Taiwan Xinchuang SSS1700 The latest version of the Chinese manual |SSS1700 The latest Chinese specification |SSS1700 datasheet Chinese explanation
SSS1700 It's Taiwan Xinchuang SSS Following SSS1629/SSS1630 A new USB Audio control chip .SSS1700 comparison SSS1629 and SSS1630, It has the following advantages :
1. Whole USB Audio design circuit without capacitor output , Chip built in 12MHz Crystal oscillator , Reduce peripheral devices , The whole scheme BOM Cost reduction , The size of board and frame can be made smaller .
2.SSS1700 The sound quality of the chip has been greatly improved , Support 96 KHz 24 Bit sampling rate and external audio codec (24 position /96 KHz I2S Input and output ), Compare SSS1629 Support only 48HZ 16 Bit sampling rate , You can give user Provide a better auditory experience .
3.SSS1700 The overall bottom noise of the chip is greatly reduced , The average bottom noise of the chip is about 60DB about .
4.SSS1700 Support 3.5MMM 4 Segmental American standard / British standard automatic switching , Broaden the applicable scenarios , The switching circuit in the design process is reduced .
5.SSS1700 Support Mciro USB、Type-C 3.1 Interface ,lightning Interface , Headphones can be realized 、 Microphone function . Call support 、 Hang up 、 Volume increase and decrease function .
