Fairchild Semiconductor International (South Portland, ME) announced its FMS6407, a video filter/driver offering the combined functionality of high definition (HD), progressive scan (PS) and standard definition (SD) filters in one chip. The FMS6407 features a triple sixth-order filter with selectable 30 MHz, 15 MHz or 8 MHz cutoff frequencies, making the device flexible enough to be used in a broad range of video applications.
The FMS6407 offers 2 to 1 multiplexers to accommodate multiple video formats and will automatically adjust sync-tip clamp voltages to the appropriate levels. 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-coupled 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 dB/48 dB/40 dB, 0.26% differential gain, and a 0.11 degree differential phase.
The FMS6407 is available in a 20-pin TSSOP package. The lead-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. Pricing for the FMS6407 is $1.52 for 1,000-piece quantities. Samples are available now, with delivery in eight weeks ARO.
