description features clockworks sy10h641l sy100h641l final 3.3v power supply pecl-to-ttl version of popular eclinps e111 guaranteed low skew specification latched input differential ecl internal design v bb output for single-ended operation 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 the sy10/100h641l are single supply, low skew translating 1:9 clock drivers. devices in the micrel- synergy 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 pull- downs), 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. 3.3v single supply 1:9 pecl-to-ttl 18 17 16 15 14 13 12 567891011 26 27 28 1 2 3 4 top view plcc 25 24 23 22 21 20 19 v t q 7 v t q 8 g t q 6 g t g t q 5 v t q 4 v t q 3 g t q 2 q 1 v t q 0 g t g t v t v bb d v e len g e d en pin configuration block diagram d q 0 q 1 q 2 q 3 v bb en d q 4 q 5 q 6 q 7 q 8 len dq pecl input ttl outputs pin function g t ttl ground (0v) v t ttl v cc (+3.0v) v e ecl v cc (+3.0v) g e ecl ground (0v) d, /d signal input (pecl) v bb v bb reference output (pecl) q 0 ?q 8 signal outputs (ttl) /en enable input (pecl) len latch enable input (pecl) pin names 1 rev.: e amendment: /0 issue date: march 2002
