10.7 Digital Clock Configuration

10.7.1 Digital Clock Overview
In order to provide a flexible and robust audio processing system, the device is equipped with a configurable
digital clocking system. The digital clock can generate various independent internal sample rates, or can
sync to an incoming AES3 signal. Figure 10-7 shows the various sample rates and options available.
In Figure 10-7, each circled C represents a choice point. A choice point is a user‐interface control that can
be configured using the Lake Controller software. Please refer to the Lake Controller Operation Manual for
further information.
Figure 10-7 indicates internally generated clocks
with base-rate multiples of 44.1 kHz or 48 kHz. This
should not be confused with the internal DSP
sample rate of 96 kHz.
The PLM digital clocking system can either generate its own internal clock, or synchronize to an incoming
external clock source via the AES3 digital input.
10.7.2 Clock Source Priorities
There are two options for clock source configuration: Manual Configuration or Automatic Detection.
