Design Notes
Ensure stable power supply by placing 100nF decoupling capacitors close to each VDD pin and a 10uF bulk capacitor at the main supply. The SR6G7C6 operates from 3.3V to 5V, so verify the voltage regulator output is within this range. Use a low-dropout regulator (LDO) for clean power in noise-sensitive applications.
For the crystal oscillator, place it close to the MCU pins and keep traces short to minimize parasitic capacitance. Use a ground plane underneath to reduce noise. For high-speed interfaces like Ethernet, maintain controlled impedance traces (e.g., 50 ohms) and keep differential pairs matched in length.
The SR6G7C6 can dissipate significant power at 240 MHz. Ensure adequate thermal management by using a thermal pad on the PCB and providing vias to a copper pour. The LQFP-176 package has a thermal resistance of approximately 20°C/W; calculate junction temperature to ensure it stays below 125°C.
