General Description

The MAX7428/MAX7430/MAX7432A filters are low-cost, high-performance replacements for standard discrete filter and buffer solutions. The MAX7428/MAX7430/MAX7432A 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/MAX7432A 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.
