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(150 Ω ) load. DC-coupling the output removes the need for an expensive output coupling capacitor. If an AC-cou- pled output is needed, the SAG correction circuit can be used to reduce the AC output coupling capacitor value. Input DC levels are offset by approximately 100mV. This internal level shift is incorporated to prevent sync pulse clipping. Offering SAG correction, fixed gain of 6dB, and a 5th order low pass filter in a tiny space saving package (Micropak) makes the FMS6151 well suited for space sensitive applications such as cellular phones and digital cameras.
