Plantronics has always been a leader in the field of audio communications. It is reported that Plantronic's success relies on Dialog Semiconductor's audio and connectivity chipset products. Working with Dialog enables Plantronics to test different frequency options for different regions and countries. , providing the best solution.
For more than a decade, Plantronics, the leader in audio communications for the corporate, government and consumer markets, has relied on Dialog Semiconductor to provide audio and connectivity chipsets, and Dialog products have become the cornerstone of Plantronics' industry-leading wireless audio products.
The Dialog product is now the basis for most of Plantronics' DECT (Digital Enhanced Cordless Communications) product line, which is widely used in most countries of the world.
Similar to the origins of other contemporary technology giants, in 1961, two civil aviation pilots, Courtney Graham and Keith Larkin, put their dreams into practice and created Plantronics in a small garage in Santa Cruz, California. The two founders initially wanted to innovate in commercial aviation headsets and eventually developed the world's first lightweight headset.
This was one of the important milestones of Plantronics in the early days, and it was later in history. NASA's Mercury mission chose Plantronics' MS50 product. Neil Armstrong, the first to step on the moon, also said the first sentence on the moon through the headphones of Plantronics.
More than a decade ago, Plantronics began working with Dialog at a time when the next generation of integrated system-on-chip (SoC) was coming into use. Many competing companies have disappeared from the market, but Dialog provides a new chip design that not only supports many of Plantronics' existing technologies, but also provides other features to help explore wireless headphones with sound quality comparable to wired headphones.
Dialog provides audio codecs for PlantronicsOne product is the SC14450 audio processor, which has been used in many Plantronics hands-free phones and regular phone products for many years.
The SC14480 is another single-chip DECT/CAT-iq solution that can be seen in almost all Plantronics audio products. Ideal for headset applications, the SC14480 has the processing power to support superior sound quality while reducing bill of materials.
The SC14450 processor features a multi-core architecture that provides 240 MIPS of processing power. Equipped with a 16-bit CompactRISCTM processor and two user-programmable Gen2D-SPs, the processor runs multiple audio codecs and combines with other embedded applications to deliver the industry's best echo cancellation.
In addition, the SC14450 supports a variety of external memories with integrated Class D amplifiers, power and battery management options, white LED drivers, and a variety of peripheral interfaces including master/slave PCM, UART, SPI, dual access bus and USB Client.
For wireless audio applications, the DECT standard improves energy efficiency, ease of pairing, support for wideband audio data rates, and secure connectivity. Dialog is the leader in the DECT market, with a product line covering all regional DECT versions and the 2.4GHz DCT protocol, as well as the SmartPulse product line that supports the DECT ULE (Ultra Low Power) standard.
When it comes to DECT, the reason we say "most countries" is because the situation in North America is different. Due to regulatory requirements for US radio frequencies, the United States uses its own standard DECT 6.0. Although DECT 6.0 is almost identical to DECT used in other regions, the use of US standard technology is not compatible with DECT systems elsewhere.
The most fundamental value of Plantronics' collaboration with Dialog is that during the product development phase, teams on both sides can work together to develop chips that meet specific technology needs to support the needs of existing solutions. In some cases, the two companies have worked together to develop chips that are ultimately replicated or used throughout the industry.
For example, a few years ago Dialog developed a chip that required a metal shielded box, a chip developed specifically to meet the needs of Plantronics and slightly modified existing chips, but eventually the chip became the industry standard design and benefited. A bigger headset market.
Whether based on ROM or flash-based, Dialog can provide solutions
The Dialog solution used by many Plantronics headsets is typically based on read-only memory (ROM) or flash-based, depending on the design.
With ROM chips, Plantronics is able to produce low-cost products that can be controlled for long-term performance by writing code to the chip. The Plantronics CS family of products, especially the popular CS500, uses ROM-based chips for cost advantages.
Flash-based chips can be easily upgraded, helping Plantronics products impress customers by regularly upgrading firmware to meet future needs. The Savi 400 and Savi 700 series use flash-based chips.
Because both of these chip solutions are available from Dialog, Plantronics offers solutions for specific applications and industries. It also helps Plantronics make its products better than those connected to PCs through remote upgrades.
For example, due to changes in DECT security standards, Plantronics recently released DECT enhanced security performance upgrades for its flash-based headsets. If customers have a flash-based Plantronics Savi 700 product, they can easily upgrade their firmware to increase security. This option is especially useful for many government customers because security is the most important thing for them in voice communications. This DECT security upgrade is the most upgraded download of Plantronics products. Many customers immediately upgraded their products, and the process is simple and convenient. Plantronics sets industry standards and then goes beyond them.
Plantronics' business model challenges many traditional business models, and its products not only set industry standards, but also exceed quality expectations. Plantronics' products are almost no problem, and in case of problems, Plantronics is also very happy to replace the product. By working with the best suppliers like Dialog, you can design products from the inside out. All Plantronics DECT products with Dialog chips are designed to be extremely reliable, high quality, high performance, and designed for long-lasting use without replacement.
Dialog provides a reference design and software development kit to help Plantronics keep the supply chain running with superior technical support. Dialog also provides evaluation boards and control software to quickly evaluate components, making it easier for Plantronics to accelerate the development process.
The reference design schematic complements Plantronics' custom design to help troubleshoot quickly. As a result, Plantronics is fully capable of accelerating or slowing down production at any point in time, and Dialog helps its operations team better manage any supply chain issues without any significant impact on the production plan.
Another advantage of working with Dialog is that, as a global company, Dialog enables Plantronics to test different frequency options for different regions and countries. Regardless of the market in which the customer is located, Plantronics can quickly prepare a solution.
in conclusionThrough cooperation, Dialog and Plantronics continue to set new industry standards and improve the sound quality of all Plantronics products. Plantronics headsets are widely welcomed in a variety of industries and markets. As part of the joint efforts, the new sound quality standards have made the two companies a market pioneer, and Dialog and Plantronics will continue to play this role in the future.
