BU1521GVW-E2 ROHM

Video Accessory IC Series For portable image equipment Upscaler IC No.09069EAT02 BU1521GVW Description BU1521GVW upscales and interpolates images when upconverting to the HDTV (Maximum 1080P) format from the usual SDTV (NTSC/PAL) format. High quality IP changeup scale management is realized by the frame memory less operate. It is the LSI which is the most suitable for the compact system of the mobile.
