Precision Edge® SY10H641 ® Precision Edge SY100H641 SINGLE SUPPLY 1:9 PECL-TO-TTL Micrel, Inc. SY10H641 SY100H641 FEATURES ■ ■ ■ ■ ■ ■ Input frequencies up to 135MHz PECL-to-TTL version of popular ECLinPS E111 Guaranteed low skew specification Latched input Differential internal design VBB output VECL for single-ended operation Precision Edge® DESCRIPTION The SY10/100H641 are single supply, low skew translating 1:9 clock drivers. Devices in the Micrel H600 translator series utilize the 28-lead PLCC for optimal power pinning, signal flow-through and electrical performance. 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. The 10H version is compatible with MECL 10KH ECL logic levels. The 100H version is compatible with 100K levels. ■ ■ ■ ■ Single +5V supply Reset/enable Extra TTL and ECL power/ground pins Choice of ECL compatibility: MECL 10KH (10Hxxx) or 100K (100Hxxx) ■ Available in 28-pin PLCC package BLOCK DIAGRAM TTL Outputs Q0 PIN NAMES Pin Q1 Q2 Q3 PECL Input D D Q D Q4 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 - Q8 Signal Outputs (TTL) EN Enable Input (PECL) LEN Latch Enable Input (PECL) VBB Q5 LEN EN Q6 Q7 Q8 Precision Edge is a registered trademark of Micrel, Inc.
