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

ꢀ

_TTpin 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.
