ECL Pro SY10EP11U 2.5V/3.3V/5V 1:2 DIFFERENTIAL ECL Pro SY100EP11U Micrel, Inc. SY10EP11U PECL/LVPECL/ECL SY100EP11U FANOUT BUFFER FEATURES 2.5V, 3.3V and 5V power supply options Guaranteed AC parameters over temperature: ECL Pro f > 3.0GHz MAX < 20ps output-to-output skew DESCRIPTION < 200ps t /t r f < 300ps propagation delay The SY10/100EP11U is a precision, high-speed 1:2 differential fanout buffer. Having within-device skews and Wide temperature range: 40C to +85C output transition times significantly improved over the Available in 8-pin (3mm) MSOP and SOIC packages 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. PIN NAMES CROSS REFERENCE TABLE Pin Function Micrel Semiconductor ON Semiconductor D PECL, LVPECL, ECL, LVECL Clock or Data Input: SY10EP11UZI/KI MC10EP11D/DT Internal 75k pulldown resistor. If left floating, SY10EP11UZI/KI MC10LVEP11D/DT pin defaults LOW, Q goes LOW. OUT SY100EP11UZI/KI MC100EP11D/DT /D PECL, LVPECL, ECL, LVECL complementary SY100EP11UZI/KI MC100LVEP11D/DT Clock or Data Input: Internal 75k pull-up and down resistors. If left open, default is V /2. When CC the input is not used, it can be left open. Q0, /Q0 PECL, LVPECL, ECL, LVECL Outputs: Q1, /Q1 Terminates to V 2V. CC V Positive Power Supply: Bypass with 0.1F//0.01F CC low ESR capacitors. V Negative Power Supply: For PECL operation, EE connect to GND. ECL Pro is a trademark of Micrel, Inc.
