WM5100
Low Power Audio System with Wolfson myZone™
Ambient Noise Cancellation and Echo Cancellation
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 myZone™ 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 communication quality for near-
end 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 use-
case 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 ground-
referenced 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 myZoneTM 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.
Microphone activity detection with interrupt is available.
Impedance sensing and measurement is provided for
external accessory and push-button detection.
The WM5100 is powered from a 1.8V external supply. A
supply is also required for the Class D speaker drivers
(typically 4.2V). Two integrated FLLs provide support for a
wide range of system clock frequencies. The WM5100 is
configured using a standard 2-wire serial control interface.
Fully differential internal architecture and on-chip RF noise
filters ensure a very high degree of noise immunity.
