The SY100EL16VS are differential receivers with
variable output swing. The devices are functionally
equivalent to the EL16V devices with an input that control
the amplitude of the outputs.
The operational range of the EL16VS control input is
from V
BB
(max. swing) to V
CC
(min. swing). Simple control
of the output swing can be obtained by a variable resistor
between the V
BB
pin and V
CC
with the wiper driving
V
CTRL
.
The EL16VS provides a V
BB
output for either single-
ended use or as a DC bias for AC coupling to the device.
The V
BB
pin should be used only as a bias for the EL16VS
as its current sink/source capability is limited. Whenever
used, the V
BB
pin should be bypassed to ground via a
0.01
F capacitor.
Under open input conditions (pulled to V
EE
), internal
input clamps will force the Q output LOW.

NOTES:
1. Parametric values specified at:
100EL16VS Series:
3.0V to 5.5V.
2. Duty cycle skew is the difference between a t
PLH
and t
PHL
propagation delay through a device.
3. Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of
40 when output has a full swing.
4. 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)|.
