The design of a 4 Gbps serial link transceiver in 0.35µm CMOS process is presented. The major factors limiting the performance of high-speed links are transmission channel bandwidth, timing uncertainty and on-chip frequency limitations. The design uses a combination of multi-level signaling (4-PAM) and transmit pre-emphasis to overcome the channel low-pass characteristics. High on-chip frequency signals are avoided by multiplexing and de-multiplexing the data directly at the pads. Timing recovery is done through over-sampling the data using multi-phase clocks generated from a low-jitter PLL. The design achieves a 4 Gbps data transmission rate, with a transmit data jitter of 53.2 ps (p-p), while consuming 879.4 mW of power from a 3.3 V supply.
