The VIA Envy VT1736 is a 2-channel, 32-bit/192KHz audio controller specifically designed to achieve cinema-quality audio recording and playback in high fidelity USB and MIDI system applications. With the advancement to 32-bit, 192 kHz support more points along the sound wave are recorded and saved, creating the most authentic listening experience when it is converted into analog sound during playback. The VT1736 brings highest audio quality to the prosumer which does not demand a full surround setup.
The highly integrated single chip USB audio solution is embedded with a number of crucial modules, including a standard 8032 MCU core, USB Transceiver, two I2C master and one slave controller, an I2S controller, a serial flash controller, an SPI port, phase-locked loop (PLLs) with internal oscillator, and a 3.3 V~ 2.0 V regulator.
The VT1736 also supports multi-channel PCM digital audio format up to 32-bit resolution and 192 kHz sample rate as well as multiple audio bit streams of up to 2 Input Streams and 2 Output Streams. Additionally, the I2S interface of the VT1736 is capable of supporting various customized configurations. An S/PDIF interface with one stereo output port and one stereo input port also supports up to a 24-bit resolution and 192 kHz sample rate. VT1736 also supports DSD stream output.
