The MAX7428 filters is low-cost, high-performance replacements for standard discrete fil-ter and buffer solutions. The MAX7428 is ideal for anti-aliasing and DAC smooth-ing video applications, when analog video is reconstruct-ed 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 features 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.
