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 signal integrity.
The CDCM1802RGTRG4 requires a 50-ohm output termination to ensure signal integrity. You can use a 50-ohm resistor in series with a capacitor to ground or a 50-ohm resistor to VCC, depending on your application's requirements.
The CDCM1802RGTRG4 can operate up to 1800 MHz, but the maximum clock frequency depends on the specific application and the quality of the clock signal. It's recommended to consult the datasheet and perform simulations to determine the maximum clock frequency for your specific use case.
To achieve low jitter performance, ensure that the clock input signal is clean and has a low jitter, use a high-quality crystal oscillator, and follow good PCB design practices, such as minimizing noise coupling and using a solid ground plane.
The power consumption of the CDCM1802RGTRG4 depends on the operating frequency, output load, and supply voltage. According to the datasheet, the typical power consumption is around 130 mW at 1800 MHz with a 3.3V supply voltage.
