Abstract
A device includes a first circuit having rows and columns of delay cells to generate delayed signals based on an input signal. The delayed signals are selectable and have a different delay from one another with respect to the input signal. The device is programmable based on a delay code. Different values of the delay code allow the device to select different delayed signals. The device may select one of the delayed signals from the first circuit for use as a timing signal in a second circuit of the device. The device may also use the delayed signals from the first circuit to evaluate a clock and data recovery circuit. In an embodiment, the circuits may be located on a single die.
