An analog to digital converter (ADC) circuit suitable for processing serial data at a fast rate includes a clock control block for receiving a reference strobe signal REF_STB, a reference clock signal REF_CLK, and number of bit control signals CONT-1, CONT-2. The clock control block outputs first and second internal clock signals CLK_A, and CLK_B, and a forwarding direction control signal CONT-3. The ADC circuit also includes a parallel analog to digital converter for receiving and converting analog signal into a parallel digital data synchronously with the first internal clock signal CLK_A. A parallel to serial transform logic control block then transforms the parallel digital data into serial digital data synchronously with the second internal clock signal CLK_B.
