A 43.2-Gb/s clock and data recovery/demultiplexer (CDR/DMUX) integrated circuit (IC) implemented in InP heterojunction bipolar transistor (HBT) technology is demonstrated. The IC is fully integrated, requiring only a single external capacitor for complete functionality. The IC exceeds extrapolated SONET/SDH jitter tolerance specifications, operates with an industry-standard +3.3-V power supply, and dissipates 3.3 W.
