San Jose, Calif. August 30, 2004 Fairchild Semiconductor offers the combined functionality of high definition (HD), progressive scan (PS), and standard definition (SD) filters all within the FMS6407 video filter/driver.
The FMS6407 features a triple sixth order filter with selectable 30-MHz, 15-MHz, or 8-MHz 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 (80-MHz) PC applications. The FMS6407 is suited for removing high frequency noise prior to digitizing the signal (anti-aliasing), or for removing artifacts introduced during D/A conversion in the encoder (reconstruction filtering) in LCD TV, set-top box, DVD and HD/Blu-ray applications.
The FMS6407 offers 2 to1 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 dB or 6 dB, which can drive 1-Vpp or 2-Vpp signals into AC- or DC-coupled terminated video loads. The AC-coupled inputs include DC restore and bias circuitry. Other features include SD/PS/HD stopband attenuations of 56 dB, 48 dB, 40 dB, 0.26% differential gain, and a 0.11° 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."
This lead-free product meets 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.
In a 20-pin TSSOP package, pricing for the FMS6407 is $1.52 in 1,000-piece quantities. Samples are available now with delivery eight weeks ARO.
