Figure 1.

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 three 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.

APPLICATIONS

Automatic test equipment (ATE)

High speed instrumentation

Pulse spectroscopy

Medical imaging and diagnostics

High speed line receivers

Threshold detection

Peak and zero-crossing detectors

High speed trigger circuitry

Clock and data signal restoration

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

50 Ω transmission lines terminated to ground. The NECL

output stages are designed to directly drive 400 mV into 50 Ω

terminated to −2 V. The PECL output stages are designed to

directly drive 400 mV into 50 Ω terminated to V_CCO− 2 V. High

speed latch and programmable hysteresis are also provided. The

differential latch input controls are also 50 Ω terminated to an

independent V_TTpin to interface to either CML or ECL or to

PECL logic.

GENERAL DESCRIPTION

The ADCMP580/ADCMP581/ADCMP582 are ultrafast voltage

comparators fabricated on Analog Devices, Inc.’s 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 ADCMP580/ADCMP581/ADCMP582 are available in a

16-lead LFCSP package.

The three comparators offer 150 ps propagation delay and 100

ps minimum pulse width for 10 Gbps operation with 200 fs

random jitter (RJ). Overdrive and slew rate dispersion is

typically less than 25 ps.
