BU6521KV Datasheet | ROHM

Description BU6520KV, BU6521KV are video encoders with built-in AIE image correcting function. Also, BU6521KV has the image correcting function of the fog reduction, too. Fog Reduction, the brightness correction, the backlight correction and the chroma emphasis can improve the visibility of the input image of the camera. - AIE and Fog Reduction function are image processing technology by ROHM’s hardware. - Features 1) Format of video output is patible with NTSC/PAL posite video format (CVBS). Built-in DAC with direct 75Ω drive capability. - 1 2) Built-in Fog Reduction function , dynamic range correction, edge-emphasizing filter and gamma filter. 3) Input/output data format is patible with ITU-R BT.656 and YCb Cr=4:2:2 with synchronization signal. 4) patible with NTSC (27MHz, 28.63636MHz and 19.06993MHz)/ - 2 PAL(27MHz, 28.375MHz, 35.46895MHz and 18.9375MHz) . 5) Registers can be set up with a 2-line serial interface. 6) Registers can be automatically set up by reading from external EEPROM, when after resetting or changing mode. - 1 As for the Fog Reduction feature , it loads only BU6521KV. - 2 NTSC 19,06993 MHz and PAL 18,9375 MHz support only BU6521KV. - Applications Security camera, camera for automotive, drive recorder etc. - Line up matrix Power Sopply Image size Voltage(V) Input Interface Control Interface Output Interface Temperature Operating Range(℃) Part No. Feature Package 2 1.4 to 1.6 I C, 8bit, 8bit, 720x480, Serial (VDDCore) BU6520KV YUV=4:2:2, YUV=4:2:2, 2.7 to 3.6 SD size EEPROM ITU-R BT.656 ITU-R BT.656 (VDDI/O, AVDD) interface AIE, Video output -40 ~ +85 VQFP48C 2 1.4 to 1.6 I C, AIE, 8bit, 8bit, 720x480, Serial (VDDCore) Fog reduction, BU6521KV YUV=4:2:2, YUV=4:2:2, SD size 2.7 to 3.6 EEPROM Video output ITU-R BT.656 ITU-R BT.656 (VDDI/O, AVDD) interface -40 ~ +85 VQFP48C I2C BUS is a registered trademark of Philips .rohm. © 2010 ROHM Co., Ltd.
