Fairchild Semiconductor launched a family of video filter/drivers with selectable standard definition (SD), progressive scan (PS) and high-definition (HD) filtering capability. These video filter/drivers were designed as an alternative to discrete solutions by replacing passive LC filters and drivers for board space savings of up to 50 percent. In addition to STBs, these devices are suitable for use in DVDs, DTVs and other consumer video products.

The FMS6690, FMS6246 and FMS6346 family of 6-channel, 6th order video filter/drivers allow designers to select the combination of SD/PS/HD filters best suited to their system needs. According to the company, these devices offer higher levels of integration than previously achievable by manufacturers requiring composite-video, S-video and component-video (YPbPr, YUV, RGB). To save space, each product integrates selectable filters, input clamps and fixed gain (6dB) output drivers into a single TSSOP package. They also aim to reduce space by offering the choice of AC- or DC-coupled inputs and outputs, since DC-coupled outputs eliminate the need for large AC-coupling capacitors.

Jeremy Tole, Fairchild's product marketing manager for video products, said that its new video filter family offers video designers the most design options available compared to discrete or similar solutions that require more space to achieve the same performance as one 20-pin TSSOP. "For instance, all six channels on each device achieve reliable, consistent performance, as opposed to discrete filter channels that can vary with RLC tolerance. Additionally, by offering 12kV of ESD protection, the customer is able to remove twelve ESD diodes," said Tole.

The products come in Pb-free 20-pin TSSOP packages. These video filter/drivers meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020B, and are compliant with the European Union requirements. Price is set at 83 cents for 1,000 pieces.
