ETC SY10EP11UZI

2.5V/3.3V/5V 1:2 DIFFERENTIAL
PECL/LVPECL/ECL
FANOUT BUFFER
FEATURES
DESCRIPTION
■ 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
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 (pulled to VEE), the Q outputs
will go LOW.
