Abstract :
This paper describes the design of a 2.5 Gbps CMOS data serializer, including a low jitter multiphase phase-locked loop, a multiplexer, and an output buffer. High speed parallel to serial data conversion is toggled by the multiphase PLL. This serializer achieves a conversion rate of up to 312.5 Mbyte/s and a transmission speed of 2.5 Gbps. The measured RMS jitter is less than 6 ps from a 2.5 Gbps data output. The measured eye diagram meets OC-48 transition mask. Die size is 1062 μm×1020 μm.
