The SK10/100EL15W is a low skew 1:4 clock distribution
chips designed explicitly for low skew clock distribution
applications. This device is fully compatible with
MC10EL15 & MC100EL15. The device can be driven by
either a differential or single-ended ECL or, if positive power
supplies are used, PECL input signal. If a single-ended
input is to be used, the VBB output should be connected
to the CLK* input and bypassed to VCC via a 0.01 μF
capacitor. The EL15W 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
EL15W as its current sink/source capability is limited.
Whenever used, the VBB pin should be bypassed to VCC
via a 0.01 μF capacitor.
The EL15W 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 pull-down resistor) the
SEL pin will select the differential clock input.
The common enable (EN*) is synchronous so that the
outputs will only be enabled/disabled when they are already
in the LOW state. This avoids any chance of generating a
runt clock pulse when the device is enabled/disabled as
can happen with an asynchronous control. The internal
flip-flop is 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)
