SK100EL34W
÷2, ÷4, ÷8 Clock Generation Chip
Description
.eatures
.unctional Block Diagram
The SK100EL34W are low skew, ÷2, ÷4, ÷8 clock
generation chips designed explicitly for low skew clock
generation applications.
The internal dividers are
synchronous to each other, therefore, the common output
edges are all precisely aligned.
This device is
functionally compatible with On-Semiconductor’s
MC100EL34. These devices can be driven by either a
differential or single-ended ECL or, if positive power
supplies are used, PECL input signal. In addition, by
using the VBB output, a sinusoidal source can be AC-
coupled into the device. The EL34W provides a VBB
output for single-ended use or DC bias for AC coupling
to the device.
VBB is an output pin and should be
used as a bias for the EL34W as its current source/
sink capability is limited up to 0.5 mA.
Whenever
used, the VBB output should be bypassed to VCC via a
0.01 F capacitor.
The common enable (EN*) is synchronous so that the
internal dividers will only be enabled/disabled when the
internal clock is already in the LOW state. This avoids any
chance of generating a runt clock pulse on the internal
clock when the device is enabled/disabled as can happen
with an asynchronous control. An internal runt pulse could
lead to losing synchronization between the internal
divider stages. The internal enable 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.
Upon start-up, the internal flip-flops will attain a random
state; the master reset (MR) input allows for the
synchronization of the internal dividers, as well as for
multiple EL34Ws in a system.

–5.5V, VCC = 0V) or (VCC = +3.0V to +5.5V,
