An 18.24-Gb/s, 0.93-pJ/bit Receiver With an Input-Level-Sensing CDR Using Clock-Embedded C-PHY Signaling Over Trio Wires

This article presents a receiver (RX) with an input-level-sensing clock and data recovery (CDR) circuit for a C-PHY interface with trio wires. The proposed CDR circuit detects a “strong” signal from the clock-embedded three-phase-coded signals and recovers the 3-bit wire state and clock simultaneously based on the detected “strong” signal without the inherent switching jitter of conventional C-PHY...
