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: -40C to +85C Available in 8-pin (3mm) MSOP and SOIC packages
ECL ProTM
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.

PIN NAMES
Pin D Function PECL, LVPECL, ECL, LVECL Clock or Data Input: Internal 75k pulldown resistor. If left floating, pin defaults LOW, QOUT goes LOW. PECL, LVPECL, ECL, LVECL complementary Clock or Data Input: Internal 75k 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 Supply: Bypass with 0.1F//0.01F low ESR capacitors. Negative Power Supply: For PECL operation, connect to GND.
