SK10/100EL16X
High Gain Differential Receiver
with Variable Output Swing
HIGH-PERFORMANCE PRODUCTS
Description
The SK10/100EL16X 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 EL16X 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 SK10/100EL16X 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 EL16X as its current sink/source capability is limited.
Whenever used, the VBB pin should be bypassed to VCC
via a 0.01 µF capacitor.
Under open input conditions, the pulldown resistor on D,
pulldown and pullup resistors on D* will force the Q
HG
output LOW and Q
HG
* output HIGH. The VCTRL pin
should be bypassed to VCC via a 0.01 µF capacitor when
the pin is used.

Notes:
1. 10EL circuits are designed to meet the DC specifications shown in the table after thermal equilibrium
has been established. The circuit is in a test socket or mounted on a printed circuit board and transverse
airflow greater than 500 lfpm is maintained. Outputs are terminated through a 50W resistor to VCC–2.0V.
2. 100K circuits are designed to meet the DC specification shown in the table where transverse airflow
greater than 500 lfpm is maintained.
3. Duty cycle skew is the difference between T
PLH
and T
PHL
propagation delay through a device.
4. F
max
guaranteed for functionality only. See Figure 3 for typical output swing. VO
P-P
levels are
guaranteed at DC only.
5. The device has a DC gain of
~200.
6. Minimum input swing for which parameters are guaranteed.
7. 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.
8. 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
.
9. For part ordering description, see HPP Part Ordering Information Data Sheet.
