Video driver sends cell phone images to large displays

South Portland, Maine — Fairchild Semiconductor claims this is the smallest video filter/driver available for driving video images from cell phones to televisions, computer monitors or other large display products.

Packaged in a 6-terminal MicroPak package measuring 1.45 x 1.0 x 0.55-mm, the device's 5th order 8-MHz standard definition (SD) filter results in better image quality — and the 3.8-mA supply current with power down to 25 nA extends battery life, said Bob Vinton, Fairchild's product line manager, Signal Conditioning Products.

“One of the hottest applications on the horizon is driving a composite video signal from a cell phone to a TV or other large display product for easier viewing. But when this signal conversion takes place, frequency artifacts from the DAC reconstruction process can adversely affect the video image,” Vinton said. Fairchild's FMS6151 video filter/driver uses a 5th order Butterworth low-pass filter that provides better stop band attenuation compared to typical 2nd and 3rd order solutions, he said.

Other features of the FMS6151 filter include 2.7-V to 5-V operation, DC-coupled inputs, a choice of AC- or DC-coupled outputs, and 75-ohm cable drivers.

Pricing for the FMS6151 is 35 cents each in 1,000-piece quantities. Samples and demo boards are available now. Click here for the FMS6151 data sheet.
