Abstract
A quad-channel 0.6-3.2 Gb/s/channnel transceiver using eight independent phase-locked loops (PLLs) shows a 1-ps rms random jitter performance without interchannel interference. The PLL employs a folded starved inverter with high supply/substrate noise immunity and an analog coarse-tuning scheme for both seamless frequency acquisition and N-fold voltage-controlled- oscillator (VCO) gain reduction. A fixed-interval charge pumping is adopted for wide pumping-current range and large jitter tolerance. A wide-range delayed-locked loop (DLL) is utilized as a clock and reset generator for an elastic buffer. The transceiver, implemented in a 0.18-μm CMOS technology, operates across a 30-in FR-4 backplane up to 3.2 Gb/s/ch with a bit-error rate of less than 10-13.
