SECTION 1 OVERVIEW

1.1

Introduction

Cmedia’s HS-100B is highly-integrated USB audio single chip optimized for consumer

headset solutions. This document is a user guide for the demonstration boards (demo

boards) of HS-100B, which describes the board’s functions, I/O jacks, LEDs, controls and

some user notes.

HS-100B supports standard HID compliant volume control pins and playback mute/

recording mute, and it also offers playback operation and playback/record mute LED

indicators in order that users know the current status.

All necessary analog and digital modules are embedded in HS-100B, including stereo DAC,

headphone driver, Mono ADC, microphone pre-amp booster, PLL, regulator, and USB

transceiver.

In addition, internal cost effective embedded oscillator generates steady clock signal for

the operating clock, so the system designers of the products can reduce the BOM cost by

eliminating the crystal oscillator and the necessary circuit around it. End users will get

good sound experience either on PC or on game console.
