Audio Codec 6ADC /7 DAC 24-Bit 137-Pin WCSP T/R

The WM5102ECS/R 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 WM5102ECS/R 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 groundreferenced 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 WM5102ECS/R 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 WM5102ECS/R 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 WM5102ECS/R 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.
