CS8416-DNZ - 8-Channel 192kHz Audio Receiver | Cirrus Logic
MPN: CS8416-DNZ ✓ نشطCS8416-DNZ نظرة عامة
A digital audio receiver is an interface IC that accepts encoded audio data, identifies the supported transport format, and converts that data into a serial digital-audio stream suitable for a DAC, audio processor, or digital mixing system. Within the broader semiconductor hierarchy, the CS8416 belongs to the digital-audio receiver class, then to interface ICs and signal-chain semiconductors. It is designed for systems requiring multiple digital inputs, channel-status handling, and flexible configuration rather than analog audio amplification.
The CS8416 supports sample rates through 192 kHz and can operate in software-controlled or hardware-controlled configuration. The software mode uses a selectable control port, while hardware mode uses dedicated configuration pins. This flexibility allows the same receiver architecture to serve professional equipment, consumer audio products, and multi-input monitoring systems. The eight-input multiplexer also helps reduce the number of separate receiver devices required in a rack or board with several S/PDIF or AES/EBU sources.
The monolithic CMOS implementation integrates receiver and decoding functions in one device. According to the Cirrus Logic CS8416 datasheet DS578F4, the device receives one of eight stereo pairs of digital-audio data and supports the IEC60958, S/PDIF, EIAJ CP1201, and AES3 standards. The output architecture provides a serial digital-audio port, while control and channel-status functions support practical system implementation.
Typical applications include professional digital mixers, multichannel recording equipment, broadcast consoles, surround-sound processors, digital audio routers, computer-audio interfaces, and consumer receivers with multiple coaxial or optical inputs. The 192 kHz capability also makes the part relevant to high-resolution audio paths, provided that the upstream source, transport wiring, clocking arrangement, and downstream converter support the selected rate.
PCB design should preserve short, controlled-impedance routes from each digital-audio input to the receiver and keep the serial output path away from noisy switching nodes. Grounding and decoupling should follow the layout guidance in the manufacturer datasheet. Verify input levels, supported sampling rates, master-clock requirements, and software configuration before finalizing a multichannel board because those details determine whether a single CS8416 is sufficient.
This page combines the CS8416 interface architecture, protocol support, package information, application guidance, and verified sourcing information. It also distinguishes documented functions from unresolved replacement questions, helping engineers plan receiver selection, board integration, and multi-channel audio routing without treating nonverified equivalents as drop-in devices.

التطبيقات النموذجية
CS8416-DNZ مناسب لـ 6 التطبيقs: Professional Digital Audio Mixer, Digital Audio Router, Broadcast Console, Multichannel Recording System, Surround-Sound Processor, Computer Audio Interface.
Professional Digital Audio Mixer
The CS8416-DNZ fits a professional mixer receiving several stereo digital sources because it accepts eight stereo digital-audio inputs and selects one through an integrated 8:2 multiplexer. This can simplify the input stage by replacing several separate receiver paths while retaining support for IEC60958, S/PDIF, EIAJ CP1201, and AES3 transports. The serial digital-audio output can feed the mixer's processing and conversion stages. With support through 192 kHz, the receiver also accommodates high-resolution studio workflows when the source, clocking, and downstream devices operate at the same rate. The 28-pin QFN package saves board area, although its 5 mm by 5 mm footprint requires careful pad layout and thermal-aware assembly.

Digital Audio Router
CS8416-DNZ is appropriate for a digital-audio router that must accept more sources than its downstream processing path can consume. Eight stereo inputs can be presented to the system, and the 8:2 multiplexer permits selection of one of those channels for the serial output. This arrangement is useful in studio patch systems, recording installations, and broadcast processing chains where incoming streams use compatible digital-audio standards. Because the receiver can operate in software or hardware control mode, it can support a microcontroller-managed router or a simpler pin-configured design. The 192 kHz capability helps preserve high-resolution sources, while the QFN package keeps the receiver compact for multi-channel equipment.

