LA Audio CLK - G4 - Manual (Page 15)

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.
