| www.fairchildsemi.com Application Note 60 TMC22x5y input data ranges 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.
