CS4223-BS - 24-Bit 105dB Stereo Audio Codec | Cirrus Logic
Артикул: CS4223-BS ✗ Снят с производстваCS4223-BS Обзор
An audio codec is an interface IC that converts analog sound signals into digital data and reconstructs digital audio into analog signals. A codec belongs to the broader interface IC and signal-conversion hierarchy, combining an ADC, DAC, digital audio interface, clocking, and associated analog support functions. This integration reduces the number of external converters required in CD players, DVD systems, automotive audio equipment, consumer electronics, and other stereo-audio systems.
Key features include 24-bit audio resolution, a specified signal-to-noise ratio of 105 dB, stereo ADC and DAC channels, delta-sigma conversion, and single +5 V operation. The 105 dB rating provides a concrete measure of the converter noise floor relative to the full-scale signal, while 24-bit words provide sufficient numerical resolution for professional and consumer audio paths. The 28-pin SSOP surface-mount package supports compact, board-level implementations.
The device accepts digital audio through its serial audio interface and uses external clocking and synchronization signals for deterministic conversion. Delta-sigma architectures reduce the need for high-precision conversion components inside the signal path, although board layout, grounding, supply decoupling, and clock signal integrity remain important. Analog and digital sections should be routed to minimize coupling from switching nodes and high-current return paths.
Typical applications include stereo CD and DVD audio, home-theater equipment, automotive sound systems, digital mixing consoles, multimedia appliances, and other systems requiring simultaneous analog-to-digital and digital-to-analog conversion. The CS4223-BS is appropriate where a 24-bit stereo codec and 105 dB dynamic range are required from one +5 V supply. Because the verified listing identifies this -BS option as lacking volume control, systems requiring an internal volume-control function should verify that requirement before design-in.
For a new PCB, place all decoupling capacitors close to their supply pins, use a low-inductance ground reference, and route clock and data traces away from analog inputs. The +5 V rail should be filtered if nearby switching converters create ripple or high-frequency noise. Legacy-product risk should also be evaluated because the available cross-reference data labels the CS4223 family as obsolete and recommends consulting manufacturer lifecycle information before committing to a production run.

Stereo CD and DVD Audio Equipment
The CS4223-BS fits legacy CD and DVD audio products because it combines stereo analog-to-digital and stereo digital-to-analog converters in one 24-bit codec. According to the verified Cirrus Logic family description, both converter paths use delta-sigma techniques and the IC operates from a single +5 V supply, reducing the number of separate conversion devices required around a digital-audio subsystem. The 105 dB specified signal-to-noise ratio supports a clean stereo playback and capture architecture. In a new design, however, engineers must preserve the original 28-pin SSOP footprint and confirm serial-audio timing, clocking, and analog pin assignments. The part’s obsolete status means it should be selected primarily for repair, replication, or legacy-platform continuation rather than a new high-volume consumer program.

Automotive Audio Head Units
The CS4223-BS is architecturally suitable for legacy automotive head units requiring a 24-bit stereo codec with both ADC and DAC functions on +5 V. Its 105 dB specified signal-to-noise ratio and delta-sigma conversion provide a defined basis for evaluating microphone capture, radio-audio processing, and playback paths. The verified distributor description confirms the stereo converter configuration, although it does not establish AEC-Q100 qualification for the -BS suffix. Automotive engineers must therefore verify the operating-temperature range, EMC-related circuit guidance, load regulation, and qualification status in the manufacturer documentation. Because the device is presented as obsolete, production sourcing should include traceability and long-term availability review rather than relying on ordinary new-design lifecycle assumptions.
Рекомендуется
Home Theater and Multimedia Systems
The CS4223-BS can serve as the central stereo conversion device in a legacy home-theater or multimedia appliance when the board already uses its 28-pin SSOP interface. The verified family description identifies 24-bit stereo ADC and DAC converters, delta-sigma operation, and a single +5 V supply, which suits equipment that must accept analog line-level audio while also generating digital playback audio. Its 105 dB specified signal-to-noise ratio provides a useful comparison point for output-chain design. A complete implementation must still account for clock generation, serial data routing, analog filtering, and output-amplifier loading. Because the available data marks the device obsolete, engineers should compare it with a current codec before starting a substantially new multimedia platform.

