Micrel, Inc. 2.5V/3.3V/5V 1:2 DIFFERENTIAL PECL/LVPECL/ECL FANOUT BUFFER ECL Pro™ ECSLSYY1P10r00oEEPP™1111UU SY10EP11U SY100EP11U FEATURES ■ 2.5V, 3.3V and 5V power supply options ■ Guaranteed AC parameters over temperature: fMAX > 3.0GHz < 20ps output-to-output skew < 200ps tr / tf < 300ps propagation delay ■ Wide temperature range: –40°C to +85°C ■ Available in 8-pin (3mm) MSOP and SOIC packages ECL Pro™ DESCRIPTION The SY10/100EP11U is a precision, high-speed 1:2 differential fanout buffer. Having within-device skews and output transition times significantly improved over the EL11V, the EP11U is ideally suited for those applications which require the ultimate in AC performance. The differential inputs of the EP11U employ clamping circuitry to maintain stability under open input conditions. If the inputs are left open, the Q outputs will go LOW.

If left floating, pin defaults LOW, QOUT goes LOW. PECL, LVPECL, ECL, LVECL complementary Clock or Data Input: Internal 75kΩ pull-up and down resistors. If left open, default is VCC/2. When the input is not used, it can be left open. PECL, LVPECL, ECL, LVECL Outputs: Terminates to VCC –2V. Positive Power Suppl...
