ABSTRACT:
A synchronous circuit implements a bypass mode for use in conjunction with an inductive-capacitive (“LC”) buffer. The LC buffer receives differential conventional clock signals, and generates buffered differential conventional clock signals. A synchronous circuit, such as a latch, includes at least two clock receivers. The conventional clock signal is input to the first clock receiver, such as a transistor, and an auxiliary clock is input to a second clock receiver. The conventional clock signal provides timing for the synchronous circuit under a normal mode of operation, and the auxiliary clock signal provides timing for the synchronous circuit under a test mode of operation at a frequency lower than the conventional clock signal.
