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.
