SINGLE SUPPLY 1:9

PECL-TO-TTL

SY100H641

FEATURES

■ Input frequencies up to 135MHz

Precision Edge

■ PECL-to-TTL version of popular ECLinPS E111

■ Guaranteed low skew specification

■ Latched input

DESCRIPTION

■ Differential internal design

The SY10/100H641 are single supply, low skew

translating 1:9 clock drivers. Devices in the Micrel H600

translator series utilize the 28-lead PLCC for optimal

power pinning, signal flow-through and electrical

performance.

The devices feature a 24mA TTL output stage with

AC performance specified into a 50pF load capacitance.

A latch is provided on-chip. When LEN is LOW (or left

open, in which case it is pulled LOW by the internal pull-

downs), the latch is transparent. A HIGH on the enable

pin (EN) forces all outputs LOW.

■ VBB output VECL for single-ended operation

■ Single +5V supply

■ Reset/enable

■ Extra TTL and ECL power/ground pins

■ Choice of ECL compatibility: MECL 10KH (10Hxxx)

or 100K (100Hxxx)

■ Available in 28-pin PLCC package

The 10H version is compatible with MECL 10KH ECL

logic levels. The 100H version is compatible with 100K

levels.
