INTRODUCTION
The CM7030 is a highly integrated single chip designed especially for Live Streaming Microphones, Headsets, Mixer Boxes, Speakers, or other peripherals. It features Cmedia’s Xear™ SingFX vocal Echo/Reverb engine, Digital Parametric EQ, Smart Noise Suppression, AGC, Voice Prompts, and Vocal Fading circuits for general music. With SPDIF-Out, Analog I/O, digital/analog mixers, SARADC for potentiometers, embedded MCU, flash memory, and oscillator inside the chip, the CM7030 is a cost-effective and ease-of-use single chip solution to fulfill the Live Streaming applications, minimizing the total BOM cost and design complexity. It also supports 2 cap-less/anti-pop headphone drivers, 3.5mm 4-ring combo-jack swap & jack-detection, tri-color LED PWM driver which could enhance the end product features and ease-of-use. High SNR/THD of Mic-In ADC (~85dB SNR at +20dB pre-amp gain) can achieve high recording/monitoring performance for microphone input.
