The recommended power-on sequence is to apply VDD (1.8V) first, followed by VIO (3.3V) and then the clock signal. This ensures proper device initialization and prevents latch-up.
To optimize the clock tree, use a clock buffer (e.g., SN74LV07) to drive the clock signal, and ensure the clock signal is routed close to the device to minimize skew and jitter.
The maximum allowed capacitance on the VDD pin is 10nF. Exceeding this value may cause power-on reset issues or affect device operation.
No, the TMS320VC5402PGE100 is not 5V tolerant. It requires a 1.8V power supply (VDD) and 3.3V I/O voltage (VIO). Using a 5V power supply may damage the device.
Use a reset supervisor IC (e.g., TLV7031) to generate a clean reset signal. Ensure the reset signal is asserted for at least 10ms to allow the device to properly reset.
