The recommended power-on sequence is to apply VDD (core voltage) first, followed by VIO (I/O voltage) and then the clock signal. This ensures proper device operation and prevents latch-up.
To optimize the clock tree, use a clock buffer to drive the clock signal, and ensure that the clock signal is routed close to the device to minimize skew. Also, use a clock distribution network to reduce jitter and ensure that all clock domains are properly synchronized.
The maximum allowed clock frequency for the TMS320LC542PBK1-50 is 50 MHz, as specified in the datasheet. However, the actual achievable frequency may be lower depending on the system design, PCB layout, and environmental conditions.
To handle thermal management, ensure good airflow around the device, use a heat sink if necessary, and avoid blocking the airflow with components or obstacles. Also, consider using thermal interface materials to improve heat transfer between the device and the heat sink.
The recommended PCB layout strategy is to use a multi-layer board with a solid ground plane, route critical signals on the top layer, and use vias to connect signals between layers. Also, ensure that the device is placed in a corner of the board to minimize noise and interference.
