A 2.488a11.2 Gb/s SerDes in 40 nm low-leakage CMOS with multi-protocol compatibility for FPGA applications

This paper presents the design and Silicon verification of a 2.488a11.2 Gbps multi-standard SerDes transceiver in a 40 nm low-leakage CMOS process. The paper explores the architectural and circuit techniques used to meet the stringent requirements of the high-speed SerDes and to mitigate the performance impact of the low-leakage process. A system modeling approach is described, which is used for optimizing the architectural trade-offs. The transceiver makes use of a low-jitter LC phase locked loop to enable high-reliability system design. The design has 420 fs RJrms and consumes 30.1 mW/Gbps at 11.2 Gbps.
