To convert between Y, R-Y, B-Y and HSV, the TMC2272A
isn’t needed at all; simply use the TMC2330A. To convert
between HSV and any other format, use the TMC2330A to
translate between HSV and Y, R-Y, B-Y, and use the
TMC2272A to translate between Y, R-Y, B-Y and the other
format. See Figures 8 and 9.

Notes:
1. Connect TMC2272A MSBs (Bits 11) to TMC2330A MSBs (Bits 15) and also to TMC2330A Bits 14-11. Connect
TMC2272A LSBs (Bits 10-0) to TMC2330A LSBs (Bits 10-0). TMC2330A output bits 14-11 are overflow.
2. TMC2272A Y

used to signify the intensity components.
The assignment of components to TMC2272A inputs and outputs may be altered through the selection of appropriate
coefficients.

Input Interpolation/Output Decimation and
Filtering
In some applications the two color-difference signals (R-Y/B-Y
or Cr/Cb, for example) are transmitted at one-half the rate of
the luminance (Y) signal. These two color-difference signals
are often multiplexed to one signal which is at the same sample
rate as the luminance signal.
In many applications, if the color difference signals are
already band-limited, it is satisfactory to use the same color
difference sample for each two luminance samples. Little
improvement is obtained with a simple averaging ([A+B]/2)
interpolation filter. If the color difference signal is not band-
limited, either of these two methods may yield unsatisfactory
results due to aliasing. In this case, a Fairchild TMC2242B
digital low-pass (half-band) interpolating filter will correctly
band-limit each color difference signal as it is interpolated.
