The recommended power-on sequence is to apply VDD (1.2V) 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., SN74LVC2G04) to drive the clock signal, and ensure that 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 performance.
No, the TMS320VC33PGEA120 is designed to operate at 1.2V (VDD) and 3.3V (VIO). Using a 5V power supply may damage the device or affect its performance.
Use a reset IC (e.g., TLV703P) with a capacitor (e.g., 10uF) to ensure a clean reset signal. The reset signal should be asserted for at least 10ms to ensure proper device reset.
