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.
