The recommended power-up sequence is to apply VDD (1.2V to 1.4V) first, followed by VDDA (1.2V to 1.4V), and then VDDS (1.2V to 1.4V). This ensures proper device operation and prevents latch-up.
To optimize the clock tree, use the clock domain crossing (CDC) feature to minimize clock skew and ensure proper synchronization between clock domains. Additionally, use the clock gating feature to reduce power consumption by turning off clocks to idle modules.
The maximum operating temperature range for the TMS320VC5470ZHKA is -40°C to 105°C. However, it's recommended to operate the device within the industrial temperature range of -40°C to 85°C for optimal performance and reliability.
To implement a DDR memory interface, use the DDR2/DDR3 interface module and follow the guidelines provided in the TMS320VC5470ZHKA DDR2/DDR3 Interface User's Guide. Ensure proper signal integrity, clock synchronization, and timing closure to achieve reliable operation.
Follow the guidelines provided in the TMS320VC5470ZHKA PCB Layout and Routing Guidelines document. Key recommendations include using a 4-layer PCB, separating analog and digital signals, and minimizing signal lengths and vias to reduce noise and improve signal integrity.
