15.14. FMS6145
15.14.1. General Description
The FMS6145 Low-Cost Video Filter (LCVF) is intended to replace passive LC ¿ OWHUV
and drivers with a low-cost integrated device. Five 4th-order ¿ OWHUV provide improved
image quality compared to typical 2nd or 3rd-order passive solutions. The FMS6145
may be directly driven by a DC-coupled DAC output or an AC-coupled signal. Internal
diode clamps and bias circuitry may be used if AC-coupled inputs are required. The
outputs can drive AC- or DC-FRXSOHGVLQJOHȍRU GXDOȍORDGV'&FRXSOLQJWKH
outputs removes the need for output coupling capacitors. The input DC levels are offset
approximately +280mV at the output.
