Video filter has the whole in one
The FMS6407 is billed as the only video filter/driver offering the combined functionality of high definition (HD), progressive scan (PS) and standard definition (SD) filters - all in one chip
The FMS6407 features a triple 6th-order filter with selectable 30, 15 or 8MHz cutoff frequencies, making this device flexible enough to be used in a broad range of video applications. For added capability, these filters can be bypassed allowing the output amplifiers to accommodate higher bandwidth (80MHz) PC applications.

The FMS6407 is an ideal solution for anti-aliasing, removing high frequency noise prior to digitising the signal, or for reconstruction filtering, removing artefacts introduced during D/A conversion in the encoder in LCD TV, set-top box, DVD and HD/Blu-ray applications.
The flexible FMS6407 offers 2:1 multiplexers to accommodate multiple video formats (YPbPr/RGB or YPbPr/YC-CV) and will automatically adjust sync tip clamp voltages to the appropriate levels, depending on the video format selected.
All three outputs on the FMS6407 are driven by amplifiers with selectable gains of 0 or 6dB, which can drive 1 or 2V peak-peak signals into AC- or DC-coupled terminated video loads.
The AC-coupled inputs include DC restore and bias circuitry.
Other important features include SD/PS/HD stopband attenuations of 56/48/40dB, 0.26% differential gain, and a 0.11 degree differential phase.
"The FMS6407 takes our leading edge video filter/driver technology and adds even more functionality", said Ben Takada, Fairchild's Business Development Director for Video Products.
"With the FMS6407, we now offer on-chip clamp select to handle the various video formats, a solution for progressive scan (480p) and PC applications, along with standard definition (NTSC/Pal/Secam) and high definition (1080i/720p) products, all in the same device".
The FMS6407 is available in a 20-pin TSSOP package.
This lead-free (Pb-free) product meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020B and is compliant with the European Union requirements, which will take effect in 2005.
A demo/evaluation board (FMS6407DEMO) is available to illustrate the full performance of the FMS6407.
