WM5102 w Audio Hub CODEC with Voice Processor DSP DESCRIPTION FEATURES 1 Audio hub CODEC with integrated voice processor DSP The WM5102 is a highly-integrated low-power audio system for smartphones, tablets and other portable audio Programmable DSP capability for audio processing devices. It combines wideband telephony voice processing Fixed function signal processing functions with a flexible, high-performance audio hub CODEC. - Wind noise, sidetone and other programmable filters The WM5102 digital core provides a powerful combination - Dynamic Range Control, Fully parametric EQs of fixed-function signal processing blocks with a - Tone, Noise, PWM, Haptic control signal generators programmable DSP. These are supported by a fully-flexible, Multi-channel asynchronous sample rate conversion all-digital audio mixing and routing engine with sample rate Integrated 6/7 channel 24-bit hi-fi audio hub CODEC converters, for wide use-case flexibility. The programmable - 6 ADCs, 96dB SNR microphone input (48kHz) DSP supports a range of audio processing software packages (supplied separately) user-programmed solutions - 7 DACs, 113dB SNR headphone playback (48kHz) can also be supported. Fixed-function signal processing Audio inputs blocks include filters, EQ, dynamics processors and sample - Up to 6 analogue or digital microphone inputs rate converters. - Single-ended or differential mic/line inputs A SLIMbus interface supports multi-channel audio paths and Multi-purpose headphone / earpiece / line output drivers host control register access. Multiple sample rates are - 2 stereo output paths supported concurrently via the SLIMbus interface. Three - 29mW into 32 load at 0.1% THD+N further digital audio interfaces are provided, each supporting - 100mW into 32 BTL load at 5% THD+N a wide range of standard audio sample rates and serial interface formats. Automatic sample rate detection enables - 6.5mW typical headphone playback power consumption seamless wideband/narrowband voice call handover. - Pop suppression functions - 2.3V noise floor (A-weighted) RMS Two stereo headphone drivers each provide stereo ground- Mono BTL earpiece output driver referenced or mono BTL outputs, with noise levels as low as 2.3 V for hi-fi quality line or headphone output. The RMS 2 x 2W stereo Class D speaker output drivers CODEC also features stereo 2W Class-D speaker outputs, a - Direct drive of external haptics vibe actuators dedicated BTL earpiece output and PDM for external Two-channel digital speaker (PDM) interface speaker amplifiers. A signal generator for controlling haptics SLIMbus audio and control interface devices is included vibe actuators can connect directly to the Class-D speaker output, or via an external driver on the 3 full digital audio interfaces PDM output interface. All inputs, outputs and system - Standard sample rates from 4kHz up to 192kHz interfaces can function concurrently. - Ultrasonic accessory function support The WM5102 supports up to six microphone inputs, each - TDM support on all AIFs either analogue or PDM digital. Microphone activity - 8 channel input and output on AIF1 detection with interrupt is available. A smart accessory Flexible clocking, derived from MCLKn, BCLKn or SLIMbus interface supports most standard 3.5mm accessories. 2 low-power FLLs support reference clocks down to 32kHz Impedance sensing and measurement is provided for Advanced accessory detection functions external accessory and push-button detection. - Low-power standby mode and configurable wake-up The WM5102 power, clocking and output driver Configurable functions on 5 GPIO pins architectures are all designed to maximise battery life in Integrated LDO regulators and charge pumps voice, music and standby modes. Low-power Sleep is Support for single 1.8V supply operation supported, with configurable wake-up events. The WM5102 is powered from a 1.8V external supply. A separate supply is Small W-CSP package, 0.4mm pitch required for the Class D speaker drivers (typically direct connection to 4.2V battery). APPLICATIONS Two integrated FLLs provide support for a wide range of Smartphones and Multimedia handsets system clock frequencies. The WM5102 is configured using Tablets and Mobile Internet Devices (MID) the I2C, SPI or SLIMbus interfaces. The fully-differential General-purpose low-power audio CODEC hub internal analogue architecture, minimal analogue signal paths and on-chip RF noise filters ensure a very high degree of noise immunity.
