FINAL

■2.5V, 3.3V and 5V power supply options

■Guaranteed AC parameters over temperature:

•f

MAX > 3.0GHz

• < 20ps output-to-output skew

• < 200ps tr/t

• < 300ps propagation delay

■Wide temperature range: –40°C to +85°C

■Available in 8-pin (3mm) MSOP and SOIC packages

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 Function

D PECL, LVPECL, ECL, LVECL Clock or Data Input:

Internal 75kΩ pulldown resistor. If left floating,

pin defaults LOW, QOUT goes LOW.

/D 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.

Q0, /Q0 PECL, LVPECL, ECL, LVECL Outputs:

Q1, /Q1 Terminates to VCC –2V.

VCC Positive Power Supply: Bypass with 0.1µF//0.01µF

low ESR capacitors.

VEE Negative Power Supply: For PECL operation,

connect to GND.
