The SY100EP16VS are differential receivers with
variable output swing. The devices are functionally
equivalent to the EP16V devices with an input that
controls the amplitude of the outputs. EP16VS is
commonly used as VCSEL laser driver.
The operational range of the EP16VS 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 EP16VS 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
EP16VS 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.

Note 1.
Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of
40 when output has a full swing.
Note 2.
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 and V
CC
= 0V. Note for PECL operation, the V
CMR
(min.) will be fixed at 3.3V
|V
CMR
(min.)|.
