A good PCB layout for the VFC110AP involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. Additionally, it's recommended to use a separate analog ground plane and to keep the power supply traces away from the analog signals.
The choice of input and output capacitors for the VFC110AP depends on the specific application and the desired performance. In general, X5R or X7R ceramic capacitors with a voltage rating of 10V or higher are recommended. The capacitance value should be chosen based on the desired filtering characteristics and the impedance of the input and output stages.
The maximum power dissipation of the VFC110AP is 1.4W. To ensure that it does not overheat, it's recommended to provide adequate heat sinking, such as a thermal pad or a heat sink, and to keep the device in a well-ventilated area. Additionally, the device should be operated within the recommended temperature range of -40°C to 125°C.
The VFC110AP can be configured for a specific output voltage and frequency by adjusting the values of the external resistors and capacitors. The output voltage can be set using the feedback resistors, while the frequency can be set using the oscillator resistors and capacitors. The specific values can be calculated using the equations provided in the datasheet or by using TI's online calculator tools.
The VFC110AP is designed to meet the EMI and EMC requirements of various regulatory standards, such as CISPR 22 and FCC Part 15. To ensure compliance, it's recommended to follow good PCB layout practices, use shielding and filtering where necessary, and to perform EMI and EMC testing during the design and validation process.
