WM5110
Low Power Audio System with Wolfson myZone™
Ambient Noise Cancellation and Echo Cancellation
DESCRIPTION
The WM5110 is a highly-integrated low-power audio system
for smartphones, tablets and other portable audio devices. It
combines an advanced DSP feature set with a flexible, high-
performance audio hub CODEC.
The WM5110 digital core combines a quad-core, 600MMAC
DSP system with a variety of power-efficient fixed-function
audio processing blocks. The programmable DSP cores
support advanced audio features, including multi-mic
wideband noise reduction and beamforming, high-
performance acoustic echo cancellation (AEC), stereo
ambient noise cancellation (ANC), speech enhancement,
advanced media enhancement, and many more. The DSP
cores are supported by a fully-flexible, all-digital mixing and
routing engine with sample rate converters, for wide use-
case flexibility.
A SLIMbus interface supports multi-channel audio paths and
host control register access. Multiple sample rates are
supported concurrently via the SLIMbus interface. Three
further digital audio interfaces are provided, each supporting
a wide range of standard audio sample rates and serial
interface formats. Automatic sample rate detection enables
seamless wideband/narrowband voice call handover.
Three stereo headphone drivers each provide stereo
ground-referenced or mono BTL outputs. 110dB SNR, and
noise levels as low as 2μVRMS, offer hi-fi quality line or
headphone output. High power, high-quality speaker output
is provided by a stereo pair of 2W Class-D speaker
amplifiers. Four channels of stereo PDM output are
provided, for connection to external amplifiers.
The WM5110 supports up to eight microphone inputs, (up to
six analogue, or up to eight PDM digital, or combinations of
each). Microphone activity detection with interrupt is
available. A smart accessory interface supports most
standard 3.5mm accessories. Impedance sensing and
measurement is provided for external accessory and push-
button detection.
The WM5110 power, clocking and output driver
architectures are all designed to maximise battery life in
voice, music and standby modes. The chip can be powered
from a 1.8V external supply. (For full device functionality, a
1.2V digital core supply and a 4.2V Class D speaker driver
supply are recommended.)
Two integrated FLLs provide support for a wide range of
system clock frequencies. The WM5110 is configured using
the I2C, SPI or SLIMbus interfaces. The fully-differential
internal analogue architecture, minimal analogue signal
paths and on-chip RF noise filters ensure a very high degree
of noise immunity.
