MAX11508/MAX11509
The MAX11508/MAX11509 integrated 3-channel video filters for high-definition (HD), progressive-scan (PS), standard-definition (SD), and bypass (BP) video include an output buffer with +6d B gain and are ideal for digital video disc (DVD) players, set-top box (STB) receivers, high-definition television (HDTV), digital video recorders (DVRs), and similar devices. The MAX11508/MAX11509 video inputs feature a transparent clamp patible with AC- and DC-coupled .. input signals and allow DAC outputs to be directly coupled, eliminating the need for bulky coupling capacitors. The filter bandwidths are selectable to HD, PS, and SD. A BP mode is provided for 1080p and highbandwidth RGB signals. Selectable input bias circuitry on 2 filter channels offers simple connection to bipolar video signals such as C, Pb, and Pr. The MAX11508 filters provide -3d B bandwidths of 9MHz (SD), 16MHz (PS), 33MHz (HD), and 60MHz (BP). The MAX11509 filters provide -3d B bandwidths of 10MHz (SD), 17MHz (PS), 34MHz (HD), and 60MHz (BP). Each channel includes an output buffer with +6d B gain that provides a full 2VP-P video signal into a 150Ω video load. The buffers drive either AC- or DC-coupled loads and assure a blanking level of below 1V after the backmatch resistor. The shutdown mode provided reduces device current to 1µA (typ). The MAX11508 offers a flat passband and the MAX11509 features
+0.8d B peaking to pensate for DAC rolloff. The MAX11508/MAX11509 operate from a 5V power supply and operate over the upper mercial (0°C to +85°C) temperature range. The...
