5 / 13 page LA7138M No.A0220-5/16 Design Guarantee Items at Ta = 25 °C Ratings Parameter Symbol Conditions min typ max Unit 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. -65 -60 dB Video S/N ratio SN 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. -80 -78 dB Differential gain DG Enter the 1Vp-p standard stair step signal (color) to obtain pin 11 = OPEN. Measure the differential gain of the output signal, with the output pin part shown in the measuring circuit diagram inserted. 0.5 2 % Differential phase DP Enter the 1Vp-p standard stair step signal (color) to obtain pin 11 = OPEN. Measure the differential phase of the output signal, with the output pin part shown in the measuring circuit diagram inserted. -1 0 1 dB For Y/C-MIX (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. -65 -60 dB Video S/N ratio SN Enter the Y signal with 100% white and add pin 11 = 3.3V. Measure S/N of the output signal. * Refer to Note 1. -74 -72 dB Differential gain DG Enter the 761mVp-p standard stair step signal (color) to obtain pin 11 = 3.3V. Measure the differential gain of the output signal, with the output pin part shown in the measuring circuit diagram inserted. 4 5.5 % Differential phase DP Enter the 761mVp-p standard stair step signal (color) to obtain pin 11 = 3.3V. Measure the differential phase of the output signal, with the output pin part shown in the measuring circuit diagram inserted. -1 0.5 1.5 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.)
