产品叙述
The Synaptics® AudioSmart™ CX31988 is a USB Type-C™ standard high-speed, low-power audio codec for USB Type-C headset applications without requiring external XTAL. With on-chip ADC and DAC, microphone preamplifiers and a capless headphone amplifier, the CX31988 is a true single-chip solution for applications that demand high audio quality and lower power consumption.
The key features of the CX31988 include:
- High performance playback
- 384 kHz, 32-bit
- 120 dB dynamic range
- 130 dB SNR
- 100 dB THD+N
- Mono high-performance audio ADC
- 96 kHz, 24-bit
- 115 dB dynamic range
- -90 dB THD+N
A ground-referenced output removes the need for capacitors on the headphone output, ensuring consistent performance with a wide variety of transducers.
An integrated DC-DC converter supports internal dynamic voltage scaling, and frequency scaling mechanisms to reduce power consumption. The converter can also provide power for all peripheral devices connected to the board.
