■3.3V and 5V power supply options
■650ps propagation delay
■4.0GHz toggle frequency
■High bandwidth output transistions
■Internal 75kΩ input pull-down resistors
■Available in 8-pin SOIC package The SY10/100EL33/L are integrated ÷4 dividers. The
differential clock inputs and the VBB allow a differential,
single-ended or AC-coupled interface to the device. If
used, the VBB output should be bypassed to ground with
a 0.01µF capacitor. Also note that the VBB is designed to
be used as an input bias on the EL33/L only; the VBB
output has limited current sink and source capability.
The reset pin is asynchronous and is asserted on the
rising edge. Upon power-up, the internal flip-flops will
attain a random state; the reset input allows for the
synchronization of multiple EL33/Ls in a system.
