AIE Adaptive Image Enhancer Series Video Encoders built-in Image Correction No.10060ECT03 BU6520KV,BU6521KV 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 ROHMs hardware. Features 1) Format of video output is compatible with NTSC/PAL composite video format (CVBS). Built-in DAC with direct 75 drive capability. *1 2) Built-in Fog Reduction function , dynamic range correction, edge-emphasizing filter and gamma filter. 3) Input/output data format is compatible with ITU-R BT.656 and YCbCr=4:2:2 with synchronization signal. 4) Compatible 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 Temperature Power Sopply Input Control Output Part No. Image size Feature Operating Package Voltage(V) Interface Interface Interface Range() 2 1.4 to 1.6 I C, 8bit, 8bit, (V Core) 720x480, Serial AIE, DD BU6520KV YUV=4:2:2, YUV=4:2:2, -40 ~ +85 VQFP48C 2.7 to 3.6 SD size EEPROM Video output ITU-R BT.656 ITU-R BT.656 (V I/O, AV ) interface DD DD 2 1.4 to 1.6 I C, AIE, 8bit, 8bit, (V Core) 720x480, Serial Fog reduction, DD BU6521KV YUV=4:2:2, YUV=4:2:2, -40 ~ +85 VQFP48C 2.7 to 3.6 SD size EEPROM Video output ITU-R BT.656 ITU-R BT.656 (V I/O, AV ) interface DD DD 2 I C BUS is a registered trademark of Philips www.rohm.com 2010.02 - Rev.C 1/18 2010 ROHM Co., Ltd.
