Precision Edge

DESCRIPTION

■ 75KΩ internal input pull-down resistors

■ Available in 16-pin SOIC package

The SY10/100EL15 are low skew 1:4 clock distribution

chips designed explicitly for low skew clock distribution

applications. 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 0.01µF

capacitor. The VBB output is designed to act as the

switching reference for the input of the EL15 under single-

ended input conditions, as a result this pin can only

source/sink up to 0.5mA of current.

The EL15 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.
