The MAX7453 is a low-cost, triple-channel video reconstruction filter for S-video and CVBS video-signal applications. This device is ideal for anti-aliasing and DAC smoothing video applications such as set-top boxes, DVD players, hard-disk recorders (HDRs), and personal video recorders.

The MAX11501/MAX11502 integrated filters offer three channels of 5th-order filters for standard-definition video and include +6dB output buffers on each chan- nel. 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 MAX11501/MAX11502 video inputs feature a trans- parent clamp compatible with AC- and DC-coupled input signals and allow DAC outputs to be directly cou- pled. The 5th-order filters provide a typical -3dB band- width of 8.6MHz (MAX11501) and 8.9MHz (MAX11502) and offer either a flat passband response (MAX11501) or a +0.8dB peaking passband response (MAX11502) on all 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 of below 1V after the back- match resistor. The MAX11501/MAX11502 operate from a single +5V supply and are available in the upper commercial 0°C to +85°C temperature range. These devices are avail- able in small 8-pin SO packages.

The MAX11500 is a three-channel, high-definition (HD) video filter integrated circuit that includes input video clamps and output buffers. This device is ideal for anti-aliasing and DAC smoothing video applications such as set-top boxes, hard-disk recorders (HDRs), DVD players, and personal video recorders. The 6th-order channel filters have a typical -3dB bandwidth of 33MHz. Each channel has an output buffer with a gain of +6dB and can drive a full 2VP-P video signal into one standard 150Ω video load. These buffers can drive either an AC- or DC-coupled load such that the blanking level voltage after the backmatch resistor is less than 1V. The video inputs feature a transparent clamp for AC- and DC-coupled input signals. If the input signal does not go below ground, the input clamp is inactive, thus enabling DAC outputs to be DC-coupled to the input. The device operates from a single +5V supply, is offered in the upper commercial 0°C to +85°C temperature range, and is available in a small 8-pin SO package.

Specially suited for standard-definition video signals, such as composite and luma, these devices are ideal for a wide range of applications such as cell phones and security/CCTV cameras. Video signals should be DC-coupled into the MAX9517 input and AC-coupled into the MAX9524 input. The MAX9517/MAX9524 have two single-pole, single-throw (SPST) analog switches that can be used to route stereo audio, video, or digital signals. The reconstruction filter typically has ±1dB passband flatness at 9MHz and 52dB attenuation at 27MHz. The amplifiers have a gain of 2V/V, and the outputs can be DC-coupled to a load of 75Ω, which is equivalent to two video loads. The outputs can be AC-coupled to a load of 150Ω, which is equivalent to one video load. The MAX9517/MAX9524 operate from a 2.7V to 3.6V single supply and are specified over the -40°C to +125°C automotive temperature range. The MAX9517/MAX9524 are available in a small 12-pin TQFN (3mm x 3mm) package.

The MAX11503 is a low-power video amplifier with a Y/C summer and chroma mute. The device accepts an S-video or Y/C input and sums the luma (Y) and chroma (C) signals into a composite CVBS signal which can be connected directly to a TV monitor. The MAX11503 drives two terminated 75Ω video coax cables. The MAX11503 features include chroma mute, power save, and SAG correction. Chroma mute disables the chroma buffer. If the device is used to combine Y and C signals in a camera application, the chroma mute may be used in low-light situations. This removes all chroma including burst which causes a downstream composite video decoder to interpret the video signal as luminance only, thus improving image quality. SAG correction allows small output capacitors to be used in AC-coupled output applications. The MAX11503 operates from a single 2.7V to 5.25V supply, is specified over the extended -40°C to +85°C temperature range, and is available in a small 8-pin µMAX® package.

These video filters are ideal for anti-aliasing and DAC smoothing in applications such as set-top boxes, digital video recorders, DVD players, and personal video recorders. The MAX11506/MAX11507 video inputs feature a transparent clamp compatible with AC- and DC-coupled input signals and allow DAC outputs to be directly coupled. The filters provide -3dB bandwidth of 9.0MHz for the SD filters and 33MHz for the HD filters. Each channel includes an output buffer with a gain of +6dB capable of driving 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. DC-coupling eliminates bulky coupling capacitors. The MAX11506 offers a flat passband while the MAX11507 features 0.8dB peaking on the three SD-only channels to compensate for system roll-off. The MAX11506/MAX11507 operate from a single +5V supply and are available in the 0°C to +70°C commercial temperature grade. The MAX11506/MAX11507 are offered in the 16-pin QSOP package.

The MAX9532 DirectDrive® video filter amplifier is specifically designed to work in harsh environments such as automobiles. The MAX9532 provides integrated short-to-battery protection, allowing the output of the device to survive shorts up to 18V. Maxim’s DirectDrive technology eliminates large output coupling capacitors and sets the output video black level near ground. DirectDrive requires an integrated charge pump and an internal linear regulator to create a clean negative power supply so that the amplifier can pull the sync below ground. The charge pump injects so little noise into the video output that the picture is visibly flawless. The MAX9532 features an internal reconstruction filter that smoothes the steps and reduces the spikes on the video signal from the video digital-to-analog converter (DAC). The reconstruction filter typically provides ±1dB passband flatness of 9.5MHz and 42dB attenuation at 27MHz. The input of the MAX9532 can be directly connected to the output of a video DAC. The MAX9532 also features a transparent input sync-tip clamp, allowing AC-coupling of input signals with different DC biases. The MAX9532 features an internal fixed gain of 4V/V. The input full-scale video signal is nominally 0.5VP-P, and the output full-scale video signal is nominally 2VP-P. The short-to-battery protection utilizes an internal switch in series with the amplifier output. When the MAX9532 detects that the output is short circuited to the battery voltage
