DESCRIPTION
The SY100EL16S is a differential receiver with variable
output swing. This device is functionally equivalent to
the EL16V, with an additional input that control the output
amplitude.
The operating range of the EL16S control input is from
VBB (max. swing) to VCC (min. swing). Control of the
output swing can be obtained by a variable resistor
between the VBB pin and VCC with the wiper driving
VCTRL.
The EL16S provides a VBB output for either single-
ended use or as a DC bias for AC coupling to the device.
The VBB pin should be used only as a bias for the EL16S
as its current sink/source capability is limited. Whenever
used, the VBB pin should be bypassed to VCC via a
0.01µF capacitor.
Under open input conditions (pulled to VEE), internal
input clamps will force the Q output LOW.
