3-ch. video driver IC supporting HD with charge pump Overview AN13208A is a 75 Ω video driver IC supporting HD (high-definition) which can operate by 3.25 V of supply voltage. 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.

Usage Notes 1. Carry out the thermal design with sufficient margin such that the power dissipation will not be exceeded, based on the conditi ons 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 Pin 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.

(4) The products and product specifications described in this book are subject to change without notice for modification and/or im- provement. At the final stage of your design, purchasing, or use of the products, therefore, ask for the most up-to-date Product Standards in advance to make sure that the latest specifications satisfy your requirements. (5) When designing your equipment, comply with the range of absolute maximum rating and the guaranteed operating conditions (operating power supply voltage and operating environment etc.). Especially, please be careful not to exceed the range of absolute maximum rating on the transient state, such as power-on, power-off and mode-switching. Otherwise, we will not be liable for any defect which may arise later in your equipment. Even when the products are used within the guaranteed values, take into the consideration of incidence of break down and failure mode, possible to occur to semiconductor products. Measures on the systems such as redundant design, arresting the spread of fire or preventing glitch are recommended in order to prevent physical injury, fire, social damages, for example, by using the products. (6) Comply with the instructions for use in order to prevent breakdown and characteristics change due to external factors (ESD, EOS, thermal stress and mechanical stress) at the time of handling, mounting or at customer's process. When using products for which damp-proof packing is required, satisfy the conditions, such as shelf life and the elapsed time since first opening the packages.
