DESCRIPTION
ECL Pro™
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 with a
0.01µF capacitor to V_CC (in PECL mode).
Under open input conditions (pulled to V_EE), internal
input clamps will force the Q output LOW.
