MAX11509

19-4346; Rev 0; 10/08 KIT ATION EVALU E L B A IL AVA Low-Cost, 3-Channel, HD/PS/SD/BP Video Filters with Buffer General Description Features ♦ Three Selectable 6th-Order 9MHz/16MHz/33MHz (SD/PS/HD) Filters ♦ Bypass Mode for High Bandwidth Signals ♦ Transparent Input Clamp ♦ Output Buffers Drive a Standard 150Ω Video Load ♦ ±12kV HBM ESD Protection on Outputs ♦ AC- or DC-Coupled Inputs ♦ AC- or DC-Coupled Outputs ♦ +0.8dB Peaking Passband Response (MAX11509) in SD, PS, and HD Modes ♦ Single +5V Power Supply ♦ Lead-Free, 14-Pin TSSOP Package 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 +6dB 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 compatible with AC- and DC-coupled www.DataSheet4U.com 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 -3dB bandwidths of 9MHz (SD), 16MHz (PS), 33MHz (HD), and 60MHz (...
