Use of data decisions for temporal placement of samplers |
摘要 |
A data receiver has a clock recovery and data sampling circuit. This has a fixed local oscillator for timing the data samples. A phase interpolator adjusts the phase of the clock signal in response to an early late detector which samples the waveform at the expected position of the edges. A further correction to the sampling position is made in response to the recent history of the data received. The correction is modelled on predictable jitter, for example, that in a transmitter caused by changes in data causing the supply voltage to drop. |
