In April 2021, after nearly half a year of preparation and 45 days of actual measurement and optimization, the audio codec chip product CX11880/11970 of Senarytech successfully passed Intel's Evo product test.
Intel Evo is a series of product standards developed by Intel using its industry influence. In August 2019, Intel released a certification system called "Athena Project" when releasing the 10nm processor. The Intel Evo platform can be regarded as the second stage of the "Athena Project" certification standard. Jiong Zheng from Intel said at the 2021 Spring Intel Evo Platform Media Sharing Conference that the Intel Evo platform has extremely strict target specifications, which provides specific tests of multiple scenarios like "consistent performance", "quick wake-up" and "long battery life" as well as "fast charging" for partners' notebook products, and conducts specific requirements for the specific hardware configuration of the product.
CX 11880/11970 is one of the flagship products of Senarytech, which is mainly used in sound cards of various PC products such as desktops, notebooks, and tablets. Qingshun Yang, head of sales of Senarytech, said how Senarytech can bring customers a better experience on the Intel Evo platform, how to polish excellent hardware products with Intel to meet Intel's stringent certification requirements, and finally, how to provide customers with the best Evo platform experience, these experiences he mentioned are impressive.
"For the CX11880/11970, these two products are our audio codec chips. The most important parameters are the digital-to-analog conversion signal-to-noise ratio and the analog-to-digital conversion signal-to-noise ratio”, said Yang, “The efficiency of our products will be 6 % higher than other products. The effect of analog to digital exceeds 11%, which is also an important indicator. Of course, the speaker driver is quite important in notebooks. Our driving speaker capability is far higher than other chips provided by customers in the market, which can reach 2.8W, while other chips are only 2.2W. The power consumption of the Senarytech’s chip is 1 milliwatt at the headphone output. The lower the chip power consumption, the better the performance of the chip." Mr. Yang also expresses special thanks to Intel OpenLab for its highly detailed test plan, including an excellent scientific guidance method.
