Abstract :
An integrated 10 Gb/s clock and data recovery (CDR) circuit is fabricated using SiGe technology, It consists of a linear-type phase-locked loop (PLL) based on a single-edge version of the Hogge phase detector, a LC-tank voltage-controlled oscillator (VCO) and a tri-state charge pump. A PLL equivalent model and design method to meet SONET jitter requirements are presented. The CDR was tested at 9.529 GB/s in full operation and up to 13.25 Gb/s in data recovery mode. Sensitivity is 14 mV/sub pp/ at a bit error rate (BER)=10/sup -9/. The measured recovered clock jitter is less than 1 ps RMS. The IC dissipates 1.5 W with a -5 V power supply.
