The SY10/100EL32V are integrated
2 dividers. The
differential clock inputs and the V
BB
allow a differential,
single-ended or AC-coupled interface to the device. If
used, the V
BB
output should be bypassed to ground with
a 0.01
F capacitor. Also note that the V
BB
is designed to
be used as an input bias on the EL32V only; the V
BB
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
(1)
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 V
PP
min. and 1V. The lower end of the CMR range varies 1:1 with V
EE
. The numbers in the spec table
assume a nominal V
EE
= 3.3V. Note for PECL operation, the V
CMR
(min) will be fixed at 3.3V |V
CMR
(min)|.
