INTRODUCTION

The HS-100C is a highly-integrated, crystal-free USB audio single chip solution optimized typically for USB headset, headphone, and dongle (wireless adapter enabled) applications. All necessary analog and digital modules were embedded in the HS-100C, including stereo DAC and earphone driver; mono ADC; microphone pre-amp booster; PLL; regulator; and USB transceiver. Many features of the HS-100C are programmable with jumper pins or external EEPROM. Customers can customize unique USB VID / PID / Product String / Manufacture String and Max / Min / Initial volume settings via an external EEPROM. In addition, the HS-100C supports HID compliant volume control pins such as Playback Mute, Volume Up/Down and a Recording Mute pin which interacts with the Playback Operation LED and Recording Mute LED control pins. The HS-100C also comes with an anti-pop noise circuits design and internal oscillator which can operate without an external crystal oscillator.
