ClockWorks™ SINGLE SUPPLY 1:9 SY10H641 PECL-TO-TTL SY100H641 FINAL FEATURES DESCRIPTION Input frequencies up to 135MHz The SY10/100H641 are single supply, low skew translating 1:9 clock drivers. Devices in the Micrel- PECL-to-TTL version of popular ECLinPS E111 Synergy H600 translator series utilize the 28-lead PLCC Guaranteed low skew specification for optimal power pinning, signal flow-through and Latched input electrical performance. Differential internal design The devices feature a 24mA TTL output stage with AC performance specified into a 50pF load capacitance. VBB output VECL for single-ended operation A latch is provided on-chip. When LEN is LOW (or left Single +5V supply open, in which case it is pulled LOW by the internal pull- Reset/enable downs), th
