Buffered RGB to Color-Difference Matrix
Two LT1398s can be used to create buffered color-
difference signals from RGB inputs (Figure 8). In this
application, the R input arrives via 75
coax. It is routed
to the noninverting input of LT1398 amplifier A1 and to
a 1082
resistor R8. There is also an 80.6 termination

resistor R11, which yields a 75
input impedance at the
R input when considered in parallel with R8. R8 connects
to the inverting input of a second LT1398 amplifier (A2),
which also sums the weighted G and B inputs to create a
–0.5 Y output. LT1398 amplifier B1 then takes the
–0.5 Y output and amplifies it by a gain of –2, resulting
in the Y output. Amplifier A1 is configured in a noninvert-
ing gain of 2 with the bottom of the gain resistor R2 tied
to the Y output. The output of amplifier A1 thus results in
the color-difference output R-Y.
The B input is similar to the R input. It arrives via 75
coax, and is routed to the noninverting input of LT1398
amplifier B2, and to a 2940
resistor R10. There is also
a 76.8
termination resistor R13, which yields a 75
input impedance when considered in parallel with R10.
R10 also connects to the inverting input of amplifier A2,
adding the B contribution to the Y signal as discussed
above. Amplifier B2 is configured in a noninverting gain
of 2 configuration with the bottom of the gain resistor R4
tied to the Y output. The output of amplifier B2 thus
results in the color-difference output B-Y.
