Video 75 W Driver IC built in Charge Pump Circuit Overview AN13206A is a 75 Ω driver IC for video which can operate with power supply of 2.85 V. It can be used for direct DC coupling by a charge pump circuit which can get a sufficient output dynamic range from power supply of 2.85 V Features 1. Power Supply voltage : 2.85V, 75 Ω driver for 1-ch. Video signal. 2. Output capacitor is unnecessary by generatin g negative voltage from Charge Pump Circuit. 3. Supporting wide output dynamic range. 4. Adopting of small size non-leaded package. Mounting area : −45% (than conventional products), including shrinking the area of peripheral parts. 5. Output pin can be a high impedance. Additionally two switches ar e built-in, the output pin for a video signal is usable with other ICs . 6. Peripheral resistor of 75 Ω is possible to use as terminating resistance. (output pin is shorted to GND by internal switch.) Applications y Video 75 Ω driver for the mobile devices. (For mobile phone, digital still camera etc.) Package y 12 pin Fine Pitch Land Grid Array Package (LGA Type) Type y Silicon monolithic Bi-CMOS IC
Note) The Above circuit and peripheral part’s constants shows an example of design, but it is not guaranteed as those for mass production sets.

(2) The technical information described in this book is intended only to show the main characteristics and application circuit examples of the products, and no license is granted under any intellectual property right or other right owned by our company or any other company. Therefore, no responsibility is assumed by our company as to the infringement upon any such right owned by any other company which may arise as a result of the use of technical information described in this book. (3) The products described in this book are intended to be used for standard applications or general electronic equipment (such as office equipment, communications equipment, measuring instruments and household appliances). Consult our sales staff in advance for information on the following applications: Special applications (such as for airplanes, aerospace, automobiles, traffic control equipment, combustion equipment, life support systems and safety devices) in which exceptional quality and reliability are required, or if the failure or malfunction of the prod- ucts may directly jeopardize life or harm the human body. Any applications other than the standard applications intended. (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.
