Abstract :
The paper presents a digital (clock and data ecovery) CDR that occupies 72 × 72 μm2 and dissipates 12 mW at 8 Gb/s from a 0.81 V power supply. The transceiver characteristics are summarized. The die micrograph of the dual port transceiver was also illustrated with the digital CDR, the VCO, and each lane highlighted.
