Manual SDs-01 D 3.2.2003 17:45 Uhr Seite 3
INTRODUCTION
Thank you very much for purchasing iCLOCK or iCLOCK dp, Redundant
Multiple Clock Synthesizer & Video Reference Generator, from MUTEC!
About this Manual
The whole manual is related to both versions in general, iCLOCK and
iCLOCK dp. The individual differences are mentioned in the according
sections and chapters.
The structure of this manual refers to the normal process of installing
iCLOCK in a standard audio/video studio environment. Thus the chapters
are ergonomically sorted to provide a fast set-up. Before first power-on we
recommend to read the chapters INTRODUCTION and BRIEF INSTRUCTIONS
to get to know the general functionality of iCLOCK and to reach a fast
system integration.
The following chapters OPERATION and iCLOCK TECHNOLOGY describe
individual functions which enable the adaption of iCLOCK to every studio
environment. The chapters APPLICATION EXAMPLE and APPENDIX include
descriptions of favorable studio set-ups as well as all technical information.
If there are any uncertainties when operating the units which can not be
cleared up by the content of this manual, please feel free to contact your
local dealer or MUTEC directly. All contact details are included in chapter
WARRANTY REGULATIONS located at the beginning of the manual.
General Function Description
iCLOCK is a synchronizable, high-precision clock generator which is
designed to be the reference in digital audio and video studios as well
as broadcast and television stations. Based on a totally new concept
of frequency generation, developed by MUTEC, the unit offers an
unchallanged flexibility for synchronization of different devices to one
house clock. On this occasion iCLOCK breaks traditional, unflexible forms
of chaining input and output signals and allows for the first time their
completely free combination and scaleability.
iCLOCK‘s philosophy is addressed to provide the highest possible failure
safety for all outgoing clock signals which is needed especially for
broadcast stations or centralized clock distribution systems. With regards
to this functionality up to 3 independent external references can be auto-
detected and locked in a user-defined sequence without any phase-jumps
or interruptions in the outgoing signals. This applies also to external
clock frequency changes, e.g. from 44.1kHz to 48.0kHz or reference clock
changes, e.g. from video to GPS or AES11. Even if all external references
are lost, iCLOCK synthesizes the outgoing clock signals based on the
last incoming frequency constantly. If the absent reference clock returns
the synthesizer will lock gradually again based on iCLOCK’s SoftReLock
functionality which ensures interruption-free adjustments of all outgoing
clock signals. In this case a continous clock supply for all connected devices
is guaranteed during any operation mode.
For todays audio/video productions a precision synchronisation of the used
audio and video equipment is imperative. To reach the highest value of
accuracy the involved clock signals need to be synchronized and converted
without any phase drift. Therefore iCLOCK offers a unique, automatically
working signal management which observes the phase relationships of all
input and output signals and takes care of adjustments aligned to
AES11-1997/2003 and EBU R83-1996.
Using DDS-coupled frequency generation and latest DSP-based filtering
technologies in combination with an extremely low-jitter clock basis of
< 10ps (RMS), iCLOCK eliminates the jitter of incoming reference signals
completely. This ensures highest possible jitter attenuation for all outgoing
clock signals. As a result the synchronization of connected devices is much
more reliable and the sound quality of every AD/DA converter will be
increased significantly.
