rf! ClockWorks" 13V SINGLE SUPPLY QUAD mea SAA Salon 3L-TO-TTL OUTPUT ENABLE Asters SEMICONDUCTOR 3Y100HS842L. FEATURES DESCRIPTION @ 3.3V power supply The SY10/100H842L are singie supply, low skew @ Translates positive ECL to TTL (PECL-to-TTL) transiating 1:4 clock drivers. The devices feature a 24mA TTL output stage, with M 300ps pin-to-pin skew AC performance specified into a 20pF load capacitance. M 500ps part-to-part skew A HIGH on the enable pin (EN) forces all outputs LOW. @ Differential internal design for increased noise As frequencies increase to 40MHz and above, precise immunity and stable threshold inputs timing and shaping of clock signals becomes extremely @ Ves reference output important. The H842 solves several clock distribution problems such as minimizing skew 300ps}, maximizing iM Single supply clock fanout (24mA drive}, and precise duty cycle control @ Enable input through a proprietary differential internal design. @ Extra TTL and ECL power/ground pins to reduce The 10K version is compatible with 10KH ECL logic cross-taik/noise levels. The 100K version is compatible with 100K levels. @ High drive capability: 24mA each output @ ESD protection of 2000V @ Fully compatible with industry standard 10K, 100K VO levels @ Available in 16-pin Gullwing Dip package BLOCK DIAGRAM PIN CONFIGURATION TTL Outputs L/S art 16 1] Qs ees Fu 2 os EN [] 18] @ oo Ge{] 3 14] Qe Ve [] 4 Top View 13 [] vr Gullwing OH ots 12] vt te pftj6 wa Ves [| 7 10 [] Gr tt Qs arf] 8 91] Qo - LD Qs TCE as) ECL Input ' Pin Function GT TTL Ground (OV) VE TTL Vee (+3.3V) VE ECL Voc (+3.3V) GE ECL Ground (OV) DD Signal Input (PECL) VBB Ves Reference Output (PECL) Qo - Q3 Signal Outputs (TTL) EN Enable Input (PECL) 1999 Micrel-Syneray 5-282 Neue Date August 1380 ClockWorks PRELIMINARY SY10H842L SYNERGY SY100H842L.
