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
