APPLICATIONS Set-top boxes HDTVs Projectors DVD players/recorders Personal video recorders GENERAL DESCRIPTION The ADA4417-3 is a low cost, fully integrated, video The ADA4417-3 also has an output dc offset function that can operate in two states. When the DCO pin is tied to V , the reconstruction filter specifically designed for consumer high CC definition video. With 1 dB frequency flatness out to 38 MHz, video signal at the output is offset by 200 mV. When the DCO and 44 dB of rejection at 75 MHz, the ADA4417-3 can handle pin is tied to ground, the output dc level follows the input level. the most demanding HD video applications. The ADA4417-3 is available in a 10-lead MSOP package and is The ADA4417-3 operates on a single 3.3 V to 5 V supply. It is rated for operation over the extended industrial temperature well-suited for applications where power consumption is range of 40C to +85C. critical. A disable feature allows for further power conservation by reducing the supply current to 10 A (typical) when the device is not in use. With rail-to-rail output, it can be efficiently used on a 3.3 V supply, while providing the user with a 2 V p-p output. The buffers can drive two 75 terminated loads, either dc- or ac-coupled. Rev.
