The BU1424K is an IC that converts digital RGB / YUV input to composite (NTSC / PAL / PAL60), luminance (Y), and chrominance (C) signals, and outputs the results. Features 1) Input clocks supported. 27.0 / 13.5MHz 28.636 / 14.318MHz 28.375 / 14.1875MHz 35.4695 / 17.73475MHz 2) 24-bit RGB and 16-bit YUV input signals are supported. 3) Both master and slave systems are supported. 4) 9-bit high-speed DAC is used for DAC output of composite VIDEO, Y, and C signals. 5) Internal 8-color OSD output function is provided. 6) FSC-TRAP on the Y channel can be turned on and off. 7) C channel is equipped with an internal chrominance band-pass filter in addition to the U,V. low-pass filter. 8) 5V single power supply, low power consumption. (0.4W typ.) 9) Y and C output can be turned off (the power consumption with Y and C off is 0.25W typ.). Applications Video interfaces for VIDEO-CDs and CD-G decoders
