Popis: This paper describes the design of a 0.5-6.6 Gb/s fully-adaptive low-power quad transceiver embedded in low-leakage 28 nm CMOS FPGAs. Integration techniques enable the utilization of the transceiver in FPGAs with both wire-bond and flip-chip packages and resolve significant challenges with receiver input and transmitter output insertion loss, power integrity, ESD, and reliability. The transceiver clocking network provides continuous operation range up to the maximum speed and incorporates two wide-range ring-based PLLs for enhanced clocking flexibility. The receiver front-end utilizes a 3-stage CTLE with wide input common-mode to remove the post-cursor ISI. The CTLE is fully adaptive using an LMS algorithm and edge-based equalization. The transmitter utilizes a 3-tap FIR. The transceiver achieves BER 10-15 at 6.6 Gb/s over a 20 dB loss channel. Power consumption is 129 mW from 1.2 V and 1 V supplies.
