Clocking Recommendations for DM6446 Digital Video EVM with Sngle PLL (Rev. A)
The DM6446 (DaVinci™) Digital Video Evaluation Module (EVM) requires a number of clock frequencies to run the system properly. The current clocking proposal of this EVM consists of a VCXO chip PI6CX100-27W, a PLL chip PLL1705, several voltage level translators, and a few oscillators or crystals. This application report discusses an optimized clocking proposal with Texas Instruments new clock drivers and recommends a more integrated, high-performance, and cost-saving proposal with a minimum number of ICs.
