USB 3.0 camera reference design: 13 Mpx & 21 fps

August 13, 2015 // By Graham Prophet
Cypress Semiconductor and THine Electronics (Tokyo) claim the fastest USB 3.0 camera reference design kit with 13-megapixel resolution at 21 frames per second. The Ascella design kit is based on Cypress’s EZ-USB CX3 USB 3.0 camera controller and THine’s THP7312 image signal processor (ISP).

With optimised firmware, a software development kit, reference circuit schematics and related materials, the kit aims to accelerate time-to-market without expensive initial costs for developing camera firmware. The kit delivers high-resolution performance and advanced functions such as auto-focus and live video streaming for a broad range of consumer, industrial, medical, educational and automotive applications. The Ascella USB 3.0 Camera Reference Design Kit is available through e-con Systems , a product design services company specialising in advanced camera solutions.

Cypress’s CX3 adds SuperSpeed USB connectivity to any image sensor that is compliant with the MIPI Camera Serial Interface 2 (CSI-2) standard, and THine’s THP7312 ISP supports high-resolution performance up to 16 megapixels with high levels of throughput and low power consumption. The reference design kit by Cypress and THine enables plug-and-play operation and includes firmware optimised for all USB camera functions, shortening development time and reducing engineering costs. Developers can use this smart reference design kit as a production-ready final product and can also use it as a development tool for high-resolution camera systems.

Cypress adds that the kit, “...provides a compelling demonstration of using 5-Gbps SuperSpeed USB technology in camera and imaging applications.”

“This kit absolutely brings designers of higher-resolution applications an effective solution to drastically shorten development time with optimised firmware and widely-applicable USB interface technology,” Thine comments.

The Cypress and THine Ascella USB 3.0 reference design kit addresses wide-ranging camera applications in consumer electronics, notebook/tablet PCs, as well as industrial, medical, machine-vision and educational usages. It also targets microscopes, copiers, document scanners, gaming consoles, TV conference systems and other imaging systems.

Features of the Ascella USB 3.0 Camera Reference Design Kit include;

• Support for auto-focus, auto-exposure, auto-white-balance and the ability to select from 20 picture resolutions

• Support for streaming of live video at 4K with 30 fps and 1080p with 60 fps

• Support for tuning functions through USB Video Class Control and extensions
