Except for Y/C-MIX (VCCA = 9.0 to 13.0V, VCCB = 7.5 to 8.5V)
Channel crosstalk
CT
The signal which becomes 1Vp-p at f = 4MHz and with the output in
C connection is entered in other channels. Measure the magnitude
of monitor channel output pins at 4MHz and specify the ratings as a
ratio relative to the magnitude of output pin of other channels at
4MHz.

Enter the Y signal with 100% white and apply 3.3V to pin 11.
Measure S/N of the output signal.
* Refer to Note 1.

dB
* Note 1) Since the noise in IC is dependent on the stability of regulator, it is recommended to connect a 470
µF capacitor when the S/N ratio of –80dB is to be
secured for controls other than Y/C-MIX. To secure the S/N ratio of -74dB for Y/C-MIX, set the supply voltage to 8V (VCCB) and apply 8V also to this
pin. (See the test circuit B.)
