CDB53L30
Evaluation Board for the CS53L30
Features
Description
• Analog or digital Inputs
The CDB53L30 board is a dedicated platform for testing
and evaluating the CS53L30, a low-power, quad-channel
microphone ADC with TDM output.
— Analog microphone or line inputs via TRS 1/8” jacks
— Digital microphone inputs via stake headers
To allow comprehensive testing of CS53L30 features and
performance, extensive software-configurable options are
available on the CDB53L30.
• Two CS53L30 devices support up to eight channels of
phase-aligned audio
• Onboard master clock generator
• S/PDIF transmitter interface via RCA and optical jacks
• External digital I/O via stake headers
— Serial audio port I/O
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.
— Control signal I/O
™
— External I²C control port I/O
• Flexible power-supply configuration
— USB or external power supply
• FlexGUI software control
The CDB53L30 also serves as the component and layout
reference for the CS53L30.
