WM5100 product brief w pp, july 2011, rev 1.0 8 description the WM5100 is a low power, high quality audio codec designed to interface with a wide range of processors and digital audio components. the WM5100 incorporates the wolfson myzone? ambient noise cancellation (anc) and additional configurable dsp for audio enhancement algorithms. a high level of mixed-signal integration in a very small footprint makes it ideal for portable applications such as mobile phones. fully differential internal architecture and on-chip rf noise filters ensure a very high degree of noise immunity. the WM5100 digital core provides extensive mixing and processing capabilities for multiple signal paths. the digital core provides parametric equalisation (eq) functions, low-pass / high-pass filters, dynamic range control (drc) and programmable dsp capability. the dsp can support functions such as wind noise, side-tone or other programmable filters, also dynamic range control and compression, or virtual surround sound and other audio enhancements. the adcs and dacs are of hi-fi quality, using a 24-bit low-order oversampling architecture to deliver optimum performance. the wolfson myzone tm ambient noise cancellation (anc) processor within the WM5100 provides the capability to improve the intelligibility of a voice call by using destructive interference to reduce the acoustic energy of the ambient sound. eight digital microphone input channels are available to support advanced multi-microphone applications such as noise reduction. up to eight analogue inputs can be connected, to allow interfacing to microphones or line level audio signals. the WM5100 supports single-ended and differential analogue input connections. six stereo output channels are available to support a wide variety of use cases. the output signal paths comprise analogue headphone drivers, class d loudspeaker drivers and also a four channel digital (pdm) interface suitable for external speaker drivers. all outputs have integrated pop and click suppression features. the headphone output drivers are ground-referenced, powered from an integrated charge pump, enabling high quality, power efficient headphone playback without any requirement for dc blocking capacitors. ground loop feedback is incorporated, providing rejection of noise on the ground connections. a mono mode is available on each of the headphone outputs; this configures the drivers as differential (btl) outputs, suitable for an earpiece or hearing aid coil. the WM5100 provides three audio interfaces in order to provide independent and fully asynchronous connections to multiple processors - typically an application processor, baseband processor and wireless transceiver. each interface supports a number of protocols, including i 2 s, dsp or left justified, and can operate in master or slave modes. pcm operation is supported in the dsp mode. time division multiplexing (tdm) is available to allow multiple devices to stream data simultaneously on the same bus, saving space and power. eight-channel input and output is supported using tdm on aif1. two-channel input and output is supported on aif2 and aif3. signal mixing between audio interfaces is possible. the WM5100 performs stereo full-duplex sample rate conversion between the audio interfaces as required. the audio interfaces aif1, aif2 and aif3 are referenced to dbvdd1, dbvdd2 and dbvdd3 respectively; this provides additional capability to interface between different sub-systems within an application. a flexible clocking arrangement supports a wide variety of external clock references, including clocking derived from the digital audio interface. two integrated frequency locked loop (fll) circuits provide additional flexibility. typical portable system mclk frequencies, and sample rates from 4khz to 768khz are all supported. a low frequency (eg. 32.768khz) clock can also be used as the input reference to the flls, providing further flexibility. the WM5100 uses a standard 2-wire control interface, providing full software control of all features, together with device register readback. it is an ideal partner for a wide range of industry standard microprocessors, controllers and dsps. unused circuitry can be disabled under software control, in order to save power; low leakage currents enable extended standby/off time in portable battery- powered applications. versatile gpio functionality is provided, with support for button/accessory detect inputs, or for clock, system status, or programmable logic level output for control of additional external circuitry. interrupt logic and status readback are supported within this functionality. www.datasheet.co.kr datasheet pdf - http://www..net/
