Abstract

Disclosed is a receiver circuit comprising an analog-to-digital converter (ADC) circuit having an analog input, a clock input, and a digital output, and a clock divider circuit having a reference clock input and a phase selector input, and having a clock output coupled to the clock input of the ADC circuit. The clock divider circuit is configured to divide a reference clock signal coupled to the reference clock input at a reference clock frequency, to produce a clock output signal at an ADC clock frequency, at the clock output, such that the reference clock frequency is an integer multiple N of the ADC clock frequency. The clock divider circuit is further configured to select from among a plurality of selectable phases of the clock output signal, responsive to a phase selector signal applied to the phase selector input.
