HF65411_VC1¶
USB HiFi Decoder with USB Input and Simultaneous I2S/SPDIF Output, Supporting I²S Master/Slave Modes and USB Connection Indicator
HF65411_VC1 is a USB HiFi audio decoder based on the A316-Mini-V1 module, designed specifically for digital audio applications that require simultaneous I²S and S/PDIF output.
HF65411_VC1 supports USB Audio Class 1.0/2.0 interfaces, and the I²S output supports both master mode (MASTER) and slave mode (SLAVE).
HF65411_VC1 provides a USB connection indicator output (X0D31): it outputs a high level when USB is connected and a low level when USB is disconnected, facilitating system status display and management.