Digital Audio Recording and Capture
The CS4223-BS is appropriate for a legacy stereo capture board that requires simultaneous analog recording and digital-audio monitoring. Its stereo ADC supports conversion from analog line sources, while the integrated stereo DAC supports monitoring or test outputs. The verified Cirrus Logic description confirms 24-bit delta-sigma conversion and 105 dB performance, giving designers concrete resolution and noise criteria when evaluating the analog front end. The -BS option is specifically listed as lacking volume control, so gain must be managed through external analog circuitry, an external digital gain-control device, or the system mixer. Layout work should isolate analog inputs from digital clocking and switching paths, while production planning must account for the obsolete lifecycle status and remaining-market availability.

Industrial Audio Control Panels
The CS4223-BS can support a legacy industrial audio-control panel that accepts analog stereo sources and must present digital audio to a controller. The integrated 24-bit ADC and DAC reduce the component count compared with separate converters, while the specified 105 dB signal-to-noise ratio provides a useful baseline for intercom, monitoring, and machine-audio systems. Its +5 V analog and digital supply architecture is compatible with older control electronics, but the obsolete status requires careful counterfeit and obsolescence risk assessment. For an existing board, use the exact manufacturer pinout and reference layout; for a new panel, evaluate current codecs that may offer more supply options, smaller packages, and stronger availability. External gain control is required if system operators expect an internal volume-control function.

Professional Audio Interface Retrofit
The CS4223-BS is useful when retrofitting a professional stereo-audio interface that already relies on the original Cirrus Logic pin arrangement. It provides 24-bit stereo ADC and DAC conversion, delta-sigma signal processing, 105 dB specified performance, and +5 V operation in a 28-pin SSOP package. These characteristics allow a technician to preserve an existing board while replacing a failed converter rather than redesigning the clock, digital interface, and analog routing sections. The Mouser listing notes that this -BS configuration has no volume control, which may require an external gain-control solution. Because the cross-reference material calls the component obsolete, procurement should emphasize original packaged parts, traceability, electrical testing, and confirmation that the replacement lot matches the original revision.

Заметки по проектированию
Treat the analog and digital sections as separate return domains until the manufacturer reference layout is reviewed. Place supply-decoupling capacitors directly beside the appropriate +5 V and ground pins, keep analog-input traces short, and avoid routing them beneath digital clock, serial-data, or high-current output paths. The verified data does not provide required capacitor values or trace-spacing limits, so those details must be taken from the CS4223/4 family datasheet rather than inferred from generic layout rules.
The verified family description confirms single +5 V operation but does not provide the complete current rating, voltage tolerance, startup behavior, or bypass-capacitor network. Do not assume that a nominal 5 V rail is sufficient without checking minimum and maximum operating voltage and supply-current conditions in the manufacturer document. If the codec shares a rail with switching converters, include appropriate filtering and verify that conducted and radiated noise do not degrade the converter’s specified 105 dB performance.
Preserve the original CS4223-BS footprint and pin assignments when repairing an existing PCB. The verified results identify a 28-pin SSOP package but do not provide a complete pin table, so engineers should not rely on an unreferenced third-party drawing for production artwork. Cross-check pin 1 orientation, exposed pad usage if any, analog inputs and outputs, digital audio lines, clocks, reset, and ground connections against the exact manufacturer datasheet. Validate the assembled board’s clock timing and audio channels before production release.
Do not substitute a codec merely because it also resolves 24-bit stereo audio. The verified cross-reference results do not establish a pin-compatible alternative, and the target’s -BS suffix is specifically listed without volume control. A valid replacement must match the 28-pin SSOP footprint, supply requirements, digital-audio protocol, master/slave clocking, analog pin functions, and control interface. Also avoid assuming that distributor inventory is production-sustainable because the family is identified as obsolete.
Информация о соответствии
The verified sources do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements for CS4223-BS. Its suitability for an automotive application must therefore be confirmed from the exact manufacturer documentation.
