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 VBB (max. swing) to VCC (min. swing). Simple control
of the output swing can be obtained by a variable resistor
between the VBB pin and VCC with the wiper driving
VCTRL.
The EL16VS provides a VBB output for either singleended use or as a DC bias for AC coupling to the device.
The VBB pin should be used only as a bias for the EL16VS
as its current sink/source capability is limited. Whenever
used, the VBB pin should be bypassed to ground via a
0.01µF capacitor.
Under open input conditions (pulled to VEE), 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 tPLH and tPHL 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 VPP min. and 1V. The lower end of the CMR range varies 1:1 with VEE. The numbers in the spec table
assume a nominal VEE = –3.3V. Note for PECL operation, the VCMR (min) will be fixed at 3.3V – |VCMR (min)|.
