<br> == Introduction == This page serves as a repository of Complimentary Devices that can be paired with the OMAP-L138/L118/L108 SoC devices when integrating the device into a system. The Complementary Products listed here serve a wide range of functions such as: *Providing basic support functions for the SoC (power, clocking, etc.) *Expanding the interface options beyond the on-chip peripherals *Creating the link between the digital domains on the SoC to the system's analog/physical domains The Complementary Products are organized into functional categories, with the goal of showing several options and their respective Benefits. <br> == Analog Video Input == OMAP-L1x8 devices include a 8-/16-bit digital video input port (VPIF) that can be interfaced with a video decoder, or ADC, to bring analog SD video into the SoC. Before bringing the analog video into the ADC, it is also necessary to run it through an anti-aliasing filter to restrict the bandwidth before sampling. Below is a sample of SD video decoders and anti-aliasing filters that would be a good match for OMAP-L1x8 devices.

On the output of the ADC, it is also necessary to take the analog video through an amplifier and reconstruction filter to achieve the correct gain and remove the high-frequency images of the signal.

Clock generators/synthesizers can use a single crystal to produce many clock output frequencies using their internal PLLs.
