Abstract: In one embodiment, an integrated circuit is disclosed. The integrated includes a general purpose processor, an interface circuit, and a calibration adapter circuit. The general purpose processor circuit generates calibration test inputs based on user instruction. The analog interface circuit may include a calibration bus circuit. The calibration bus circuit may receive the calibration test input from the general purpose processor circuit. The calibration adapter circuit is coupled to the calibration bus circuit and the general purpose processor circuit and transmits the calibration test inputs to the calibration bus circuit.

Abstract: The present embodiments relate to clock-data phase alignment circuitry in source-synchronous interface circuits. Source-synchronous interface standards require the transmission and reception of a clock signal that is transmitted separately from the data signal. On the receiver side, the clock signal must be phase shifted relative to the data signal to enable the capture of the data. Clock-data phase alignment circuitry is presented that may receive a differential clock with complementary clock signals CLK_P and CLK_N. An adjustable delay circuit and clock distribution network may delay clock signal CLK_P and provide the delayed clock signal to a storage circuit that may store the data signal. A replica clock distribution network and a replica adjustable delay circuit may form a feedback path and provide the delayed first clock signal back to clock phase adjustment circuitry which may control the adjustment of the adjustable delay circuit and the replica adjustable delay circuit.
