Description
The FMS6419 offers comprehensive 鏗乴tering for set top box
or DVD applications. This part consists of a triple 6th order
鏗乴ter with selectable 30MHz or 8MHz frequencies.
A 2-to-1 multiplexer is provided on each 鏗乴ter channel. The
triple 鏗乴ters are intended for either YUV or RGB signals. All
channels accept DC coupled ground-referenced 1V signals.
The 鏗乴ters provide 2Vpp signals into AC coupled terminated
loads. The low-pass 鏗乴ters are powered by 3.3V and the out-
puts by 5.0V.
Applications
