Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the PLL1700E away from noisy components and traces. Additionally, use a low-ESR capacitor for the VCC pin and a 0.1uF capacitor for the VCO pin.
To optimize the PLL1700E for low power consumption, use the lowest possible input frequency, disable the PLL when not in use, and adjust the charge pump current to the minimum required value. Additionally, use a low-power mode if available.
The PLL1700E can operate up to 1700 MHz, but the maximum frequency range depends on the specific application and the quality of the external components used. It's recommended to consult the datasheet and application notes for specific frequency range limitations.
To troubleshoot PLL1700E-related issues, use a spectrum analyzer to measure the output frequency and jitter, and check the input clock signal quality. Also, verify that the PLL is properly configured and that the loop filter components are correct. Consult the datasheet and application notes for troubleshooting guidelines.
The PLL1700E is not specifically designed for radiation-hardened or high-reliability applications. However, Texas Instruments offers other PLL products that are designed for such applications. Consult the datasheet and application notes for specific information on radiation hardness and reliability.
