AK4124VF - 192kHz 24-Bit Async SRC | AKM | Audio
MPN: AK4124VF ✗ انتهى عمره الإنتاجيAK4124VF نظرة عامة
An asynchronous sample-rate converter is an audio interface IC that converts a digital audio stream running at one clock rate into a stream operating at another rate. In the broader component hierarchy, the AK4124VF belongs to the family of digital audio converters and interface ICs used within professional audio, consumer audio, and networked-media equipment. Unlike a simple fixed-ratio clock divider, an asynchronous SRC estimates the input-to-output timing relationship and resamples the incoming PCM data. This capability is useful when the source and destination do not share a common, continuously synchronized master clock.
The AK4124VF's principal verified features are a maximum sampling frequency of 192 kHz and 24-bit audio resolution. These figures suit high-resolution digital-audio systems where format conversion, clock-domain bridging, or asynchronous playback is required. The product is categorized specifically as an Audio Channel IC rather than a general-purpose codec, and its asynchronous SRC architecture distinguishes it from parts that merely accept one fixed sample-rate relationship. Exact dynamic-range, distortion, attenuation, channel-count, clocking, and voltage specifications were not present in the supplied source data and therefore require confirmation from the manufacturer datasheet before design release.
The supplied distributor records also establish important procurement details. DigiKey identifies AK4124VF as an Asahi Kasei Microdevices/AKM audio-channel component and presents pricing and availability data, while Octopart states that two distributors participate in price comparison. GlobalSpec identifies the component as obsolete, categorized under Integrated Circuits, and lists EAR99 export-control classification. Its moisture-sensitivity designation is MSL 1, described as unlimited, while the package quantity is 1000 units on a reel. These verified attributes should be considered alongside the obsolete lifecycle status when planning new production.
Potential applications include professional digital-audio equipment, asynchronous audio-clock bridging, high-resolution playback systems, digital mixers, and interface paths requiring conversion between 44.1 kHz, 48 kHz, 96 kHz, or 192 kHz streams. The 24-bit format supports high-resolution processing, and the 192 kHz ceiling allows the device to be used where source material exceeds conventional CD-rate sampling. System designers must still verify supported input and output rate combinations, supported data formats, required master-clock relationships, and digital I/O voltage levels against the manufacturer documentation.
The principal design consideration is lifecycle risk. Because AK4124VF is reported as obsolete, new designs should not be committed without confirming long-term supply, authorized-channel traceability, and whether an approved second source exists. PCB designers should also reserve space and maintain a documented footprint based on the verified manufacturer package drawing rather than inferred dimensions. Input and output digital interfaces must be checked for voltage compatibility, and the power, ground, clock, and decoupling requirements must follow the manufacturer's reference circuit.
This page consolidates verified distributor lifecycle, packaging, classification, and high-level conversion information, then adds engineering-focused application guidance and selection criteria. It also distinguishes verified facts from missing electrical details: unsupported numerical specifications are not inferred, and production decisions should use the manufacturer datasheet plus authorized-distributor availability records.

التطبيقات النموذجية
AK4124VF مناسب لـ 6 التطبيقs: Professional Digital Audio Conversion, Asynchronous Clock-Domain Bridging, High-Resolution Audio Playback, Digital Mixer and Studio Signal Routing, Networked Audio and Media Equipment, Audio Interface Maintenance and Obsolescence Support.
Professional Digital Audio Conversion
The AK4124VF fits a professional digital-audio interface requiring asynchronous sample-rate conversion at up to 192 kHz with 24-bit data. It can be positioned between source and destination digital-audio domains when their clocks are not continuously synchronized, allowing PCM audio to be transferred without requiring a shared master clock. The 192 kHz ceiling supports high-resolution production workflows, while 24-bit operation preserves the source format resolution. Before hardware use, engineers must verify supported input and output rates, data-word alignment, clocking, latency, and signal levels against the manufacturer datasheet. It is best suited to sustaining an existing qualified design because GlobalSpec reports the AK4124VF as obsolete.
موصى به
Asynchronous Clock-Domain Bridging
The AK4124VF is applicable where a digital-audio source and destination operate from independent clocks and require an asynchronous sampling-rate conversion stage. Its verified high-performance asynchronous SRC architecture supports up to 192 kHz and 24-bit audio, making it relevant to bridges, playback chains, and studio systems handling multiple clock domains. The implementation must account for the SRC's clock requirements and permitted format combinations, which are not available in the supplied source records. PCB layout should isolate digital clock and data signals and provide manufacturer-directed decoupling. Since the component is obsolete, any new clock-bridge design should include a documented lifecycle review and qualification of a maintained alternative before production commitment.
