Description
SK10/100EL16V
Differential Receiver
with Variable Output Swing
.eatures
The SK10/100EL16V is a differential receiver with variable • Extended Supply Voltage Range: (VEE = –5.5V to
output swing. Its VCTRL input controls the amplitude of
–3.0V, VCC = 0V) or (VCC = +3.0V to +5.5V,
the Q and Q* outputs. The operating range of the
VEE = 0V)
EL16V control input, VCTRL, is from VBB (large swing) • High Bandwidth Output Transitions
to VCC (min swing), see Figure 2. Simple control of • 300 ps Propagation Delay
the output swing can be obtained by a variable resistor • VBB Output
between the VBB and VCC pins, with wiper driving CTRL. • Internal Input Resistors: Pulldown on D, Pulldown
Typical application circuits and results are described
and Pullup on D*
in Figures 1a, 1b, and 2.
• Q Output will Default Low with Inputs Open or at VEE
• New Differential Input Common Mode Range
The SK10/100EL16V provides a VBB output for either • ESD Protection of >4000V
single-ended use or as a DC bias for AC coupling to the • Specified Over Industrial Temperature Range:
device. The VBB pin should be used only as a bias for the
–40oC to 85oC
EL16V as its current sink/source capability is limited. • Available in Both 8 Pin SOIC (150 mil) and MSOP
Whenever used, the VBB pin should be bypassed to VCC
(3mm x 3mm) Packages
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.
