MAX11508/MAX11509 19-4346 Rev 0 10/08 Low-Cost, 3-Channel, HD/PS/SD/BP Video Filters with Buffer General Description Features The MAX11508/MAX11509 integrated 3-channel video Three Selectable 6th-Order 9MHz/16MHz/33MHz filters for high-definition (HD), progressive-scan (PS), (SD/PS/HD) Filters standard-definition (SD), and bypass (BP) video Bypass Mode for High Bandwidth Signals include an output buffer with +6dB gain and are ideal for digital video disc (DVD) players, set-top box (STB) Transparent Input Clamp receivers, high-definition television (HDTV), digital Output Buffers Drive a Standard 150 Video Load video recorders (DVRs), and similar devices. The MAX11508/MAX11509 video inputs feature a trans- 12kV HBM ESD Protection on Outputs parent clamp compatible with AC- and DC-coupled AC- or DC-Coupled Inputs input signals and allow DAC outputs to be directly cou- pled, eliminating the need for bulky coupling capaci- AC- or DC-Coupled Outputs tors. The filter bandwidths are selectable to HD, PS, +0.8dB Peaking Passband Response (MAX11509) and SD. A BP mode is provided for 1080p and high- in SD, PS, and HD Modes bandwidth RGB signals. Selectable input bias circuitry on 2 filter channels offers simple connection to bipolar Single +5V Power Supply video signals such as C, Pb, and Pr. Lead-Free, 14-Pin TSSOP Package The MAX11508 filters provide -3dB bandwidths of 9MHz (SD), 16MHz (PS), 33MHz (HD), and 60MHz (BP). The MAX11509 filters provide -3dB bandwidths of 10MHz (SD), 17MHz (PS), 34MHz (HD), and 60MHz (BP).

The MAX11508 offers a flat passband and the MAX11509 features +0.8dB peaking to compensate for DAC rolloff. The MAX11508/MAX11509 operate from a 5V power supply and operate over the upper commer- cial (0C to +85C) temperature range. The parts are Pin Configuration offered in the 14-pin TSSOP package.
