RECEIVER AND TRANSMISSION AND RECEPTION SYSTEM

摘要

A receiver is composed of a receiver-side amplifier which receives a clock signal, a receiver-side amplifier which receives a data signal, a variable delay circuit which generates a delay-adjusted clock signal and a delay-adjusted data signal by delaying the clock signal and the data signal, a latch circuit section which latches the delay-adjusted data signal in synchronous with the delay-adjusted clock signal, and a skew detecting circuit which generates skew detection data that by latching a specific data sequence transmitted as the data signal in synchronous with a first clock signal to Nth clock signal (N is an integer equal to or more than 2) with different delay times from the clock signal. The delay time in the variable delay circuit is controlled according to the skew detection data.

1. A receiver comprising:
a first receiving section configured to receive an external clock signal and output a clock signal; a second receiving section configured to receive an external data signal and output a data signal; a variable delay circuit configured to generate a delay-adjusted clock signal and a delay-adjusted data signal by delaying at least one of the clock signal and the data signal; a latch circuit section configured to latch the delay-adjusted data signal in synchronization with the delay-adjusted clock signal to output an output data signal; and a skew detecting circuit configured to latch a specific data sequence transmitted as the data signal or the delayed data signal obtained by delaying the data signal, in synchronization with first to Nth clock signals (N is an integer equal to or more than 2) with different delay times to the clock signal to generate skew detection data, and control the variable delay circuit to adjust a delay time of the at least one signal based on the skew detection data.
