SK100EL16Y
High Gain Differential Receiver
with Variable Output Swing
Description
Features
Functional Block Diagram
The SK100EL16Y is a high gain differential receiver with
variable output swing. Its VCTRL input controls the
amplitude of the Q
HG
and Q
HG
* outputs. The operating
range of the EL16Y control input, VCTRL, is from VBB
(large swing) to VCC (min swing), see Figure 2. Simple
control of the output swing can be obtained by a variable
resistor between the VBB and VCC pins, with wiper
driving CTRL. Typical application circuit and results
are described in Figures 1a, 1b, and 2.
The SK100EL16Y 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 EL16Y
as its current sink/source capability is limited. Whenever
used, the VBB pin should be bypassed to VCC via a 0.01
µF capacitor.
The VCTRL pin should be bypassed to VCC via a 0.01
µF capacitor when the pin is used.

Notes:
1.
100K circuits are designed to meet the DC specification shown in the table where transverse airflow
greater than 500 lfpm is maintained.
2.
Duty cycle skew is the difference between T
PLH
and T
PHL
propagation delay through a device.
3.
F
max
guaranteed for functionality only. See Figure 3 for typical output swing. VO
P-P
levels are guaranteed
at DC only.
4.
The device has a DC gain of ~140.
5.
Minimum input swing for which parameters are guaranteed.
6.
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 and is equal to VEE + 1.5V.
7.
VO
P-P
is obtained as follows: Voltages of Q
HG
and Q
HG
* outputs with respect to VCC are measured. The
absolute difference between a high and a low state is equal to VO
P-P
.
8.
The VOH and VOL limits apply when the V
CTRL
pin is left open. Otherwise, see figure 2.
