ClockWorks™ SY10H646L SY100H646L 3.3V SINGLE SUPPLY OCTAL PECL/TTL-TO-TTL FEATURES DESCRIPTION ■ 3.3V power supply ■ PECL/TTL-to-TTL version of popular ECLinPS E111AE/LE ■ Guaranteed low skew specification ■ Three-state enable ■ Differential internal design ■ VBB output for single-ended operation ■ Extra TTL and ECL power/ground pins ■ Choice of ECL compatibility: 10K or 100K ■ Matched high and low output impedance ■ Available in 28-pin PLCC package The SY10/100H646L are single supply, low skew translating 1:8 clock drivers. Devices in the MicrelSynergy H600 translator series utilize the 28-lead PLCC for optimal power pinning, signal flow-through and electrical performance. The single supply H646L is similar to the HA643 which is a dual supply 1:8 version of the same function. These devices feature a 24mA TTL output stage, with AC performance specified into a 20pF load capacitance. The 10H version is compatible with 10K ECL logic levels. The 100H version is compatible with 100K levels.
