Power Power 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 Analog microphone or line inputs via TRS 1/8 jacks microphone ADC with TDM output. Digital microphone inputs via stake headers To allow comprehensive testing of CS53L30 features and Two CS53L30 devices support up to eight channels of performance, extensive software-configurable options are phase-aligned audio available on the CDB53L30. Onboard master clock generator Software options, such as register settings for the S/PDIF transmitter interface via RCA and optical jacks CS53L30, are configured with the FlexGUI software, which communicates with the CDB53L30 via USB from a External digital I/O via stake headers Windows -compatible computer. In addition, digital I/O Serial audio port I/O headers on the CDB53L30 allow external control signals Control signal I/O (from a host processor, for example) to configure and interface with the CS53L30 directly without the use of External IC control port I/O FlexGUI. Flexible power-supply configuration The CDB53L30 also serves as the component and layout USB or external power supply reference for the CS53L30.
