CLK-G4 (clock generator) :

Why use a clock generator:

A clock generator is used to synchronise equipment in a digital

audio environment. Most master clock generators on the market

also synchronise with video for post production, this can make a

master clock very expensive.

For applications which do not need a video lock, the CLK-G4

offers a very stable and precise master clock at an affordable

price. Also, each pair of outputs can independently deliver Word-

Clock or Super-Clock. (Super clock is a high speed clock

developed by Digi-Design, the frequency is 256 times that of

Word-Clock.

Using the CLK-G4 :

A cable with a characteristic impedance of 75 ohms must be

used, particularly with long distances and Super-Clock mode (any

video cable with BNC connectors). The CLK-G4 is able to drive

up to a 100 metre cable.
