Abstract
A device for compensating impedance and gain of a transmission interface is provided. The device includes a correcting and compensating unit, a clock data recovering unit, a decoder, a calculating unit, and an adaptive control unit. The correcting and compensating unit is used to receive a channel signal, and compensate the channel signal according to a control signal to generate a compensation signal. The clock data recovering unit is used to receive the compensation signal and generate a data signal. The decoder is used to decode the data signal and perform detection to generate error information and correct information. The calculating unit is used to count times of generating the error information and times of generating the correct information to accordingly generate reference data. The adaptive control unit is used to receive the reference data and perform calculation to generate the control signal.
