| 3.3V SINGLE SUPPLY 1:9 PECL-TO-TTL ClockWorksTM PRELIMINARY SY10H641L SY100H641L FEATURES s s s s s s 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 DESCRIPTION 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. s Reset/enable s Extra TTL and ECL power/ground pins s Choice of ECL compatibility: MECL 10KH (10Hxxx) or 100K (100Hxxx) s Available in 28-pin PLCC package BLOCK DIAGRAM TTL Outputs Q0 PIN CONFIGURATION Q6 VT Q7 VT Q8 GT 18 17 16 25 24 23 22 21 20 19 Q1 GT Q5 VT Q4 VT Q3 GT 26 27 28 1 2 3 4 5 6 7 8 9 10 11 GT TOP VIEW PLCC 15 14 13 12 Q2 VBB D D VE LEN GE EN GT Q2 VT Q1 VT PECL Input D D VBB Q5 LEN EN Q6 D Q Q4 PIN NAMES Pin GT VT VE GE D, /D Function TTL Ground (0V) TTL VCC (+3.0V) ECL VCC (+3.0V) ECL Ground (0V) Signal Input (PECL) VBB Reference Output (PECL) Signal Outputs (TTL) Enable Input (PECL) Latch Enable Input (PECL) Q7 VBB Q0 - Q8 /EN Q8 LEN Q0 GT Rev.: D Q3 Amendment: /0 1 Issue Date: May 2000 Micrel ClockWorksTM PRELIMINARY SY10H641L SY100H641L ABSOLUTE MAXIMUM RATINGS(1) Symbol VE (ECL) VT (TTL) VI (ECL) VOUT (TTL) IOUT (ECL) Rating Power Supply Voltage Input Voltage Disabled 3-State Output Output Current - Continuous - Surge Storage Temperature Operating Temperature Value -0.5 to +7.0 -0.5 to +7.0 0.0 to VE 0.0 to VT Unit V V V mA 50 100 -65 to +150 0 to +85 C C TRUTH TABLE D L H X X LEN L L H X /EN L L L H Q L H Q0 L Tstore TA NOTE: 1.
