GL864A
產品簡述

The GL864A is a high performance USB 2.0 UVC compliant controller mainly for PC Camera and NB camera applications. GL864A provides up to 30 fps at HD 720p (1280x720) resolution. GL864A also supports USB isochronous mode to provide certain bandwidth to insure user can get smooth usage experience on video applications even running high bandwidth consumption devices concurrently.

 

The GL864A is compliant with USB Video Class 1.1. It works with Microsoft native inbox Windows driver which is bundled with all WinXP SP3, Vista, Windows 7 and Windows 8. Alternatively, Genesys Logic provides proprietary drivers for GL864A to enable users for better image performance and special function requirement.

 

The GL864A has a built-in MJPEG engine and hardware ISP to process RAW data from CMOS sensor to provide high resolution and high frame rate of video stream. It supports up to 30fps at 720p (1280x720) resolution. 

 

GL864A provides industry leading cost-effective OCCS (on chip clock source), which eliminates the need of an on board crystal for USB frequency. It also has a built-in 2-channel voltage regulator.
