PCM6xx0Q1EVM-PDK Hardware Settings
The PCM6xx0Q evaluation module has several input configuration options and offers extensive flexibility
that allows the user to evaluate the device in multiple operation modes. The different operation modes are
highlighted in this section.
shows the architecture of the inputs to the evaluation module.
Figure 7. PCM6xx0EVM Input Architecture for Channels 1 and 2
The IN1 and IN2 input architecture allows these two channels to be quickly configured to support any of
the supported operation modes. The IN1P and IN1M pins of the PCM6xx0 can optionally connect to an
onboard microphone for quick evaluation of a microphone in AC- or DC-coupled modes. Jumper
configuration details can be found in
As shown in
, the input architecture for channels 3-6 of the PCM6xx0Q1EVM is streamlined.
These channels support only AC-coupled line inputs by default, however DC-coupled line and Mic inputs
are supported though the removal or replacement of R34-R45.
lists the recommended values for
bias resistors for AC-coupled inputs across the MICBIAS voltage and input swing.
