WM5102
Audio Hub CODEC with Voice Processor DSP
DESCRIPTION
The WM5102[1] is a highly-integrated low-power audio
system for smartphones, tablets and other portable audio
devices. It combines wideband telephony voice processing
with a flexible, high-performance audio hub CODEC.
The WM5102 digital core provides a powerful combination
of fixed-function signal processing blocks with a
programmable DSP. These are supported by a fully-flexible,
all-digital audio mixing and routing engine with sample rate
converters, for wide use-case flexibility. The programmable
DSP supports a range of audio processing software
packages (supplied separately); user-programmed solutions
can also be supported. Fixed-function signal processing
blocks include filters, EQ, dynamics processors and sample
rate converters.
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.
Two stereo headphone drivers each provide stereo ground-
referenced or mono BTL outputs, with noise levels as low as
2.3μVRMS for hi-fi quality line or headphone output. The
CODEC also features stereo 2W Class-D speaker outputs, a
dedicated BTL earpiece output and PDM for external
speaker amplifiers. A signal generator for controlling haptics
devices is included; vibe actuators can connect directly to
the Class-D speaker output, or via an external driver on the
PDM output interface. All inputs, outputs and system
interfaces can function concurrently.
The WM5102 supports up to six microphone inputs, each
either analogue or PDM digital. 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 WM5102 power, clocking and output driver
architectures are all designed to maximise battery life in
voice, music and standby modes. Low-power ‘Sleep’ is
supported, with configurable wake-up events. The WM5102
is powered from a 1.8V external supply. A separate supply is
required for the Class D speaker drivers (typically direct
connection to 4.2V battery).
Two integrated FLLs provide support for a wide range of
system clock frequencies. The WM5102 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.
