philips系列SAA5284单片机解密开发

深圳芯片解密研究所解密事业部专业承接SAA5284单片机解密服务,我们专业的解密技术团队整合既有的解密技术资源,将为广大客户提供安全可靠、具备极强的经济价值的IC解密方案。
这里我们提供对单片机SAA5284的基本性能特征介绍,供客户及工程师参考借鉴。
The SAA5284 is a Vertical Blanking Interval (VBI) and Full Field (FF) video data acquisition device tailored for application on PC add-in cards, PC mother-boards, set-top boxes and as a SAA5250 replacement. The IC in combination with a range of software modules will acquire most existing formats of broadcast VBI and FF data.These associated software modules are available under licence. Scope is provided for acquiring some as yet unspecified formats. The SAA5284 incorporates all the data slicing, parallel interface, data filtering and control logic. It is controlled either by a parallel interface or I2C-bus. It can output ASCII VBI data as pixels on the digital video bus where no parallel port is available. It is available in a QFP44 package.
