Fairchild FIN210照相机模块的10位串-并转换方案

Fairchild 公司的FIN210是低功耗10位并串/并串转换器,支持照相机和小型显示器,时钟速率高达48MHz.接口包括MCU,RGB和YUV,待机电流小于10uA,内核工作电压2.8V-3.6V,I/O电压1.65V-3.6V,I/O到低的ESD保护高达15KV,主要应用于移动手机,打印机和安全照相机.本文介绍了FIN210的主要特性,以及各种应用案例,包括在手机, 8位RGB, 8位YUV 130万象素CMOS传感器以及8位仅写入MCU接口的应用框图.

FIN210AC: 10-Bit Serializer / Deserializer Supporting Cameras and Small Displays up to 48MHz

The FIN210AC μSerDes™ is a low-power serializer / deserializer optimized for use in cell phone displays and camera paths. The device reduces a 10-bit data path to four wires. For camera applications, an additional master clock can be passed in the opposite direction of data flow. The device utilizes Fairchild’s proprietary ultra-low power, low- EMI technology.
