MAX7428/MAX7430/MAX7432 Standard Definition Video Reconstruction Filters and Buffers The MAX7428/MAX7430/MAX7432 filters are low-cost, high-performance replacements for standard discrete filter and buffer solutions. The MAX7428/MAX7430/ MAX7432 are ideal for anti-aliasing and DAC smoothing video applications, when analog video is reconstructed from a digital data stream. These devices require a single +5V supply and the filters have a cutoff frequency optimized for NTSC, PAL, and standard definition digital TV SDTV video signals. The MAX7428/MAX7430/ MAX7432 feature Maxim’s Single Pin Bus MSPB interface to digitally control channel selection IN_A or IN_B , adjust high-frequency boost, bypass the filter, configure luma vs. chroma operation, and control the output disable. The MAX7428 single-channel filter is ideal for composite CVBS video signals. The MAX7430 dual filter is optimized for S-Video Y/C applications. The MAX7432 triple filter is optimized for component YPbPr or embedded synchronous RGB video signals. The MAX7428 is available in a tiny 8-pin SOT23 package, the MAX7430 is available in a miniature 10-pin package, and the MAX7432 is available in a 14-pin TSSOP package. The MAX7428/MAX7430/MAX7432 are fully specified over the -40°C to +85°C extended temperature range.
