File Name: A 5Gb/s Link with Clock Edge Matching and Embedded Common Mode Clock for Low Power Interfaces
A 5Gb/s signaling system was designed and fabricated in TSMC’s 40nm LP CMOS process. A new clock/data skew minimization technique with a source-synchronous transmit clock delay line and integrating receiver tolerates high frequency transmit clock jitter and supports rapid turn-on without the clock buffer latency of conventional source-synchronous systems. A second method to minimize clock distribution via embedded clocking with superposition of clock in the common-mode was also explored.
