We present a 40-Gbit/s-class clock and data recovery (CDR) circuit with a new lock detector. The lock detector operates robustly with a linear-type phase detector. The CDR IC was fabricated using InP/InGaAs HBTs. Error-free operation and wide eye opening were confirmed for 40, 43, and 45-Gbit/s PRBS with a length of 2/sup 31/-1. By attaching a frequency search and phase control (FSPC) circuit to the chip, the CDR circuit pulls in throughout a 39-45 Gbit/s range. The fabricated IC dissipates 1.89 W at a supply voltage of -4.5V.
