US 2010/0166434 A1 · SUBSCRIBER LINE INTERFACE CIRCUITRY WITH INTEGRATED SERIAL INTERFACES

Abstract

Methods and apparatus for communicating include communicating frames of data at a frequency f1 serially from a first device to a second device using a first unidirectional data line. The frames have a first timeslot allocation of s timeslots. A clock signal having a frequency f2 is generated within the second device, wherein f 2 f 1 ≈ n · s , wherein n>1. The first unidirectional data line is sampled every n clock cycles of the clock signal for a plurality of the timeslots.
