The SK10/100EL14W is a 1:5 Clock Distribution Chip
designed specifically for low skew clock distribution
applications. This device is fully compatible with
MC100EL14 and MC100LVEL14.
The device can be driven by either differential or single-
ended ECL/PECL input signals. The SK10/100EL14W
provides a V
BB
output for either single-ended use or DC
bias for AC coupling to the device. V
BB
is an output pin
and should be used as a bias for the EL14W as its current
sink/source capability is limited. Whenever used, V
BB
should be bypassed to VCC via a 0.01 μF capacitor.
The EL14W features a multiplexed clock input to allow for
the distribution of a lower speed scan or test clock along
with the high speed system clock. When LOW (or left
open and pulled LOW by the input pulldown resistor) the
SEL pin will select the differential clock input. The Common
Enable pin (EN*) is synchronous so that the outputs will
only be enabled/disabled when they are already in the
LOW state. This avoids the chance of generating a runt
clock pulse when the device is enabled/disabled as can
happen with an asynchronous control. The internal flip-
flops are clocked on the falling edge of the input clock;
therefore, all associated specification limits are referenced
to the negative edge of the clock input.
Extended Supply Voltage Range: (VEE = –5.5V to
–3.0V, VCC = 0V) or (VCC = + 3.0V to +5.5V,
VEE=0V)
