ClockWorks™ SY10H641L SY100H641L FINAL 3.3V SINGLE SUPPLY 1:9 PECL-TO-TTL FEATURES 3.3V power supply PECL-to-TTL version of popular ECLinPS E111 Guaranteed low skew specification Latched input Differential ECL internal design VBB output for single-ended operation The SY10/100H641L are single supply, low skew translating 1:9 clock drivers. Devices in the MicrelSynergy 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 20pF 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. ■ 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 Q8 GT GT TTL Outputs Q7 VT PIN CONFIGURATION BLOCK DIAGRAM Q6 VT Q0 25 24 23 22 21 20 19 Q2 26 18 27 17 2 14 Q3 GT 3 13 28 1 12 D D Q 6 7 GT Q2 VT PECL Input Q4 15 4 5 Q3 VBB D D VE LEN GE EN 16 TOP VIEW PLCC 9 10 11 Q0 GT Q1 GT Q5 VT Q4 VT Q1 VT ■ ■ ■ ■ ■ ■ DESCRIPTION 8 PIN NAMES D VBB Pin Q5 Function LEN GT TTL Ground (0V) EN VT TTL VCC (+3.0V) VE ECL VCC (+3.0V) Q6 Q7 Q8 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) Rev.: E 1 Amendment: /0 Issue Date: March 2002 ClockWorks™ SY10H641L SY100H641L Micrel ABSOLUTE MAXIMUM RATINGS(1) Symbol Rating TRUTH TABLE Value Unit D LEN /EN Q L L L L H L L H X H L Q0 X X H L VE (ECL) VT (TTL) Power Supply Voltage –0.5 to +7.0 –0.5 to +7.0 V VI (ECL) Input Voltage 0.0 to VE V VOUT (TTL) Disabled 3-State Output 0.0 to VT V IOUT (ECL) Output Current - Continuous - Surge mA 50 100 Tstore Storage Temperature TA Operating Temperature –65 to +150 °C 0 to +85 °C NOTE: 1.
