摘要： A deserializer for converting serial data into at least one parallel data includes a first flip-flop group, a second flip-flop group and a programmable frequency divider. The first flip-flop group includes a plurality of flip-flops connected in series, where the first flip-flop group is controlled by a first clock signal. The second flip-flop group includes a plurality of flip-flops, where the second flip-flop group is controlled by a second clock signal, and the flip-flops of the second flip-flop group are respectively connected to output nodes of the flip-flops of the first flip-flop group. The programmable frequency divider is coupled to each of the flip-flops of the second flip-flop group, and is utilized for receiving a control signal and generating the second clock signal by performing a frequency-dividing operation according to a frequency-dividing factor set by the control signal.

摘要： The present invention discloses a voltage level shifter capable of interfacing between two circuit systems having different operating voltage swings. The voltage level shifter comprises an input buffer having a low supply voltage for inverting an external input signal to an internal input signal, and an output buffer having a high supply voltage for inverting the internal input signal to an external output signal. The high level of the external input signal is lower than the high level of the external output signal. The voltage level shifter is designed such that the input buffer is operating to achieve a low-leakage and high-speed performance.
