Abstract: A driving circuit and a pin output order arranging method are disclosed. The driving circuit includes (M*N) pins and an arranging module. A first pin˜an N-th pin of the (M*N) pins, a (N+1)-th pin˜an 2N-th pin of the (M*N) pins, . . . , a [(M?1)*N+1]-th pin˜a (M*N)-th pin of the (M*N) pins are arranged along a first direction in a specific distance spaced to form a first row of pins˜an M-th row of pins. The first row of pins˜the M-th row of pins are staggered along a second direction in a staggering way or an aligning way. M and N are integers larger than 1. The arranging module correspondingly arranges the pin output order of the (M*N) pins according to different application modes of the driving circuit.

Abstract: A sampling clock selection module for a serial data stream is disclosed. The sampling clock selection module includes a multi-phase generation circuit, a sampling circuit, a comparison unit and a logic operation unit. The multi-phase generation circuit generates a plurality of non-overlapping clock phases derived from a reference clock signal. The phase selection circuit selects a sampling clock phase under a calibration mode. The sampling circuit performs sampling on the serial data stream a plurality of times to generate a plurality of sampled values in response to the sampling clock phase. The comparison unit compares the sampled values with the serial data stream so as to update a plurality of flag signals. The logic operation unit performs a logic operation on the flag signals so as to select a sampling clock phase under a normal operation mode from the clock phases.
