Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good high-frequency design practices, such as using a solid ground plane, minimizing trace lengths, and using 50-ohm transmission lines to ensure optimal performance.
The LMK1D2102RGTT has a programmable output frequency, which can be set using the SPI interface. The device has a 32-bit frequency control register that allows you to set the output frequency from 10 MHz to 2.1 GHz. Refer to the datasheet for the specific register settings and calculation formulas.
The phase noise performance of the LMK1D2102RGTT is not explicitly stated in the datasheet, but according to Texas Instruments' application notes, the device typically exhibits a phase noise of around -110 dBc/Hz at 10 kHz offset and -140 dBc/Hz at 100 kHz offset for a 1 GHz output frequency.
Yes, the LMK1D2102RGTT can be used as a clock source for an FPGA. The device provides a low-jitter clock output that meets the requirements of most FPGAs. However, ensure that the output frequency and voltage levels are compatible with your specific FPGA requirements.
The LMK1D2102RGTT does not have built-in FM or AM capabilities. However, you can implement modulation using external circuitry or by using the device's SPI interface to control the output frequency or amplitude. Consult the datasheet and application notes for more information on implementing modulation schemes.
