Precision Edge® SY10H841 ® Precision SY100H841 Edge SINGLE SUPPLY QUAD PECL-TO-TTL W/LATCHED OUTPUT ENABLE Micrel, Inc. SY10H841 SY100H841 FEATURES ■ ■ ■ ■ 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 Precision Edge® DESCRIPTION The SY10/100H841 are single supply, low skew translating 1:4 clock drivers. 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. As frequencies increase to 40MHz and above, precise timing and shaping of clock signals becomes extremely important. The H841 solves several clock distribution problems such as minimizing skew (300ps), maximizing clock fanout (24mA drive), and precise duty cycle control through a proprietary differential internal design. The 10K version is compatible with 10KH ECL logic levels. The 100K version is compatible with 100K levels. ■ ■ ■ ■ Single supply Enable input Latch enable input Extra TTL and ECL power/ground pins to reduce cross-talk/noise ■ High drive capability: 24mA each output ■ Fully compatible with industry standard 10K, 100K I/O levels ■ Available in 16-pin SOIC package BLOCK DIAGRAM Q0 PIN NAMES Pin Q1 Q2 VBB D D D Q Q3 LEN Function GT TTL Ground (0V) VT TTL VCC (+5.0V) VE ECL VCC (+5.0V) GE ECL Ground (0V) D, D Signal Input (PECL) VBB VBB Reference Output (PECL) Q0 - Q3 Signal Outputs (TTL) EN Enable Input (PECL) LEN Latch Enable Input EN Precision Edge is a registered trademark of Micrel, Inc.
