GENERAL DESCRIPTION  
The ADCMP580/ADCMP581/ADCMP582 are ultrafast voltage  
comparators fabricated on the Analog Devices, Inc. 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.  
The CML output stage is designed to directly drive 400 mꢀ into  
50 Ω transmission lines terminated to ground. The NECL output  
stages are designed to directly drive 400 mꢀ into 50 Ω terminated  
to −2 . The PECL output stages are designed to directly drive  
400 mꢀ into 50 Ω terminated to ꢀCCO − 2 . High speed latch  
and programmable hysteresis are also provided. The differential  
latch input controls are also 50 Ω terminated to an independent  
TT pin to interface to either CML or ECL or to PECL logic.  
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 ADCMP580/ADCMP581/ADCMP582 are available in a  
16-lead LFCSP_ꢀQ.  
The 5 ꢀ power supplies enable a wide −2 ꢀ to +3 ꢀ input  
range with logic levels referenced to the CML/NECL/PECL  
outputs. The inputs have 50 Ω on-chip termination resistors  
with the optional capability to be left open (on an individual  
pin basis) for applications requiring high impedance input.
