SY100EL16VS
DESCRIPTION
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碌F capacitor.
Under open input conditions (pulled to V
EE
), internal
input clamps will force the Q output LOW.
