Description

The FMS6151 low-cost integrated video filter is intended

to replace passive LC filters and drivers in low-voltage

portable video applications. The 5th-order filter provides

better image quality compared to typical 2nd- and 3rd-

order passive solutions.

The FMS6151 is intended to be directly driven by a DC-

coupled DAC output. The output can drive an AC- or DC-

coupled doubly terminated coax (150Ω) load. DC-coupling

the output removes the need for an expensive output

coupling capacitor. If an AC-coupled output is needed, the

SAG correction circuit can be used to reduce the AC out-

put coupling capacitor value. Input DC levels are offset by

approximately 100mV. This internal level shift is incorpo-

rated to prevent sync pulse clipping.

Offering SAG correction, 6dB fixed gain, and a 5th-order

low-pass filter in a space-saving MicroPak™ package

makes the FMS6151 well suited for space-sensitive appli-

cations, such as cellular phones and digital cameras.
