SunplusIT's, a technology leader in PC webcams, had successfully deployed USB 2.0 webcams in multiple brand-name products. Due to this success, the company was approached to develop a USB 3.0 webcam, the SPCA2100A, which takes advantage of the 5 Gbps speeds that the USB 3.0 specification defines. To accelerate and simplify product development, SunplusIT required third-party PHY and controller IP that was certified by the USB-IF, PHY IP that was available on their required process node, and controllers that were compatible with USB video class drivers. It was critical for SunplusIT to maintain their industry leadership and focus on their core competencies instead of focusing on developing and integrating the USB 3.0 IP.
To support these goals, SunplusIT required a reliable solution that would minimize integration effort and function as required in their complex webcam SoC. Only DesignWare USB 3.0 PHY and controller IP met their need for high-quality, certified USB IP.
High-Quality DesignWare IP
SunplusIT needed to maintain its technology leadership and differentiate itself by offering USB 3.0 speeds in its PC webcam. They required an IP vendor that they could trust to deliver easy-to-integrate products that would work together seamlessly.
"Minimizing risk to ensure first-pass silicon success was necessary when choosing our third-party IP vendor,” said G.T. Hsiao, R&D Manager, SunplusIT. “Our prior high-volume production experiences with Synopsys USB IP demonstrated that the IP is very robust and offers excellent quality, which lead us to select it again for our latest project. Using Synopsys for both the USB PHY and controller in our SPCA2100A webcam was a key way that we reduced risk."
SunplusIT faced SoC design challenges to achieve faster processing for a complicated SoC architecture in a small footprint. Using a comprehensive USB IP solution in a proven subsystem, including both PHY and controller IP, was paramount.
"Integrating both USB PHY and controller IP that were proven to work together was critical to our project's success," said Hsiao. "Our decision to use both DesignWare USB 3.0 PHY and Controller IP helped simplify the SoC design and integration. We look forward to using DesignWare IP our next projects, as well."
Maintaining technology leadership with our new generation of PC webcams required reliable, high-quality USB 3.0 IP. After our excellent experiences using DesignWare USB 2.0 IP, we knew that we would go back to Synopsys for USB 3.0 IP, and our first-silicon success demonstrates that we made the right choice.
