The ADCMP580/ADCMP581/ADCMP582 are ultrafast voltage comparators fabricated on Analog Devices' proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. The ADCMP580 features CML output drivers; the ADCMP581 features reduced swing ECL (negative ECL) output drivers; and the ADCMP582 features reduced swing PECL (positive ECL) output drivers. All three comparators offer 180 ps propagation delay and 100 ps minimum pulse width for 10 Gbps operation with 200 fs random jitter (RJ). Overdrive and slew rate dispersion are typically less than 15 ps. The 5 V power supplies enable a wide -2 V to +3 V input range with logic levels referenced to the CML/NECL/PECL outputs. The inputs have 50 on-chip termination resistors with the optional capability to be left open (on an individual pin basis) for applications requiring high impedance input.
