Example
iD is synchronized by an external Word
Clock reference with 48.0k. The outputs are
adjusted to different clock multiples and
dividers (see adjacent diagramm). If the
external reference changes to 44.1k, only the
basis clock rate of the outgoing signals will
be adapted, the predefined clock multipliers
and dividers will remain unchanged!

iD TECHNOLOGY

Functional Principle

iD's principle operation is different to conventional products. The customer,
as a matter of priority, defines the clock rate multipliers and dividers and
formates which are constantly available at the outputs – not depending on
the clock rate of the incoming reference signal!
Input Reference Change
Output WCLK
from 192.0k
to 176.4k
Output WCLK
from 12.0k
to 11.025k
Functional principle during input reference change
Furthermore, unlike standard clock generators, iD's unique concept enables
to set all system functions during any operation mode. This is regardless of
whether the synthesizer is synchronized internally or by an external source
- which includes also the use of the varispeed function!
During the process of synchronization the system detects automatically use-
ful phase relationships between the reference input and generated output
signals. Adjustments aligned to AES11-1997/2003 and EBU R83-1996 will be
executed in realtime independently.

SoftReLock

SoftReLock is a special system routine executed by the synthesizer in every
operation mode of reference change or reference resynchronization.
Especially in cases of the later described SEQSYNC or CYCLESYNC functions,
SoftReLock guarantees a gradual and seamless synchronization update of
the internal signal generators, or all iD output signals respectively, to the
basic clock rate of a new or reestablished reference source. Also if different
reference types are synchronized in succession, e.g. AES11 with 48.0k to
Word Clock with 96.0k, the SoftReLock routine ensures interruption-free
and gently adjustment of iD's output signals to the new reference.
SoftReLock represents one of the most important functions to support
the system's ability providing continous clock supply under all imaginable
operation modes.
