3.3V SINGLE SUPPLY
1:9 PECL-TO-TTL
ClockWorks™
PRELIMINARY
SY10H641L
SY100H641L
FEATURES
s 3.3V power supply
s PECL-to-TTL version of popular ECLinPS E111
s Guaranteed low skew specification
s Latched input
s Differential ECL internal design
s VBB output for single-ended operation
s Reset/enable
s Extra TTL and ECL power/ground pins
s Choice of ECL compatibility: MECL 10KH (10Hxxx)
or 100K (100Hxxx)
s Available in 28-pin PLCC package
DESCRIPTION
The SY10/100H641L are single supply, low skew
translating 1:9 clock drivers. Devices in the Micrel-
Synergy 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 20pF 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.
The 10H version is compatible with MECL 10KH ECL
logic levels. The 100H version is compatible with 100K
levels.
