If reducing capacitance due to the demands of miniaturization or the like, check the SAG characteristic for an alternating black and white bounce signal *1, H-bar signal *2, or other signal for which a SAG effect readily occurs and use a capacitance that satisfies the demands of the set being used. As a reference, try the combinations shown below when reducing capacitance. As the capacitance of the VOUT capacitor is made smaller, SAG becomes greater. *1,*2: TG-7 U705 unit or other REV.

However, since direct current will flow in a set connected on the opposite side due to eliminating the output coupling capacitor, pay close attention to the specifications of what is connected in conjunction with using it. Moreover, characteristics such as circuit current, differential gain, and differential phase differ as shown below. With Output Coupling Without Output Coupling Capacitor Capacitor Circuit Current (If no signal) 7.1 mA 7.8 mA Circuit Current (If color bar signal output) 8.3 mA 14.3 mA Differential Gain (DG) 0.7% 1.0% Differential Phase (DP) 0.7° 0.3° The values shown above are reference values. They are not guaranteed values Parameter ■Caution of use 1) Absolute maximum ratings If applied voltage, operating temperature range, or other absolute maximum ratings are exceeded, the LSI may be damaged. Do not apply voltages or temperatures that exceed the absolute maximum ratings. If you think of a case in which absolute maximum ratings are exceeded, enforce fuses or other physical safety measures and investigate how not to apply the conditions under which absolute maximum ratings are exceeded to the LSI. 2) GND potential Make the GND pin voltage such that it is the lowest voltage even when operating below it. Actually confirm that the voltage of each pin does not become a lower voltage than the GND pin, including transient phenomena. 3) Shorts between pins and mis-installation When mounting the LSI on a board, pay adequate attention to orientation and placement discrepancies of the LSI. If it is mis-installed and the power is turned on, the LSI may be damaged. It also may be damaged if it is shorted by a foreign substance coming between pins of the LSI or between a pin and a power supply or a pin and a GND. 4) Operation in strong magnetic fields Adequately evaluate use in a strong magnetic field, since there is a possibility of malfunction. 5) Input terminating resistance Since it will become easy to come to the synch-tip part of a video output signal out of ripple if terminus impedance of an input terminal (5PIN) is made high, please use it less than 1.5kohm after sufficient evaluation also including the temperature characteristic. 6) Bypass capacitor To minimize the risk of high-frequency oscillation, the power supply's bypass capacitor should be placed as close as possible to the Vcc pin.