Broadcast Console
The CS8416-DNZ can support a broadcast console receiving stereo digital-audio feeds from studios, effect processors, and transmission equipment. IEC60958 and AES3 compatibility are central to professionally distributed digital audio, while eight stereo inputs provide selection flexibility around a constrained console input bus. The part's 192 kHz maximum sample rate covers high-resolution production paths when supported by the complete signal chain. Software mode is useful when the console controller must configure input routing dynamically, whereas hardware mode can simplify fixed installations. In a dense console, the 28-pin QFN package offers a practical alternative to larger through-hole or leaded packages, provided that assembly and test access are carefully planned.

Multichannel Recording System
CS8416-DNZ is suited to multichannel recording equipment that ingests digital-audio streams from external devices and selects a source for the internal processing chain. Eight stereo inputs allow several synchronized or selectable sources to be connected without duplicating the receiver section. Support for S/PDIF, IEC60958, EIAJ CP1201, and AES3 increases compatibility with studio equipment using different digital-audio conventions. The 192 kHz capability is valuable for high-resolution capture workflows, but all devices in the clock and data path must support the selected rate and channel format. The compact QFN construction helps fit the receiver into rack-mount or desktop recording equipment without consuming the area of multiple discrete receiver devices.

Surround-Sound Processor
CS8416-DNZ can serve as the digital-audio receiver in a surround-sound processor receiving encoded or discrete digital streams. Eight stereo inputs provide capacity for multiple source selections, such as a primary program feed, alternate source, and auxiliary digital-audio paths. Its serial output and configurable control modes allow the processor to route the selected stream into channel decoding, delay, or conversion circuitry. Support through 192 kHz accommodates high-resolution source material when the processor and downstream DACs are designed for it. The receiver does not itself perform surround decoding, so its role must remain clearly separated from the channel-processing and DAC stages. The small QFN footprint supports compact processor boards without relaxing layout or assembly discipline.

Computer Audio Interface
The CS8416-DNZ is relevant to professional computer-audio interfaces that accept multiple digital inputs and present a selected stream to a host or converter section. Its eight stereo inputs can accommodate front-panel, rear-panel, and external source options, while the 8:2 multiplexer consolidates selection into one serial-audio path. Software mode allows a USB controller or embedded processor to configure routing, making the receiver suitable for dynamic desktop and rack interfaces. IEC60958 and AES3 support enables interoperability with professional digital sources. The QFN package suits compact desktop interfaces, but designers should preserve short digital-input routes, provide appropriate termination and coupling according to the datasheet, and verify host-clock requirements before finalizing the board.

ملاحظات التصميم
Route each S/PDIF, AES3, or IEC60958 input using the topology recommended in the CS8416 datasheet, including the required input coupling and termination arrangement. Keep these digital-audio traces short, keep the ground reference continuous, and avoid routing them parallel to switching-node paths. The 28-pin QFN footprint also requires correct exposed-pad geometry, so use the manufacturer land-pattern dimensions rather than a generic QFN footprint.
Keep the serial digital-audio output path away from analog clocks, switching regulators, and high-current return paths, and provide a continuous reference plane beneath the route. If the receiver feeds a long cable, test the source-to-receiver channel separately with suitable instrumentation and verify the interconnect standard. Configuration pins and serial-control traces should be kept away from the audio inputs to reduce coupling from control activity.
Do not assume that every CS8416 ordering suffix is interchangeable. The family includes multiple package and grade configurations, while CS8416-DNZ is the 28-pin 5 mm by 5 mm QFN version. Before substituting a family member, compare the exact package drawing, pin-description table, temperature range, supply rating, and control interface. Also confirm that the upstream source and downstream converter support the same sample rate and digital-audio format.
Treat the 192 kHz figure as a maximum supported rate, not a guarantee that every source will operate correctly at that rate. The complete path must support the selected frequency and must share compatible clocking. Validate software-mode initialization, hardware-mode strap settings, channel-status handling, and output format with the system controller before releasing production hardware.
