SERDES.
