Negative voltages generated by built-in charge pump circuit enable DC direct output, and output capacitor which is needed previously is not required. Also, it improves the output dynamic range which was difficult by a single supply. Furthermore, it incorporates various filters for D pin outputs and control switches, which allows 75 Ω driving by 3 output systems of Cy, Cb, Cr or Py, Pb, Pr. Features Supply voltage 3.25 V, 75 Ω driver for 3-ch. video 3 output systems of Cy, Cb, Cr or Py, Pb, Pr Supports D4 (720P) 3 modes of filter selector switches Built-in stand-by mode Output capacitor is unnecessary by generating negative voltage from charge pump circuit.

Carry out the thermal design with sufficient margin such that the power dissipation will not be exceeded, based on the conditions of power supply, load and ambient temperature. The absolute maximum ratings are values which should not be exceeded in any use or test conditions. 2. Pay attention in the pattern layout in order to prevent damage due to short circuit between pins. In addition, refer to the Description for the pin configuration. 3. Be sure not to mount the LSI in the reverse direction onto the PCB. It might be damaged when the electricity is turned on. 4. Perform a visual inspection on the PCB before turning on the power supply, otherwise damage might happen due to problems such as a solder-bridge between the pins of the semiconductor device. Also, perform a full technical verification on the assembly quality, because the same damage possibly can happen due to conductive substances, such as solder ball, that adhere to the LSI during transportation. 5. Take notice in the use of this product that it might break or occasionally smoke when an abnormal state occurs such as power fault, i.e., output pins, Pin4 (CP negative voltage output), or Pin5 (SUB potential) short to the power supplies. And, safety measures such as an installation of fuses are recommended because the extent of the above-mentioned damage and smoke emission will depend on the current capability of the power supply. 6. When using the LSI for model deployment or new products, perform fully safety verification including the long-term reliability for each product. 7. This IC has a built-in charge pump which generates PCB voltage (negative voltage) inside the IC. As the fin of this IC is connected to the PCB, it might be damaged or emit smoke when a voltage including GND is applied.
