WM5100 Datasheet | Wolfson Microelectronics

.Data Sheet.co.kr w DESCRIPTION The WM5100 is a highly-integrated low-power audio system with exceptional levels of performance and signal processing capability. Digital effects, noise reduction, speech clarity and Ambient Noise Cancellation (ANC) algorithms are all supported, suitable for a wide variety of mobile and handheld devices. The Wolfson my Zone™ technology supports receive (RX) path and transmit (TX) path noise cancellation. Acoustic Echo Cancellation (AEC) algorithms are also supported. The WM5100 is ideal for mobile telephony applications, providing enhanced voice munication quality for nearend and far-end handset users. The WM5100 digital core provides extensive capability for programmable signal processing algorithms. Equalisation and application-specific filters can be implemented, including digital effects to improve audibility and stereo imaging in small size loudspeakers. Highly flexible digital mixing, including multi-channel sample rate conversion between asynchronous clocking domains, provides usecase flexibility across a broad range of system architectures. Three independent digital audio interfaces are provided, each supporting a wide range of standard audio sample rates. The integrated headphone drivers provide 3 stereo groundreferenced outputs. These can also be configured in mono differential (BTL) configuration. Noise levels as low as 3.2μVRMS provide hi-fi quality output. Speakerphone applications can be supported using the Class D speaker driver or the integrated digital speaker (PDM) interface with an external PDM-input speaker amplifier. The WM5100 supports up to eight analogue or digital microphone inputs. The Wolfson my Zone TM ANC processor implements an enhanced filtering algorithm to consistently deliver the optimum noise cancellation performance using two or more microphone input channels. A smart digital microphone interface provides power regulation, low jitter clock output and decimation filters for digital microphones....
