ClockWorksTM SY10H641A ClockWorksTM SY100H641A SINGLE SUPPLY 1:9 PECL-TO-TTL SYNERGY SY10H641A SY100H641A SEMICONDUCTOR FEATURES DESCRIPTION Input frequencies up to 80MHz PECL-to-TTL version of popular ECLinPS E111 Guaranteed low skew specification Latched input Differential ECL internal design VBB output 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) ESD protection of 2000V Fully compatible with Motorola MC10H641/100H641 Available in 28-pin PLCC package The SY10/100H641A are single supply, low skew translating 1:9 clock drivers. Devices in the 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 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 pulldowns), 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.
