GENERAL DESCRIPTION

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.

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 ADCMP580/ADCMP581/ADCMP582 are available in

a 16-lead LFCSP package.

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.
