FEATURES

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

■ Guaranteed AC parameters over temperature:

• f > 3.0GHz

ECL Pro™

MAX

• < 20ps output-to-output skew

• < 200ps t / t

DESCRIPTION

r

f

• < 300ps propagation delay

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.

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

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

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.

2. Place termination resistors as close to destination inputs as possible.

3. R resistor sets the DC bias voltage equal to V . For +3.3V systems R = 46Ω to 50Ω. For +5V systems, R = 110Ω.
