The ADCMP572/ADCMP573 are ultrafast comparators fabricated on Analog Devices, Inc.'s proprietar y XFCB3 Silicon Germanium (SiGe) bipolar process. The ADCMP572 features CML output drivers, and the ADCMP573 features reduced swing PECL (RSPECL) output drivers. Both devices offer 150 ps propagation delay and 100 ps minimum pulse width for 10 Gbps operation with 200 fs RMS random jitter (RJ). Overdrive and slew rate dispersion is typically less than 15 ps.
