Master Clock System 3 Hardware Components

System Reference, January 2001

For the master clock generator on the clock board,

Note that there are some restrictions about maximum

resolution that can be programmed on the software for

digital channels using fixed timing. You can avoid them if

timing equations are used.

Master Clock Distribution In the case of a single master clock, the master clock of the

digital clock domain is used for both digital channel

boards and analog modules. The master clock generated

from the clock board in cardcage #1 on the 512-pin

testhead or #5 on the 1024-pin testhead or the digital clock

domain’s AMC is distributed around the ring of all boards

in other cardcages. Hence, both digital channel boards and

analog modules use the master clock of the digital clock

domain.

In the cage of two master clocks, the master clock of the

digital clock domain is used for all the digital channel

boards. The master clock generated from the clock board

in cardcage #1 on the 512-pin testhead or #5 on the 1024-

pin testhead or the digital clock domain’s AMC is distrib-

uted around the ring of all digital boards and some analog

modules in other cardcages.

For each analog module, you can select the desired clock

domain from the digital or analog clock domains. If you

select the master clock of the digital clock domain for an

analog module, the analog module uses the same master

clock used for the digital channel boards. That is, it uses

one master clock for both digital channel boards and

analog modules.

If you select the master clock of the analog clock domain,

the analog module uses the master clock generated from

the clock board in it’s own cardcage or the analog clock

domain’s AMC. This means it uses a different master clock

from the master clock of the digital clock domain.
