Product Information

Back to top
CM7001 is an enhanced and a versatile voice and audio processor system-on-chip (SoC) that is empowered by Cmedia Xear™ sound technologies. For voice communication applications, CM7001 provides Xear™ VoClear close-talk Environmental Noise Cancellation (ENC), far-talk Smart Voice Capture (SVC), Voice Brilliant (HD Voice), AEC, Long Distance Recording (LDR), and Magic Voice for uplink voice sending. It also features Smart Receiver, Noise Reduction, and Voice Brilliant for downlink voice receiving. It could fulfill most communication and voice recognition demands on smartphones, tablets, headsets, speakerphones, smart TV webcam or remote, and a whole lot more. For audio playback applications, CM7001 provides advanced Xear™ Surround Headphone, Sound Expander, and Sonic technologies that dramatically enhances the audio experience of smartphones, tablets, headsets, docking stations and boom boxes. CM7001 is a tiny but powerful voice and audio engine for various applications.

CM7001 is powered by a 32-bit DSP computing core with multiple operation clock and power management options. It integrates all necessary ADC / DAC / Digital Mic / I2S / I2C / PLL / Regulator flexible function blocks and I/O interfaces for easy integration in existing smartphone and embedded platforms.

Figure 5.1 shows an internal block diagram of the CM7001 voice processor. Featuring a neat design, it makes an ideal voice capturing and noise canceling pre-processor capable of fitting into the microphone input path or digital I2S input path of any type of communication device. As an added benefit, traditional and original microphone input circuitry and components do not need to be changed much.
