Abstract
A correlation circuit (200) for detecting a correct phase for data bits in a received data stream includes a clock generator (204) configured to generate a plurality of clock signals, each clock signal having a predetermined unique clock phase. A plurality of data correlators (210, 212, 214, 216, 218, 220) generate respective pass indications when respective unique clock phases are adequate for accurate detection of the data bits in the data stream. In response to the pass indications, a control circuit (206) provides a clock signal for clocking the data. The control circuit (206) includes a delay block (278) and decision logic (270) for selectively delaying one clock phase of the generated plurality of clock phases. The control circuit may provide one of the generated clock phases or a delayed clock phase for clocking the received data.
