CM7030 Datasheet | C-Media

DESCRIPTION FEATURES 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™ Sing FX 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, 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 Live Streaming applications, minimizing the total BOM cost and design plexity. It also supports 1cap-less/anti-pop headphone driver, 3.5mm 4-ring bo-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 (~85d B SNR at +20d B pre-amp gain) can achieve high recording/monitoring performance for microphone input.
