AK4136VQ 概述
A digital sample rate converter, or SRC, is an interface IC that resamples and filters digital audio between clocks with different frequencies. In the product hierarchy, a SRC belongs to digital audio signal-processing ICs and supports audio converters, receivers, network-audio equipment, and test systems. The AK4136 is particularly useful when a transmitter or player uses a different clock domain from the audio source.
The AK4136 supports two channels, 32-bit audio processing, and input and output sample rates spanning 8kHz through 384kHz. According to the manufacturer datasheet, its internal oscillator means that external master clocks are not required for asynchronous conversion. This can reduce clock-tree complexity, although the converter still requires correct power, ground, digital-interface, and signal-integrity implementation.
The 32-bit format and 384kHz maximum rate suit high-resolution audio paths, studio equipment, broadcast infrastructure, digital audio workstations, and consumer systems that need format or clock-domain adaptation. A practical design must still account for required input and output formats, supported clock configurations, filter behavior, grounding, decoupling, and signal routing; those details must be checked in the complete manufacturer documentation.
The principal design consideration is integration. The AK4136VQ can simplify systems where input and output rates are unrelated because its internal oscillator supports asynchronous operation. This avoids one external master-clock source, but it does not eliminate the need for stable local supplies, short digital traces, controlled return paths, and verification of the converter configuration during startup.
This page consolidates the verified manufacturer datasheet, distributor availability, package information, technical search context, and practical engineering guidance. It intentionally avoids asserting electrical, pin, lifecycle, or drop-in replacement details that were not present in the supplied source data.

典型应用
AK4136VQ 适用于 6 应用s: High-Resolution Asynchronous Audio Interface, Professional Audio Equipment, Digital Audio Workstation Routing, Broadcast and Network Audio Infrastructure, Consumer High-Resolution Audio, Digital Audio Test and Measurement.
High-Resolution Asynchronous Audio Interface
The AK4136VQ fits an asynchronous clock-domain boundary between digital audio sources operating from 8kHz to 384kHz. Its 2-channel architecture handles stereo data, while 32-bit processing targets high-resolution formats. The internal oscillator removes the documented need for an external master clock, which can simplify the surrounding clock tree when source and destination clocks are unrelated. The trade-off is that asynchronous conversion must still be configured correctly and validated for the exact digital interface used by the audio system.
推荐
Professional Audio Equipment
The AK4136VQ can support clock adaptation in professional audio equipment that accepts high-resolution stereo digital streams and may operate from clocks independent of the source. Its maximum rate of 384kHz and 32-bit format accommodate demanding audio paths, while the internal oscillator simplifies asynchronous operation. System designers should verify supported data/clock formats and confirm channel performance against the complete manufacturer documentation before using the converter in studio signal chains.
推荐
Digital Audio Workstation Routing
A digital audio workstation may need to bridge stereo streams running at unrelated sample rates, especially when external equipment and internal converters use independent clock domains. The AK4136VQ's documented 8kHz-to-384kHz input and output range covers common high-resolution operating points, and its internal oscillator supports asynchronous conversion without an external master clock. Engineers must account for digital-interface timing, supported word formats, ground references, and converter initialization when routing signals through the device.
推荐
Broadcast and Network Audio Infrastructure
Broadcast and network-audio equipment may need to adapt stereo digital audio whose source and destination sample-rate clocks differ across routing, processing, and transmission stages. The AK4136VQ supports documented input and output rates from 8kHz to 384kHz, 32-bit processing, and asynchronous operation through its internal oscillator. Its suitability still depends on the required electrical interface, synchronization behavior, latency constraints, and channel specifications that must be checked in the complete datasheet.
推荐
Consumer High-Resolution Audio
The AK4136VQ can serve as the asynchronous sample-rate conversion stage in a high-resolution consumer audio product that accepts digital input and feeds a downstream stereo DAC. Its 32-bit processing and rates up to 384kHz align with premium audio use cases, while the internal oscillator reduces the need for a shared external master clock. Board-level implementation must preserve short digital routes, stable supplies, clean grounding, and compatibility with the chosen DAC input format.
推荐
Digital Audio Test and Measurement
Test equipment can use the AK4136VQ to present converted digital audio at a selected output sample rate without relying on the source's master clock. The 8kHz-to-384kHz range and 2-channel architecture are useful for exercising stereo digital interfaces across common audio rates, and the internal oscillator supports asynchronous test configurations. Calibration, expected resampling behavior, supported test patterns, and measurement latency should be established from the manufacturer's documentation and the surrounding test architecture.

- Compact 48-LQFP integration （对比 Larger-package or functionally similar audio converter)
设计说明
Treat every digital audio interface as a clocked, high-speed signal path. Keep input, output, clock, and frame-sync traces short and route them over a continuous ground reference. The supplied data does not specify I/O voltage levels or timing margins, so engineers must obtain those limits from the complete manufacturer datasheet before selecting terminations, voltage translators, or topology.
Use the manufacturer's recommended supply and decoupling configuration exactly, because the verified excerpt confirms the functional architecture but does not provide the AK4136VQ supply-voltage value or external-component table. Place required bypass capacitors at the associated power pins with short ground returns. Do not infer voltage compatibility from another AKM audio IC, and verify startup limits before connecting to non-3.3V digital audio rails.
Do not treat a functionally similar AKM codec or DAC as a drop-in replacement. The AK4136VQ is specifically identified as a 2-channel asynchronous digital SRC with an internal oscillator in a 48-LQFP package. Before substitution, verify every pin, supply rail, interface mode, sample-rate combination, control-register behavior, and package footprint; AK4490x and AK4551 are not verified equivalents.
Separate asynchronous input and output clock domains as required by the final interface implementation, while maintaining a low-impedance common ground. Avoid routing digital audio signals beneath potential switching-noise sources and keep unused-pin handling consistent with the official pinout. Because no complete pin map was present in the verified excerpts, do not assign grounds, test points, or no-connect pins without consulting the manufacturer PDF.
合规信息
No explicit compliance statements were included in the supplied AK4136VQ sources. AEC-Q100 status is unknown rather than not_applicable because no qualification statement was provided.