موصى به
High-Resolution Audio Playback
The 192 kHz maximum sampling frequency and 24-bit resolution make the AK4124VF relevant to high-resolution audio playback systems that must reconcile source material with a different playback-rate domain. The converter can occupy the digital path before a DAC when the source and DAC do not share a continuously usable clock relationship. However, the supplied data does not confirm jitter tolerance, latency, output word length, or supported rate pairs, so those values must be obtained from the AK4124 datasheet. Engineers should verify the complete source-to-DAC format path and measure clock margin in prototypes. The obsolete lifecycle status makes this best suited to maintaining established equipment rather than creating a new long-life consumer platform without supply protection.
موصى به
Digital Mixer and Studio Signal Routing
A digital mixer or studio routing system can use the AK4124VF to convert asynchronous digital-audio streams before they enter a processing matrix. The verified 24-bit format preserves high-resolution sample data, while the 192 kHz capability supports studio material operating beyond conventional 48 kHz rates. The device's exact role depends on clock domains, supported data formats, and whether conversion is required on one or multiple channels; those details are not present in the verified snippets. Designers should compare the AK4124VF's manufacturer-specified interface with the mixer's required word length and framing. PCB signal-integrity review should cover clock routing, return paths, and grounding. Because the part is obsolete, sustaining applications should preserve the original footprint only after checking the manufacturer package drawing.
موصى به
Networked Audio and Media Equipment
The AK4124VF may be used in networked-audio equipment when received or transmitted PCM streams use asynchronous timing relative to the local audio-processing clock. Its 192 kHz, 24-bit asynchronous SRC function can bridge that timing difference in a digital path without moving the data through an analog stage. A practical implementation still requires confirmation of supported rates, interface voltage, clock-frequency limits, and system latency from the manufacturer documentation. Clock jitter and format framing should be evaluated at system level rather than inferred from the converter name. The part's obsolete status requires a supply-risk assessment for new network-audio programs, including traceability and a second-source plan. In established equipment, the existing board layout and clock architecture must be cross-checked before reusing this device.
موصى به
Audio Interface Maintenance and Obsolescence Support
The AK4124VF remains relevant for maintenance of installed professional-audio equipment because the verified records show continued distributor inquiry pages while also identifying the component as obsolete. For a sustaining design, engineers should use the original AK4124 manufacturer datasheet to reproduce pin connections, clocking, supply sequencing, and decoupling, then obtain current inventory from authorized channels. The supplied evidence reports a reel quantity of 1000 units, MSL 1 unlimited floor life, and EAR99 classification, but it does not establish authenticity or date-code condition for any individual reel. Procurement should therefore require inspection, traceability, and storage-history records. This application is specifically for preserving proven behavior, not for designs that require a guaranteed active product roadmap.

ملاحظات التصميم
Do not treat a distributor listing or family resemblance as proof of drop-in compatibility. The verified cross-reference search did not identify a pin-compatible replacement for AK4124VF, and AK4125VF, AK4127VF, AK4136VQ, and AK4137EQ are only related AKM products. Before substituting any candidate, compare the manufacturer package drawings, pin assignments, supported sample-rate pairs, digital interface format, clock requirements, supply voltage, and control behavior. A board-level change or format translation may be required even when the functional description appears similar.
Route the AK4124VF's digital clock, data, and control signals according to the manufacturer reference layout rather than from an inferred package drawing. Keep clock traces short, provide a continuous return path, avoid coupling to analog or high-current switching nodes, and place required bypass capacitors at the supply pins. Because the supplied data does not include the exact pin count or package dimensions, confirm the official AK4124 footprint and exposed-pad requirements before PCB release or footprint substitution.
The input-voltage range, output logic levels, and power dissipation were not available in the verified source data, so supply compatibility must not be assumed. Determine the exact digital-interface voltage domains used by the source and destination devices before connecting the AK4124VF. Validate the manufacturer's recommended supply sequencing and decoupling, and check signal levels for every direction. If the audio interface operates at multiple logic voltages, do not infer level-shift or translation support from the 24-bit, 192 kHz specifications.
The AK4124VF is reported as obsolete, making counterfeit, mixed-reel, and aged inventory risks more important than usual. Purchase only through authorized or otherwise qualified channels, request date codes, lot traceability, inspection results, and storage history, and retain purchase documentation. MSL 1 with unlimited floor life does not establish authenticity or guarantee long-term availability. For maintenance quantities, preserve unopened reels and use a FIFO rotation process; for new designs, obtain written lifecycle assurance and qualify an alternative before committing the PCB.
معلومات الامتثال
GlobalSpec identifies MSL 1 with unlimited floor life and EAR99 export classification. RoHS, REACH, lead-free, halogen-free, and conflict-minerals declarations were not included in the supplied verified data and are therefore recorded as unknown. AEC-Q100 is treated as not applicable because AK4124VF is an audio interface IC rather than an automotive-qualified device in the provided records.
