MAX11508

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 commercial (0°C to +85°C)temperature range. The parts are offered in the 14-pin TSSOP package. Selectable input bias circuitry on 2 filter channels offers simple connection to bipolar video signals such as C, Pb, and Pr. It filters provide -3dB bandwidths of 9MHz (SD), 16MHz (PS), 33MHz (HD), and 60MHz (BP). 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 ACand 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. The MAX11509 filters provide -3dB bandwidths of 10MHz (SD), 17MHz (PS), 34MHz (HD), and 60MHz (BP). Each channel includes an output buffer with +6dB gain that provides a full 2VP-P video signal into a 150video load. The buffers drive either ACor DC-coupled loads and assure a blanking level of below 1V after the backmatch resistor. The shutdown mode provided reduces device current to 1A (typ).

The features of MAX11508 can be summarized as (1)three selectable 6th-order 9MHz/16MHz/33MHz (SD/PS/HD)filters; (2)bypass mode for high bandwidth signals; (3)transparent input clamp; (4)output buffers drive a standard 150 video load; (5)±12kV HBM ESD protection on outputs; (6)AC- or DC-coupled inputs; (7)AC- or DC-coupled outputs; (8)+0.8dB peaking passband response (MAX11509)in SD, PS, and HD Modes; (9)single +5V power supply; (10)lead-free, 14-Pin TSSOP package.

The absolute maximum ratings of MAX11508 are (1)VCC to GND: -0.3V to +6V; (2)all other pins to GND: -0.3V to the lower of (VCC + 0.3V)and +6V; (3)continuous power dissipation (TA = +70°C)14-Pin TSSOP (derate 10mW/°C above +70°C): 796.8mW; (4)maximum current into any pin except VCC and GND: ±50mA; (5)operating temperature range: 0°C to +85°C; (6)storage temperature range: -65°C to +150°C; (7)lead temperature (soldering, 10s): +300°C; (8)junction temperature: +150°C.
