MAX11504

Four-Channel, Standard-Definition Video Filters

SD Video Filter Buffer with Improved Stop-Band Attenuation and 12kV ESD Protection


Please check latest availability status for a specific part variant.

Description

The MAX11504/MAX11505 integrated filters offer four channels of 5th order filters for standard-definition video and include +6dB output buffers on each channel. These video filters are ideal for anti-aliasing and DAC smoothing in applications such as set-top boxes, security systems, digital video recorders (DVRs), DVD players, and personal video recorders.

The MAX11504/MAX11505 video inputs feature a transparent clamp compatible with AC- and DC-coupled input signals and allow DAC outputs to be directly coupled. The 5th order filters provide a bandwidth of 8.6MHz (typical). The MAX11504 offers a flat passband response on all channels. The MAX11505 offers a 0.8dB peaking passband response on Channel 1, resulting in a bandwidth of 8.9MHz (typical) and a flat passband response on all other channels.

Each channel includes an output buffer with a gain of +6dB capable of driving a full 2VP-P video signal into two standard 150Ω (75Ω back terminated) video loads. The buffers drive either AC- or DC-coupled loads and assure a blanking level below 1V after the back-match resistor.

The MAX11504/MAX11505 operate from a single +5V supply and are available in the 0°C to +70°C commercial temperature range. These devices are available in small 10-pin µMAX® packages.
