Description
The CDB53L30 board is a dedicated platform for testing
and evaluating the CS53L30, a low-power, quad-channel
microphone ADC with TDM output.
To allow comprehensive testing of CS53L30 features and
performance, extensive software-configurable options are
available on the CDB53L30.
Software options, such as register settings for the
CS53L30, are configured with the FlexGUI software, which
communicates with the CDB53L30 via USB from a
Windows
® -compatible computer. In addition, digital I/O
headers on the CDB53L30 allow external control signals
(from a host processor, for example) to configure and
interface with the CS53L30 directly without the use of
FlexGUI.
The CDB53L30 also serves as the component and layout
reference for the CS53L30.
