Differential Receiver
PRELIMINARY
The SK10/100EL16TA-TD are differential receivers with
optional input/output terminations. The EL16TA-TD family
is pin-to-pin compatible with SK10/100EL16W and
Motorola’s MC10/100EL16 and MC10/100LVEL16, with
added features of input/output terminations. The different
options of input/output terminations of the EL16TA-TD
make them ideal for use in high frequency design
applications. It can also reduce the part count where
board space is scarce.
The SK10/100EL16TA has a 100Ω resistor across its
differential inputs. The output of this device has emitter
follower structure and must be terminated with 50Ω to
–2V. This device is used in applications where the driving
source has terminated outputs. Please refer to Figure 1
for more details.
• Extended Supply Voltage Range (VEE = –5.5V to
–3.0V, VCC = 0V) or (VCC = +3.0V to +5.5V, VEE
= 0V)
• High Bandwidth Output Transitions
• 300 ps Propagation Delay
• VBB Output
• Internal Input Resistors: Pulldown on D, Pulldown
and Pullup on D*
• ESD Protection of >4000V
• Specified Over Industrial Temperature Range:
–40^oC to 85^oC
• Available in 8 Pin SOIC Package
The SK10/100EL16TB has a 100Ω resistor and 8 mA
current sources across its differential inputs. The
latter will provide a DC path for the output currents of
the driving source. The output of this device has
emitter follower structure and must be terminated with
50Ω to –2V. This device is used in applications where
the driving source may not need output termination.
Please refer to Figure 2 for more details.
The SK10/100EL16TC has a 100Ω resistor across its
differential inputs and 8 mA current sources across its
differential outputs. This device is used in applications
where the driving source may not need output termination.
Please refer to Figure 3 for more details.

Reference Output Voltage
The SK10/100EL16TD has a 100Ω resistor across its
differential inputs, 50Ω series resistance, and 8 mA current
sources at its outputs. The outputs of this device may not
need any termination because of the internal output 50Ω
series resistor and current source. This device is used in
applications where the driving source may not need output
termination. Please refer to Figure 4 for more details.
The SK10/100EL16TA-TD 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
EL16TA-TD as its current sink/source capability is limited.
Whenever used, the VBB pin should be bypassed to VCC
via a 0.01 µF capacitor.
