Product Summary

The MAX7428EKA-T is a standard definition video reconstruction filter and buffer, which is low-cost, high-performance replacements for standard discrete filter and buffer solutions.The MAX7428EKA-T is 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 MAX7428EKA-T features Maxim’s single-pin bus 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 MAX7428EKA-T is widely used in set-top boxes, DVD players, hard-disk recorders and camcorders.
