6-ch video filter enables HD media players

The ADA4424-6 video filter features three SD and three ED/HD channels and a flat frequency response, providing 0.1-dB passband flatness with no peaking, which is required by 1080p high-definition-compliant media players and recorders. The part’s SD channels operate flat to 6.75 MHz and include two fifth-order Butterworth filters for SD filtering, while the ED/HD channels are composed of three fifth-order Butterworth filters and operate within 0.1 dB peaking typically, out to 13.5 and 30 MHz.

The filter features an integrated charge pump that allows the outputs to swing up to 1.4 V below ground. The output drivers on the ADA4424-6 feature rail-to-rail outputs with a fixed gain of 6.2 dB. Each output can drive two double-terminated 75-Ω cables simultaneously. The filter/buffer section operates from a single 3.3-V supply. The device includes a dedicated 5-V supply pin used for D connector and S1 /S2 signaling support. ($1.49 ea/1,000 — samples available now.)
