The MC100EP220 is a dual low skew 1–to–10 differential driver,
designed with clock distribution in mind. The VBB output provides a DC
threshold bias for single ended sources. The VBB can be connected to the
true input or the complementary input, the latter will produce an inverted
output. If used, the VBB output should be bypassed to ground.
•150ps Part–to–Part Skew
•50ps Output–to–Output Skew
•Differential Design
•VBB Output
•Voltage and Temperature Compensated Outputs
•Low Voltage VEE Range of –2.375 to –3.8V
•75kΩ Input Pulldown Resistors
The EP220 is specifically designed, modeled and produced with low
skew as the key goal. Optimal design and layout serve to minimize gate–
to–gate skew within a device, and empirical modeling is used to
determine process control limits that ensure consistent tpd distributions
from lot to lot. The net result is a dependable, guaranteed low skew
device.
To ensure that the tight skew specification is met it is necessary that
both pairs of the differential outputs are terminated into 50Ω, even if only
one side is being used. In applications which do not use all of the outputs,
it is best to leave unused pairs open to minimize power consumption in
the device.
The MC100EP220, as with most other ECL devices, can be operated from a positive VCC supply in PECL mode. This allows
the EP220 to be used for high performance clock distribution in +3.3V or +2.5V systems. Designers can take advantage of the
EP220’s performance to distribute low skew clocks across the backplane. In a PECL environment, series or Thevenin line
terminations are typically used as they require no additional power supplies. For more information on using PECL, designers
should refer to Motorola Application Note AN1406/D.
