Clock Recommendations for the DM643x EVM
Texas InstrumentsThe DM643x evaluation module (EVM) requires several clock frequencies to run the system properly. The current clocking proposal of the low-cost EVM consists of the VCXO chip PI6CX100-27W the PLL chip PLL1705 several bus drivers and a few oscillaors and crystals. This application report discusses several optimized clocking proposals with the Texas Instruments new clock drivers and recommends a m

Heat Sinking- TO-3 Thermal Model
Texas InstrumentsA critical issue with all semiconductor devices is junction temperature (TJ). TJ must be kept below its maximum rated value typically 150°C. The lower the junction temperature the better. The thermal circuit shown allows temperature to be estimated with simple calculations. The temperature rise across each interface is equal to the total power dissipated in the device ti

Hot Plug-In In-Rush Current Limiting Circuits for PT3100/4100/3320 DC-DC Convert (Rev. A)
Texas InstrumentsIn-rush current is the initial current that flows to the converter’s input de-coupling capacitor(s) when the host board assembly is connected to an active input power source. The magnitude of the in-rush current is high and can induce arcing, transients, and erosion of the connector. Limiting the in-rush current allows the host board assembly to be safely plugged into a live system backplane connector, such as those powered from a -48V central office power supply.
