GENERATION CHIP

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. The 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 V

coupled into the device. If a single-ended input is to be

used, the V

The V

reference for the input of the EL38/L under single-ended

input conditions. As a result, this pin can only source/

sink up to 0.5mA of current.

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.

synchronization of the internal dividers, as well as for

multiple EL38/Ls in a system.
