Foreword

Great audio always starts with precision. In this audio-focused edition of our newsletter, we highlight the technologies behind clear, stable and high‑quality sound, high‑end timing devices and FPGA‑based solutions.

Accurate clocking and ultra‑low jitter is key to reliable audio performance, while FPGA platforms enable flexible, low‑latency signal processing for demanding designs. 

Below, we share a selection of solutions that help designers build professional and future‑proof audio systems, with consistent sound quality.

No matter the application, we are ready to support your next audio project.

Looking for the right Audio ADC for your next audio design?

The Cirrus Logic CS530x series offers high-performance audio ADCs for professional and consumer audio applications.

The product family includes the CS5302P 2-channel, CS5304P/S 4-channel and CS5308P/S 8-channel ADC, giving designers flexibility for different system requirements.

These ADCs support 32-bit resolution, differential analog inputs and sample rates up to 768 kHz. They are designed for applications such as digital mixers, USB audio interfaces, home audio, AV receivers, musical instruments, video recording and automotive audio systems.

With strong dynamic range, low distortion and a power budget of around 25 mW per channel, the CS530x family helps developers create transparent, high-quality audio conversion in compact designs.

There is also a complementary DAC series that features the same high end performance: CS4302P, CS4304P and CS4308P.

Looking for the right clocking device for your audio design? 

The Cirrus Logic CS2600, CS2500 and CS2501 are timing devices designed for automotive, professional and digital audio systems. These clocking ICs generate stable, low-jitter clocks from a timing reference, helping audio converters and digital audio systems stay synchronized.

The devices are suitable for applications such as automotive audio systems, network audio, USB audio interfaces, embedded audio systems and professional audio equipment. The CS2500 and CS2501 offer an upgrade path for earlier Cirrus Logic clocking devices, while the CS2600 adds audio-specific outputs such as BCLK and FSYNC for digital-audio applications.

With support for low-jitter clock generation and synchronization, these devices help improve timing stability in high-performance audio designs.

USB2.0-To-I2S - IP for GOWIN FPGAs

GOWIN Semiconductor offers a USB2.0 UAC (USB Audio Class) solution Ref-Design/IP solution for GW1N-Series C7I6 and GW2A-Series C7I6 FPGA devices. 

This solution enables USB2.0-to-I2S audio streaming and is designed for use with Windows PCs, Mac PCs and mobile platforms such as Android, Linux and Apple OS. These platforms can use the vendor’s default audio streaming driver, helping to simplify implementation.

The solution supports multiple audio data widths, sample rates and formats, including 16-bit, 24-bit and 32-bit data width, sample rates up to 768 kHz, and formats such as PCM, IIS, DoP and DSD. A dedicated development board is also available for evaluation and design support.

With this Ref-Design/IP, developers can accelerate the development of USB audio products and reduce design complexity when integrating high-quality audio functionality into FPGA-based systems.

Multi-Channel Spatial Audio solution, IP for GOWIN FPGAs 

3D Spatial Audio is a fast-growing segment in consumer electronics. GOWIN Semiconductor has developed an innovative approach to creating immersive 3D sound, with IP designed for integration into a GOWIN FPGA.

This solution generates sound waves that the listener’s brain perceives at one ear at a time, without the need for a headset. As a result, it can create an immersive home theater surround sound experience from a single loudspeaker array.

By simplifying traditional home theater systems, this technology helps make high-quality spatial audio more accessible and opens new opportunities for consumer audio applications.

SD18OB371-178, Digital MEMS microphone with 69 dB SNR 

The Goermicro SD18OB371-178 is a digital MEMS microphone designed for reliable integration in compact electronic devices.

The SD18OB371-178 replaces the SD18OB371-167 and offers pin-to-pin compatibility, enabling a straightforward migration with minimal PCB or firmware changes.

With a typical SNR of 69 dB, a sensitivity of -37 ±1 dB and an AOP of 128 dBSPL, this microphone offers strong performance for voice and audio capture applications.

Its compact 3.5 x 2.65 x 1.0 mm package makes it well suited for mobile phones, laptops, communication devices and other portable electronics.

Displays visual interface for pro audio control

In professional audio equipment, intuitive control is just as important as signal quality. The Raystar RFB4700 series offers a 7-inch bar-type IPS TFT display with high-resolution visualization in a slim, long-format design.

This makes the display well suited for digital mixers, rack-mounted equipment, broadcast panels and metering interfaces, where space is limited but clear parameter feedback is essential. 

With MIPI DSI support and optional capacitive touch, the RFB4700 series helps engineers create responsive and compact user interfaces for modern pro audio systems.
