WM8805GEDS/V 8:1 Digital Audio Transceiver | Cirrus Logic
部品番号: WM8805GEDS/V ✓ 生産中WM8805GEDS/V 概要
A digital audio interface transceiver is an interface IC that converts and routes digital audio signals between compatible serial interfaces while adding clock-recovery or synthesis functions. The WM8805GEDS/V belongs to the digital audio transceiver category, a subtype of audio interface IC and, more broadly, interface and signal-conditioning semiconductors. Its integrated PLL supports systems that need a stable digital timing reference for multichannel digital-audio reception or transmission.
The principal verified features of the WM8805GEDS/V include eight receive channels, one transmit channel, a maximum sampling rate of 192 kSPS, and a 2.7 V to 3.6 V supply-voltage range. The single-transmitter, multichannel-receiver arrangement allows a product to accept several digital-audio sources while retaining an S/PDIF transmission path. Operating from 3.3 V makes the device suitable for low-voltage consumer audio equipment, provided the host circuitry observes the documented voltage and signal limits.
The device is available in a 28-pin SSOP with a stated width of 5.30 mm. This surface-mount package is suitable for automated PCB assembly, although its lead pitch and thermal behavior require the dimensions and land pattern in the manufacturer datasheet. The verified operating-temperature range is -40 °C to +85 °C, supporting industrial-temperature consumer and embedded audio equipment when the surrounding system is designed for the same environmental range.
Typical applications include multichannel S/PDIF receivers, digital audio recording equipment, home-theater and set-top-box audio paths, active speakers, and soundbar systems. The eight-channel receiver can simplify systems that need to monitor or route multiple digital-audio inputs, while the one-channel transmitter supports clocked output to another digital-audio device. Exact routing, channel allocation, and master-clock requirements must be established from the manufacturer datasheet.
Designers should verify the digital-audio input amplitude, sampling-rate support, PLL configuration, and clock topology before laying out the PCB. The SSOP footprint should be checked against the official drawing rather than inferred solely from the 28-pin description. Decoupling and exposed interface behavior are not quantified in the supplied source data, so component selection and layout values require confirmation from the manufacturer documentation.
This product record consolidates verified distributor specifications, pricing, package information, source links, and selection guidance. It also distinguishes verified functions from parameters that still require datasheet confirmation, helping engineers assess the WM8805GEDS/V without confusing similar digital-audio transceiver variants.

主な用途
WM8805GEDS/V の用途: 6 件s: Multichannel S/PDIF Receiver, Digital Audio Recording Equipment, Home-Theater Audio Processor, Soundbar and Active-Speaker System, Digital-Audio Router and Selector, Set-Top-Box Digital Audio Path.
Multichannel S/PDIF Receiver
The WM8805GEDS/V fits a multichannel S/PDIF receiver because it accepts eight digital-audio receive channels and operates at up to 192 kSPS. The integrated PLL supports systems requiring a stable timing relationship between received audio streams and the host digital-audio processor. Place the transceiver beside the S/PDIF input connectors and route its serial outputs to the relevant DSP or codec. Because the supplied data does not specify input sensitivity, jitter limits, or recommended termination, those values must come from the manufacturer datasheet. The 2.7 V to 3.6 V operating range is compatible with a conventional 3.3 V audio-processing domain.
おすすめ
Digital Audio Recording Equipment
The WM8805GEDS/V can serve as the multichannel digital-audio intake device in professional or consumer recording equipment that accepts S/PDIF sources. Eight receive channels provide a practical way to monitor or route several digital inputs, while the single transmit channel supports clocked digital output. Sampling rates can reach 192 kSPS, supporting high-resolution workflows when the recorder, clock source, and storage path also support that rate. The transceiver should be clocked according to the manufacturer PLL configuration, and its digital outputs must be interfaced with appropriate impedance-controlled PCB routing to preserve signal integrity.
おすすめ
Home-Theater Audio Processor
The WM8805GEDS/V is suitable for a home-theater processor that must combine several digital-audio inputs and provide a synchronized S/PDIF output. Its eight receive channels can reduce the number of separate input-interface devices, while the integrated PLL helps establish the timing required between source streams and the processing architecture. Operation across 2.7 V to 3.6 V supports low-voltage digital implementation. In a home-theater design, preserve the transceiver's recommended trace geometry, keep high-speed digital traces short, and verify grounding and return paths under the exact sampling mode selected by the system firmware.
おすすめ
Soundbar and Active-Speaker System
The WM8805GEDS/V can be used in a soundbar or active-speaker controller that receives multiple digital-audio streams and forwards one synchronized output. The eight-to-one channel arrangement allows a single package to manage more input streams than it transmits, while operation up to 192 kSPS supports high-resolution source formats. The 28-pin SSOP is suitable for automated assembly, but its footprint must be checked carefully against the official land pattern. Because the verified information does not state input impedance, output drive strength, or jitter limits, these parameters should be validated before selecting passive networks or designing long board-level digital routes.
おすすめ
Digital-Audio Router and Selector
The WM8805GEDS/V is appropriate for a digital-audio router that receives multiple S/PDIF streams, selects or monitors them, and returns a clocked output to the next stage. Eight receive channels provide flexibility for source selection, and the internal PLL can support synchronization required by a digital mixer or codec. The supported 2.7 V to 3.6 V supply range makes it compatible with many 3.3 V systems. Implement channel routing in firmware or surrounding logic after confirming the documented channel maps, error handling, and master-clock options in the manufacturer datasheet, since those details are not included in the supplied distributor summaries.
おすすめ
Set-Top-Box Digital Audio Path
The WM8805GEDS/V can support a set-top-box or television audio path that receives several encoded digital-audio streams and supplies one digital output to an amplifier or processor. Its eight receive channels and 192 kSPS capability accommodate high-resolution streams, while the 2.7 V to 3.6 V range is compatible with typical 3.3 V logic. Place the device close to the input routing network, maintain continuous reference planes beneath high-speed traces, and confirm the PLL configuration for each source format. The verified data does not identify supported subframe formats, so system-level interoperability requires review of the full manufacturer document.

設計ノート
Route S/PDIF data and clock signals as controlled-impedance traces with continuous ground references. Keep the transceiver close to the input connectors and the associated termination or protection network, and avoid routing high-speed digital signals beneath noisy power-converter stages. The verified source does not provide differential impedance, trace-length, or isolation guidance, so use the manufacturer layout recommendations for the selected operating mode.
Design the 3.3 V supply path for the documented 2.7 V to 3.6 V operating range and place local bypass capacitors at the device supply pins. Values and stability requirements are not present in the supplied web data and must be taken from the manufacturer datasheet. Avoid long shared supply branches between the transceiver and digital processors so switching currents from the processor do not modulate the audio-interface supply.
Do not treat WM8805GEDS, WM8805GEDS/V, and WM8805GEDS/RV as automatically interchangeable merely because their names are similar. Confirm the ordering table, package marking, reel configuration, pin table, PLL setup, and exposed test requirements. A suffix can distinguish delivery or customer-specific ordering information without changing the core function, but only the manufacturer document can establish that distinction.
コンプライアンス情報
The supplied verified data contains no explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declaration. AEC-Q100 is not applicable because the product is a consumer-mode audio interface IC rather than an explicitly automotive-qualified device.
