SK10EL89
Coaxial Cable Driver
HIGH-PERFORMANCE PRODUCTS
Features
Description
The SK10EL89 is a differential fanout gate specifically
designed to drive coaxial cables. This device is fully
compatible with MC10EL89. The SK10EL89 is especially
useful in digital video broadcasting. For this application,
since the system is polarity free, each output can be
used as an independent driver. The driver is capable of
outputting a gain of approximately 40 and produces
output swings twice as large as a standard ECL output.
When driving a coaxial cable, proper termination is
required at both ends of the line to minimize signal loss.
The 1.6V output swing allows for termination of both ends
of the cable while maintaining the required 800 mV swing
at the receiving end of the cable.

Industrial Temperature Range: –40oC to 85oC
Available in 8-pin SOIC (150 mils) Package
Pin Descriptions
Because of the larger output swings, the device cannot
be terminated into a standard VCC – 2.0V. All of the DC
parameters are tested with a 50Ω to VCC – 3.0V load.
The driver accepts a standard differential ECL input and
can run off a digital video broadcast standard –5.0V
supply.

Notes:
1. Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of 40 .
2. 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
and 1V. The lower end of the CMR range varies 1:1 with VEE and is equal to VEE + 2.2V.
(min)
3. Voltages referenced to VCC = 0V.
4. For standard ECL DC specifications, refer to the ECL Logic Family Standard DC Specifications Data
Sheet.
5. For part ordering description, see HPP Part Ordering Information Data Sheet.
