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

NOTES:
1. Device-to-Device Skew considering HIGH-to-HIGH transitions at common VCC level.
2. Within-Device Skew considering HIGH-to-HIGH transitions at common VCC level.
3. Within-Device Skew considering LOW-to-LOW transitions at common VCC level.
4. All skew parameters are guaranteed but not tested.
5. Frequency at which output levels will meet a 0.8V to 2.0V minimum swing.
6. The fMAX value is specified as the minimum guaranteed maximum frequency. Actual operational maximum frequency may be greater.
7. VT = VE = +3.15V to +3.45V, (i.e. VE +/– 5%).
8. VT = VE = +3.0V to +3.6V, (i.e. VE +/– 10%).
