TMC22x5y input data ranges

www.fairchildsemi.com
There is no fixed input data range to the TMC22x5y family
of digital decoders, as the programmable output matrix
allows up to 6dB of gain on the luminance and color differ-
ence signals. The following data ranges for 100% composite
and YC color bar inputs is for reference only.
