1 / 9 page 1 Precision Edge® SY100EP210U Micrel, Inc. M9999-120505 hbwhelp@micrel.com or (408) 955-1690 FEATURES ■ 2.5V and 3.3V power supply options ■ Guaranteed AC parameters over temperature: •fMAX > 3.0GHz • < 25ps within-device skew • < 250ps tr /tf • < 380ps propagation delay (differential) ■ Wide temperature range: –40°C to +85°C ■ Differential design ■ V BB output ■ Fully compatible with industry standard 100K I/O levels ■ Available in 32-pin TQFP Package The SY100EP210U is a high-speed, precision low skew 1-to-5 dual differential clock driver. HSTL inputs can be used when the EP210U is operating in PECL mode. The EP210U specifically guarantees critical AC parameters over temperature and voltage. Optimal design, layout, and processing minimize skew within device and from device-to-device. The SY100EP210U, as with most other ECL devices, can be operated from a positive VCC supply in PECL mode. This allows the EP210U to be used for high performance clock distribution in +3.3V or +2.5V systems. Single-ended input operation is limited to a VCC ≥ 3.0V in PECL mode, or VEE ≤ –3.0V in ECL mode. Designers can take advantage of the EP210U’s performance to distribute low skew clocks across the backplane or to multiple points on a board. 2.5V/3.3V DUAL 1:5 DIFFERENTIAL LVECL/LVPECL/HSTL CLOCK DRIVER DESCRIPTION Precision Edge® SY100EP210U Rev.: D Amendment: /0 Issue Date: December 2005 BLOCK DIAGRAM Qa0 /Qa0 Qa1 /Qa1 Qa2 /Qa2 Qa3 /Qa3 Qa4 /Qa4 CLKa /CLKa Qb0 /Qb0 Qb1 /Qb1 Qb2 /Qb2 Qb3 /Qb3 Qb4 /Qb4 CLKb /CLKb VBB 75kΩ 75kΩ VEE VEE VCC 75kΩ VEE 75kΩ 75kΩ VCC VEE 75kΩ Precision Edge is a registered trademark of Micrel, Inc.
