50ps output-to-output skew

Synchronous enable/disable

Multiplexed clock input

75K internal input pull-down resistors

Available in 16-pin SOIC package

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 V

to the CLK input and bypassed to V

capacitor. The V

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.

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.

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.

DESCRIPTION

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

The EL15 features a multiplexed clock input to allow

The common enable (EN) is synchronous so that the

output is designed to act as the

output should be connected
