Big Fish Semiconductor’s U2 5.2 Audio SoC enters mass production with Dolphin Design’s Audio IPs

Our brand new U2 5.2 Audio SoC is a game-changer in the TWS Bluetooth headset market with its ultra-low power consumption. But none of this would have been possible without Dolphin Design's Audio IP. It has a high-fidelity ADC that combines superior audio performance with a small footprint and ultra-low power consumption, which is exactly what we, at Big Fish Semiconductor, were looking for. We are delighted with this partnership with Dolphin Design, which will continue for our future SoC developments.

C-SKY Microsystems selects Dolphin Design's energy management offering for smart voice-interactive devices

The emergence of powerful voice recognition algorithms drives the growth of connected devices controlled by voice, where voice recognition and ultra-low power technologies are key to delivering the optimal user experience. The complete set of Foundation, Feature and Fabric IPs of Dolphin Design will allow us to demonstrate fast and safely a human-machine interaction system relying on a C-Sky microcontroller-based SoC platform.

Shanghai Zhaoxin Semiconductor Co., Ltd. licenses Dolphin Design ultra dense audio DAC for its next generation of Set Top Box

Our experience of using Dolphin Design’s ultra-dense audio DAC has been very positive. A pure logic DAC is extremely compact at 28nm and enables to drastically reduce the industrial test duration, as structural testing such as SCAN can efficiently be applied, which is pivotal for our SoC competitiveness on the aggressive market of Set-Top Boxes.

Mnano selects Dolphin Design's six-channel Audio converter for its next generation of Smart Speakers

Meeting the right balance between silicon costs, audio quality and low power consumption is a challenging task. The YANZI-A-hexADC-VD.01, a feature-rich audio ADC from Dolphin Design, packs all these advantages into our smart speaker offering.

Remove distractions. Augment your sound experience.

Ultra low latency audio converters down to 3µs

Active Noise Cancellation allows you to listen to audio content without raising the volume excessively. We provide a powerful set of converters to make high-fidelity ANC possible.

ADC with Dynamic Range higher than 106 dB maintaining audio performance in analog mic-in mode
Pop-up noise level as low as – 60 dBV

Ultra efficient and accurate voice command detection. Wake up when effectively required.

Audio CODEC with embedded Voice Activity Detection

The built-in microphones in smart speakers are continuously listening for “hot keywords” followed by a command. To maximize the sleep state mode timeshare to limit the system power consumption, we designed audio CODEC solutions with voice activity detection capability, the Whisper Trigger^TM.

Enables ultra low power keyword spotting mode
High Dynamic Range – up to 106 dB – to perform far-field voice recognition

Accurate sound processing. Reliable voice interaction.

Audio CODEC with high Noise Resilience

Engage seamless in-vehicle voice command and response interactions with robust noise tolerance in a high-temperature environment.

High CMRR enabling in-vehicle distributed mic positioning
Low crosstalk multi-channel CODEC
Embedded low noise voltage regulator for enhanced resilience to power supply-related noise

More than ever before, attention to power consumption is paramount when developing new products. In this environment, voice activity detection has a major role to play in any new voice-controlled system. The main objective of VAD is to lower power consumption, saving on computation or data processing by deactivating part of the SoC when no speech patterns are detected.
Markets like home assistants and telecommunications can greatly benefit from this feature as the
always-on mode is not exactly suitable for wireless products or when privacy is a concern.
