Abstract
A clock and data recovery (CDR) circuit operates to recover a clock and sample data from full-rate and sub-rate data signals. The CDR circuit selectively shifts one or more of the sampling clocks based on the rate of a received data signal, facilitating accurate sampling of sub-rate data signals. A masking circuit selectively masks data output bits clocked by a selection of the sampling clocks, thereby outputting relevant sampled data.
