Precision Edge SY10H842L Precision Edge Micrel, Inc. SY100H842L 3.3V SINGLE SUPPLY QUAD SY10H842L PECL-TO-TTL OUTPUT ENABLE SY100H842L FEATURES 3.3V power supply Precision Edge Translates positive ECL-to-TTL (PECL-to-TTL) 300ps pin-to-pin skew DESCRIPTION 500ps part-to-part skew Differential internal design for increased noise The SY10/100H842L are single supply, low skew immunity and stable threshold inputs translating 1:4 clock drivers. VBB reference output The devices feature a 24mA TTL output stage, with Single supply AC performance specified into a 20pF load capacitance. A HIGH on the enable pin (EN) forces all outputs LOW. Enable input As frequencies increase to 40MHz and above, precise Extra TTL and ECL power/ground pins to reduce timing and shaping of clock signals becomes extremely cross-talk/noise important. The H842 solves several clock distribution High drive capability: 24mA each output problems such as minimizing skew 300ps), maximizing Fully compatible with industry standard 10K, 100K clock fanout (24mA drive), and precise duty cycle control I/O levels through a proprietary differential internal design. The 10K version is compatible with 10KH ECL logic Available in 16-pin SOIC package levels. The 100K version is compatible with 100K levels.
