Video filters have all formats covered
A family of video filter/drivers claim the best combination of filtering flexibility, allowing designers to maintain high performance in the video signal path while optimising system cost.
Reinforcing its position as the number one supplier of integrated video filter/drivers for the digital set-top box market, Fairchild Semiconductor has released a family of video filter/drivers with the best combination of filtering flexibility, allowing designers to maintain high performance in the video signal path while optimising system cost With selectable standard definition (SD), progressive scan (PS) and high-definition (HD) filtering capability, this video filter/driver family allows designers to tailor the right combination of two filter frequencies to their specific design requirements

Dual-output buffer for DDR SDRAM modules
Fairchild Semiconductor has introduced a dual-output registered buffer for 184-pin, 2.5V PC200/PC266, 72bit-wide registered double data rate (DDR) SDRAM modules.
Bus hold makes logic more predictable
Fairchild Semiconductor has made a number of additions to its LCX family, the logic industry standard for 3.3V applications.
These highly integrated 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%.
In addition to set-top boxes, these devices are ideal for use in DVDs, digital TVs and other consumer video products.
Fairchild's FMS6690, FMS6246 and FMS6346 six-channel, sixth order video filter/drivers stand apart from competing devices by allowing designers to select the combination of SD, PS and HD filters best suited to their system needs.

MOSFET is ready for high-voltage car batteries
The new FDB06AN08A1 UltraFET trench MOSFET from Fairchild Semiconductor is designed for 42V automotive battery applications requiring full device capability at low gate drive voltages.
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 device integrates selectable filters, input clamps and fixed gain (6dB) output drivers into a single TSSOP package.
They also reduce space by offering the choice of AC- or DC-coupled inputs and outputs, as DC-coupled outputs eliminate the need for large AC-coupling capacitors.
"Consumer video applications require space efficiency, high performance and design ease to speed time-to-market and assure system reliability", said Jeremy Tole, Fairchild's Product Marketing Manager for Video Products.
"Fairchild's new video filter family offers video designers the most design options available compared with 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 12 ESD diodes".
Each one of the video filter/drivers in the family offers a range of device options.
The FMS6690 offers three channels with fixed 8MHz filters and three that are selectable between PS and HD (15/32MHz), ideal for high-definition television (HDTV) applications.
The FMS6246 offers three channels with fixed 8MHz filters and three that are selectable between SD and PS (8/15MHz), targeting DVD players.
And the FMS6346 offers three channels with fixed 8MHz filters and three that are selectable between SD and PS (8/32MHz), best suited to set-top box designs.
The FMS6690, FMS6246 and FMS6346 come in lead (Pb)-free 20-pin TSSOP packages.
These products meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020B and are compliant with the European Union requirements now in effect.
Samples are available now, with delivery 8 weeks ARO.
