MICREL SY10EL32V, SY100EL32V Datasheet
DESCRIPTION
■ 3.3V and 5V power supply options
■ 510ps propagation delay
■ 3.0GHz toggle frequency
■ High bandwidth output transistions
■ Internal 75KΩ input pull-down resistors
■ Available in 8-pin SOIC package
The SY10/100EL32V are integrated ÷2 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 EL32V 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-on, the internal flip-flop will attain
a random state; the reset allows for the synchronization
of multiple EL32Vs in a system.

AC ELECTRICAL CHARACTERISTICS

NOTES:
1. Parametric values specified at: 10/100EL32V Series: -3.0V to -5.5V.
2. Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of ≈40.
3. The CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the HIGH level falls within the specified
range and the peak-to-peak voltage lies between VPP min. and 1V. The lower end of the CMR range varies 1:1 with VEE. The numbers in the spec table
assume a nominal VEE = –3.3V. Note for PECL operation, the VCMR (min) will be fixed at 3.3V – |VCMR (min)|.
