Reconstruction filter for standard-definition video paths
Its 7.9 MHz -3dB bandwidth is tailored for standard-definition video applications — think composite (CVBS), S-Video, or SDI output stages where you need to clean up the DAC's stair-step artifacts before the line driver. The rail-to-rail output lets it swing the full video signal without headroom issues at 3.3 V single supply, which matters when the DAC reference is also 3.3 V and you cannot afford a clipping artifact on sync tips.
Supply range and current budget
Runs from a single 2.5 V to 3.6 V rail, drawing 4.7 mA typical supply current. No dual supplies needed — one clean 3.3 V rail and a 1 µF decoupling cap at the pin is the usual recipe. At 4.7 mA it is not a micropower part, but for a video filter in a camera module or set-top box that current is a rounding error in the total system budget. The exposed pad on the 16-UFQFN package needs a via stitch to the ground plane to keep the junction temperature in check if the ambient runs warm.
Package and footprint reality
The 16-LFCSP-UQ (3x3) package is a 0.5 mm pitch QFN-style land pattern. The exposed pad is the main thermal path and also the ground connection — the datasheet layout note (not reproduced here) calls for a 2x2 array of 0.3 mm vias under the pad. If your reflow profile is set for standard lead-free, the 3x3 mm body reflows cleanly; just watch the paste coverage on the center pad to avoid voids that lift the part during wave-solder.
Lifecycle and compliance
No PCN or obsolescence letter has been issued for this order code as of the current date.
What the 7.9 MHz bandwidth means for your video path
The 7.9 MHz -3dB bandwidth is the key selection parameter. Standard-definition video (PAL/NTSC) has a luminance bandwidth around 5-6 MHz; this filter passes that cleanly while rolling off above 7.9 MHz to suppress the DAC's sampling images. If you are feeding a 1080p HDMI encoder or a VGA DAC, the 7.9 MHz corner is too low — you would alias the higher-frequency content. But for CVBS, S-Video, or SD-SDI outputs this is the right pole. The single-pole roll-off shape means the stopband attenuation is modest; if you need sharper rejection at 27 MHz (the DAC clock), cascade a second-order passive LC after this stage.
