Cmedia’s CM6502B is a highly-integrated USB audio single chip optimized for consumer headset solutions. This document is a user guide for CM6502B evaluation boards (EVB) that describes the board’s functions, I/O jacks, LEDs, controls and additional user notes.

CM6502B is compatible with USB audio Class 1.0, thus it can plug & play without additional software installation on the major operation systems. The internal DAC/ADC and S/PDIF out interface support 48K/44.1KHz sampling rate and 16bit resolution. 

All necessary analog and digital modules are embedded in CM6502B, including stereo DAC, headphone driver, stereo ADC, microphone pre-amp booster, PLL, regulator, and USB transceiver. Moreover, CM6502B integrates 5-band hardware equalizer (EQ) with four (4) default preset modes (default/flat, communication, gaming, and movie). The EQ preset gain parameters can also be customized for compensating the headphone SPL performance or to be complaint with TIA-920 standards.
