Description
The SK10/100EL16V is a differential receiver with variable
output swing. Its VCTRL input controls the amplitude of
the Q and Q* outputs. The operating range of the
EL16V 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 circuits and results are described
in Figures 1a, 1b, and 2.
The SK10/100EL16V 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
EL16V 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 output
LOW and Q* 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 50Ω
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. V
CTRL
voltage range should be between V
BB
to V
CC
.
6. The device has a DC gain of ~40.
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 + 1.7V.
8. VO
P-P
is obtained as follows: Voltages of Q and Q* outputs with respect to VCC are measured. The
absolute difference between a high and a low state is equal to VO
P-P
.
9. Voltages referenced to VCC = 0V.
10. Minimum input swing for which parameters are guaranteed.
11. For standard ECL DC specifications, refer to the ECL Logic Family Standard DC Specifications Data
Sheet.
12. For part ordering description, see HPP Part Ordering Information Data Sheet.
