GENERATION CHIP

2/4, 4/5/6 CLOCK

generation chip 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 device can be driven

by either a differential or single-ended ECL/LVECL or, if

positive power supplies are used, PECL/LVPECL input

signal. In addition, by using the V

source can be AC-coupled into the device. If a single-

ended input is to be used, the V

connected to the /CLK input and bypassed to ground via

a 0.01 F capacitor. The V

the switching reference for the input of the S839V 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.

random state; the master reset (MR) input must be

asserted to ensure synchronization. For systems which

only use one S839V, the MR pin need not be exercised

as the internal divider designs ensures synchronization

between the

device.
