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, 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 appli-
cations such as cellular phones and digital cameras.
