NOT REMENDED FOR NEW DESIGNS 3.3V SINGLE SUPPLY QUAD PECL-TO-TTL W/LATCHED OUTPUT ENABLE Precision Edge® Precision SESYd Y110g00HHe88®4411LL SY10H841L SY100H841L Features - 3.3V power supply - Translates positive ECL to TTL (PECL-to-TTL) - 300ps pin-to-pin skew - 500ps part-to-part skew - Differential internal design for increased noise immunity and stable threshold inputs - VBB reference output - Single supply - Enable input - Latch enable input - Extra TTL and ECL power/ground pins to reduce cross-talk/noise - High drive capability: 24m A each output - Fully patible with industry standard 10K, 100K I/O levels - Available in 16-pin SOIC package Precision Edge® DESCRIPTION The SY10/100H841L are single supply, low skew translating 1:4 clock drivers. The devices feature a 24m A TTL output stage, with AC performance specified into a 20p F 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. As frequencies increase to 40MHz and above, precise timing and shaping of clock signals bees extremely important. The H841 solves several clock distribution problems such as minimizing skew (300ps), maximizing clock fanout (24m A drive), and precise duty cycle control through a proprietary differential internal design. The 10K version is patible with 10KH ECL logic levels. The 100K version is patible with 100K levels. BLOCK DIAGRAM PIN...
