Fairchild’s video filter/drivers improve image quality

South Portland, Maine. — Fairchild Semiconductor Inc.'s family of highly integrated video filter/drivers boost image quality in DVD, LCD, TV, set-top box and other digital consumer products.

Featuring fully integrated functionality, these multi-channel devices offer video designers an active approach that provides a number of design benefits. Compared to typical passive approaches, the FMS6143, FMS6145 and FMS6146 significantly decrease test and design time, reduce inventory and increase image quality.

These integrated video filter/drivers also eliminate the need for multiple discrete components. For example, the 6-channel FMS6146 replaces as many as 80 parts to help designers lower pick-and-place design costs and reduce board space by up to 20% in video applications.

“Fairchild's integrated video filter/drivers offer more compact and reliable alternatives over discrete passive filter solutions, opening up new opportunities in high-volume applications,” said Ben Takada, Fairchild's application engineering manager for video products.

The 3-, 5- and 6-channel, 4th order filter/drivers improve image quality when used to replace discrete products in traditional 3rd order passive solutions. Compared to passive designs, they provide better inband and stopband filter characteristics that reduce artifacts in video signals and result in higher image quality. By providing 8 MHz cut-off frequency and 48-dB stopband attenuation, these devices meet standard definition (SD) video requirements, while allowing them to be used as anti-aliasing or reconstruction video out filter drivers. Internal diode clamps and bias circuitry enable the video filter/drivers to accommodate AC- or DC-coupled input signals. The outputs on each device can drive AC- or DC-coupled single (150Ω) or dual (75Ω) coaxial cable loads, eliminating the need for expensive output coupling capacitors and reducing design cost.

The FMS6143, FMS6145 and FMS6146 are available in SOIC and TSSOP packages. These products are lead-free (Pb-free) and meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020B and are compliant with the European Union requirements that will take effect in 2005.

Available now, with delivery in four weeks ARO, pricing for the FMS6143 (3-channel, SOIC), FMS6145 (5-channel, TSSOP), and FMS6146 (6-channel, TSSOP) is 50 cents, 68 cents, and 76 cents, respectively, in 1,000-piece quantities.
