GENERAL DESCRIPTION

The ADCMP572/ADCMP573 are ultrafast comparators

fabricated on Analog Devices, Inc.’s proprietary XFCB3 Silicon

Germanium (SiGe) bipolar process. The ADCMP572 features

CML output drivers, and the ADCMP573 features reduced

swing PECL (RSPECL) output drivers.

resistors are provided at both inputs with the optional capability

to leave open (on an individual pin basis) for applications

requiring high impedance inputs.

The CML output stage is designed to directly drive 400 mV into

50 Ω transmission lines terminated to between 3.3 V to 5.2 V.

The RSPECL output stage is designed to drive 400 mV into

50 Ω terminated to V_CCO− 2 V and is compatible with several

commonly used PECL logic families. The comparator input

stage offers robust protection against large input overdrive, and

the outputs do not phase reverse when the valid input signal

range is exceeded. High speed latch and programmable

hysteresis features are also provided.

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.

A flexible power supply scheme allows either device to operate

with a single +3.3 V positive supply and a −0.2 V to +1.2 V

input signal range, or with split input/output supplies to

support a wider −0.2 V to +3.2 V input signal range and an

independent range of output levels. 50 Ω on-chip termination

The ADCMP572/ADCMP573 are available in a 16-lead LFCSP

package.
