WM8569SEDS/V - 24-Bit 192kHz Stereo Audio Codec | Cirrus Logic
Référence : WM8569SEDS/V ✓ ActifWM8569SEDS/V Présentation
An audio codec is a mixed-signal semiconductor that converts between digital audio data and analog audio signals. Within the signal-chain hierarchy, the WM8569SEDS/V combines an audio ADC, a stereo multi-bit sigma-delta DAC, digital interpolation filters, volume control, and a digital control interface. This integration allows a host processor to play and record stereo audio through one compact device instead of using separate converter packages.
The principal performance parameters are 24-bit resolution, sampling rates from 8 kHz to 192 kHz, two ADC channels, and two DAC channels. Digital audio input word lengths can be configured from 16 to 24 bits. The separate ADC and DAC clocking architecture is particularly useful in consumer equipment where the system clock supplied to the capture and playback paths is not identical.
The WM8569 uses multi-bit sigma-delta conversion for its stereo DAC, with oversampling and digital interpolation filtering in the signal path. The device also includes volume control and is identified by the manufacturer as suitable for DVD, PVR, LCD-TV, and automotive audio systems. Digital configuration is performed through a serial control interface, allowing software-defined gain, routing, and operating-mode settings.
Typical deployments include DVD and personal-video-recorder audio paths, LCD television sound systems, automotive head-unit audio, and other multimedia products that require simultaneous stereo recording and playback. Independent ADC and DAC clocks are valuable when the source device records at a different rate from the playback stream. The 192 kHz capability also supports high-resolution audio processing pipelines.
When laying out the circuit, treat analog input, analog output, digital interface, and supply connections as separate functional groups. Follow the pin-description table and recommended application circuit in the manufacturer datasheet for decoupling, grounding, and analog routing. Confirm the digital audio word length, master-clock configuration, and serial-interface mode in firmware before enabling the playback and capture paths.

Applications typiques
WM8569SEDS/V convient pour 6 applications: DVD Player Audio Path, Personal Video Recorder Audio, LCD Television Sound System, Automotive Multimedia Head Unit, High-Resolution Digital Audio Playback, Stereo Recording and Playback Interface.
DVD Player Audio Path
The WM8569SEDS/V fits a DVD audio path because it combines stereo ADC and DAC functions, accepts 16-bit to 24-bit digital input, and reaches a maximum sampling rate of 192 kHz. The SPI control interface allows the host to configure volume, routing, and conversion behavior during system initialization. Its multi-bit sigma-delta DAC with digital interpolation filtering provides the playback stage while the ADC path supports additional capture functions. Verify supply levels, clock topology, and analog-output integration against the manufacturer application circuit before laying out the board.
Recommandé
Personal Video Recorder Audio
The WM8569SEDS/V is appropriate for a PVR that both records and reproduces stereo audio because it integrates two ADC channels and two DAC channels. Independent ADC and DAC clocking supports systems in which the capture stream and playback stream do not share the same sampling rate. The 24-bit resolution accommodates high-resolution source material, while the SPI control interface keeps host configuration compact and software-driven. Confirm the required master-clock sources and supported serial-audio formats in the datasheet before finalizing the clock tree.
Recommandé
LCD Television Sound System
Cirrus Logic specifically identifies LCD-TV systems as a target application for the WM8569SEDS/V. The integrated stereo converter supports audio playback and capture in a compact design, while independent ADC and DAC clocks accommodate differing internal rates. The 192 kHz ceiling provides headroom for high-resolution processing, although the actual operating rate must match the source and downstream DAC architecture. Board planning should isolate analog output routing from digital interface traces and follow the recommended grounding and decoupling arrangement.
Recommandé
Automotive Multimedia Head Unit
The WM8569SEDS/V is identified by the manufacturer for automotive audio applications, combining two stereo ADCs, two stereo DACs, and independent converter clocking in one package. That integration can simplify a head unit that handles radio, navigation prompts, media playback, and recording through a common audio subsystem. Before adopting the part, verify the suffix-specific temperature rating, automotive qualification status, supply range, and EMC-related board recommendations in the manufacturer documentation. Firmware must also confirm clock, word-length, and serial-interface settings during startup.
Recommandé
High-Resolution Digital Audio Playback
The WM8569SEDS/V suits digital playback designs that require 24-bit conversion and sample rates as high as 192 kHz. Its stereo multi-bit sigma-delta DAC, oversampling architecture, and digital interpolation filters form the output signal path, while volume control is integrated into the device. The SPI control path allows the host processor to configure operating conditions during initialization. Select this device when integrated playback and capture are both valuable; use a dedicated DAC such as PCM5122PWR when only the playback function and higher-end output architecture are required.
Recommandé
Stereo Recording and Playback Interface
Independent ADC and DAC clocking makes the WM8569SEDS/V useful in equipment that records and plays audio through different clock domains. The device supports 24-bit resolution, 16-bit to 24-bit digital input word lengths, and sampling rates from 8 kHz to 192 kHz within one stereo codec. This allows a host processor to manage capture and playback through a common SPI configuration path. In implementation, validate each converter's supported clocking mode and avoid assuming that both sides may use arbitrary or asynchronous master clocks.

Notes de conception
Keep analog input and output routing away from the SPI and digital audio interface traces. Place the required bypass capacitors at their associated supply pins and follow the component placement shown in the manufacturer application circuit. Sensitive analog signals should have short return paths to the device ground reference rather than sharing wide digital-return geometry.
Treat the clock and data connections as a matched digital interface. Route the master clock and serial audio signals away from analog outputs, minimize stub branches, and provide a continuous ground reference beneath the interface section. Confirm the supported clock ratio, edge relationships, and signal levels in the datasheet before finalizing the source-device connections.
Do not assume that the V and RV ordering suffixes are interchangeable. The RV listing specifies a -25°C to +85°C operating range, whereas the V suffix temperature range is not stated in the available catalog data. Confirm the suffix-specific temperature rating, production status, and qualification requirements with the manufacturer before approving a substitution.
Informations de conformité
