A good PCB layout for the CSD13385F5 involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces connected to the device's pins. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To optimize the POR circuit, ensure that the power supply voltage (VDD) rises slowly and monotonically during power-up. A recommended POR circuit includes a voltage detector with a threshold voltage of around 1.8V, and a capacitor (e.g., 10nF) connected between the VDD pin and the voltage detector input.
The recommended clock frequency for the CSD13385F5 is between 10MHz and 40MHz. A higher clock frequency can improve the device's performance, but it also increases power consumption. A lower clock frequency can reduce power consumption, but it may affect the device's accuracy and response time.
The IVR output voltage (VREG) is internally regulated to 1.8V. To ensure proper operation, connect a 1uF capacitor between the VREG pin and the analog ground (AGND) pin. Additionally, ensure that the input voltage (VIN) is within the recommended range of 2.7V to 5.5V.
To minimize EMI and ensure EMC, use a shielded enclosure, keep the device away from high-frequency sources, and use a common-mode choke or ferrite bead on the power supply lines. Additionally, ensure that the PCB layout is optimized for minimal radiation and that the device is properly grounded.
