Introduction and Data

Introduction

Every piece of digital audio equipment has an internal sample clock 
that controls the timing of the A/D and D/A converters and the transfer 
of audio through its digital audio interfaces. For optimal converter 
performance, the clock must be stable and free of timing irregularities 
known as ‘jitter’ which can induce harmonic distortion and degrade 
stereo imaging. Additionally, to transfer digital audio between various 
devices the clocks must be synchronized to a common ‘master’ timing 
reference, without which clicks, pops and/or low-level noise will occur. 
Because most digital audio devices support only a single clock input or 
output, many users resort to chaining clock signals from the output of 
one device to the input of another. Chaining clocks can lead to clock 
phase differences and increased jitter as the signal proceeds down  
the chain.

The Lucid GENx192 Ultra Low Jitter Studio Master clock provides 
the ideal solution to most common clocking issues found in today’s 
recording, post-production, and broadcast environments by providing 
a low-jitter clock reference that can be distributed to a large number 
of devices simultaneously in multiple industry-standard formats and 
sample rates. The GENx192 features eight (8) word clock, four (4) AES 
clock, and two (2) S/PDIF clock outputs capable of operating at sample 
rates of up to 192 kHz.  The outputs are divided into two groups, each 
having independent control over sample rate. The GENx192 can also 
synchronize to and re-distribute external word clock or AES signals 
ranging from 28 to 216 kHz. Finally, it can also function as a 1x4 AES-3 
(audio) distribution amplifier.
