Description
The FMS6151 low cost, integrated, video
fi
lter is intended
to replace passive LC
fi
lters and drivers in low voltage
portable video applications. The 5th order
fi
lter 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,
fi
xed gain of 6dB, and a 5th order
low pass
fi
lter in a tiny space saving package (Micropak)
makes the FMS6151 well suited for space sensitive appli-
cations such as cellular phones and digital cameras.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable
above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition,
extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute
maximum ratings are stress ratings only.
