Single/Dual, Ultra-Fast, ECL-Output

Comparators with Latch Enable

General Description

Features

The MAX9691/MAX9692/MAX9693 are ultra-fast ECL

comparators capable of very short propagation delays.

Their design maintains the excellent DC matching char-

acteristics normally found only in slower comparators.

ꢀ 1.2ns Propagation Delay

ꢀ 100ps Propagation Delay Skew

ꢀ 150ps Dispersion

The MAX9691/MAX9692/MAX9693 have differential

inputs and complementary outputs that are fully com-

patible with ECL-logic levels. Output current levels are

capable of driving 50Ω terminated transmission lines.

The ultra-fast operation makes signal processing possi-

ble at frequencies in excess of 600MHz.

ꢀ 0.5ns Latch Setup Time

ꢀ 0.5ns Latch-Enable Pulse Width

ꢀ Available in µMAX and QSOP Packages

ꢀ +5V, -5.2V Power Supplies

The MAX9692/MAX9693 feature a latch-enable (LE)

function that allows the comparator to be used in a

sample-hold mode. When LE is ECL high, the compara-

tor functions normally. When LE is driven ECL low, the

outputs are forced to an unambiguous ECL-logic state,

dependent on the input conditions at the time of the

latch input transition. If the latch-enable function is not

used on either of the two comparators, the appropriate

LE input must be connected to ground; the companion

LE input must be connected to a high ECL logic level.
