CS8411-CP Digital Audio Receiver | 256x Fs | Cirrus Logic
N.º da peça: CS8411-CP ✓ AtivoCS8411-CP Visão geral
A digital audio interface receiver is an interface IC that reconstructs timing and synchronization from a serial digital-audio stream. In the signal-chain hierarchy, a receiver belongs to the digital-audio interface family, connects a physical digital transmission to a clocked audio system, and forms part of the broader interface-IC and semiconductor categories. Its principal function is to recover the transmitted clock and provide synchronized timing for downstream audio-processing circuitry.
The CS8411 family combines a monolithic CMOS implementation, low-jitter on-chip clock recovery, and a 256x Fs output-clock capability. These features make the device suitable for digital-audio equipment that needs a stable recovered or divided clock rather than merely decoded audio data. The -CP ordering code identifies the listed 28-pin PDIP package, allowing the part to be used in designs that support a through-hole digital-audio receiver footprint.
The receiver architecture is intended for serial digital-audio links using AES/EBU, IEC 958, S/PDIF, or EIAJ CP-340 signaling. Clock recovery is particularly important when the source and receiving circuitry do not share a common low-jitter reference clock. The 256x Fs output clock provides a higher-frequency timing reference derived from the received stream, which can support downstream clocking, conversion, or synchronization functions.
Typical applications include professional digital-audio equipment, consumer S/PDIF receivers, digital mixers, audio converters, recording-system clocking, and equipment interfaces that accept a digital-audio transmission. In these systems, the CS8411-CP can receive the serial stream, recover timing, and expose a predictable clock relationship to the surrounding audio architecture.
Designers should verify the complete electrical limits, pin assignment, and application circuit against the Cirrus Logic datasheet before layout. PCB placement should minimize digital-clock and serial-data trace exposure to analog or high-current power paths. Decoupling and input-termination requirements must follow the manufacturer recommendations for the selected source impedance and digital-audio topology.
This page consolidates the confirmed interface standards, 256x Fs clock output, CMOS implementation, package information, sourcing path, and engineering guidance for CS8411-CP. It also distinguishes verified device attributes from electrical details that require confirmation in the original manufacturer documentation.

Aplicações típicas
CS8411-CP é adequado para 6 aplicaçãos: Professional Digital Audio Receiver, S/PDIF Consumer Audio Interface, Digital Audio Converter Clocking, Digital Mixer Input Module, Recording System Audio Interface, Synchronized Audio Equipment.
Professional Digital Audio Receiver
The CS8411-CP fits a professional digital-audio input stage that accepts AES/EBU or IEC 958 signals and requires recovered timing for the processing chain. Its monolithic CMOS receiver architecture performs clock and synchronization recovery directly from the serial stream, while the 256x Fs output clock provides a useful reference for downstream converters and control logic. The 28-pin PDIP format also suits equipment layouts that use through-hole construction. Implement the input path around the manufacturer application circuit, paying particular attention to source-impedance matching, connector return paths, and isolation between the digital clock domain and sensitive analog stages.
Recomendado
S/PDIF Consumer Audio Interface
The CS8411-CP is appropriate for an S/PDIF input block in consumer and professional audio products because S/PDIF is one of the explicitly supported interfaces. It receives the serial stream, recovers the associated clock and synchronization information, and presents a 256x Fs output clock for downstream digital audio logic. This is valuable when the product does not use the incoming stream as a direct master clock or when a consistent high-rate timing reference is required. Preserve the balanced or unbalanced topology dictated by the source, keep return paths continuous, and validate eye margin at the receiver after cables and connectors are included.
Recomendado
Digital Audio Converter Clocking
A digital converter subsystem can use the CS8411-CP to recover a usable timing reference from an external digital-audio link. The 256x Fs output clock provides a defined multiple of the received sample rate, allowing downstream clocking and conversion logic to operate without sharing the transmitter's original master clock. This arrangement is useful in studio equipment, converters, and synchronized audio systems that accept an external digital source. The implementation must account for jitter performance, local clock distribution, grounding, and the exact relationship between the recovered output and the received audio data. Use short clock routes and isolate high-current switching nodes from the receiver.
Recomendado
Digital Mixer Input Module
The CS8411-CP fits a digital mixer input module that receives AES/EBU, IEC 958, or S/PDIF audio and must distribute recovered timing to multiple processing channels. Its on-chip clock recovery removes the need to assume a shared master clock with the transmitting equipment, while the 256x Fs output supplies a common local timing reference. The 28-pin PDIP package is particularly practical for modular or prototype mixer boards that use through-hole assembly. Keep the serial-data route away from motor-control and display power circuitry, provide local decoupling, and confirm that the recovered clock remains usable across all supported sample rates and source jitter conditions.
Recomendado
Recording System Audio Interface
The CS8411-CP can serve as the digital-audio input receiver in a recording system that receives a clocked stream from an external studio, workstation, or master clock source. Because the receiver recovers clock and synchronization information from the transmitted data, the interface can operate without a separate physical master-clock connection. The 256x Fs output clock supports downstream conversion and processing timing, provided the system honors its defined sample-rate relationship. Use the manufacturer input network and pin assignments, maintain a continuous ground reference through the digital cable, and test receiver margin with the actual cable length, connector, source voltage, and termination arrangement.
Recomendado
Synchronized Audio Equipment
The CS8411-CP is useful in synchronized audio equipment that accepts an external digital-audio stream and requires a locally recovered clock. On-chip low-jitter clock recovery and the 256x Fs output support systems that need a predictable timing reference downstream of the receiver. The design is suitable for studio monitors, digital amplifiers, multichannel processors, and clock-distribution modules built around the CS8411/12 receiver family. Treat the recovered clock as a sensitive digital signal: route it over a continuous reference plane, minimize stub branches, avoid crossing noisy power-converter nodes, and verify startup behavior when the source clock is absent or changes format.

Notas de projeto
Assign all 28 pins from the Cirrus Logic pin-description table before schematic capture, because the package is a PDIP footprint and the complete pin map is not reproduced here. Keep the receiver's ground connections tied directly to the surrounding ground plane, avoid placing switching-regulator loops beneath the IC, and route recovered-clock and serial-data nets away from high-current switching nodes. Use the manufacturer application diagram to preserve the intended grounding and termination topology.
Build the digital-audio input around the manufacturer reference circuit, including the required source impedance and termination arrangement. Check the receiver eye margin with the actual connector, cable length, source voltage, and PCB loading rather than relying only on bench-level point-to-point measurements. A continuous ground reference beneath the interface and short return paths reduces susceptibility to common-mode noise and helps preserve usable timing margin.
Do not treat the 256x Fs output as a free-running oscillator: it is derived from the received digital-audio stream. Plan startup, source-loss, format-change, and power-sequencing behavior in the surrounding system. Before using CS8412-CP as a substitute, compare every pin function, supported mode, output-clock characteristic, supply range, and package dimension with the CS8411-CP rather than assuming that the family name alone guarantees interchangeability.
Follow the datasheet's power-supply and decoupling recommendations for both voltage rails. Place required bypass capacitors at the associated IC pins with short ground returns, and separate sensitive receiver returns from noisy converter and digital-output return currents where the application circuit permits. Confirm supply tolerance, startup current, and power-sequencing requirements against the official electrical-characteristics and application sections before releasing the PCB.
