Texas Instruments provides a recommended PCB layout in the application note SLUU287, which includes guidelines for component placement, routing, and grounding to minimize EMI and noise.
Proper power supply decoupling is crucial. Use a 10uF ceramic capacitor and a 1uF ceramic capacitor in parallel, placed close to the device, and connected to the power pins. Additionally, ensure a low-impedance power supply and a solid ground plane.
The CDCP1803RGER can support clock frequencies up to 200 MHz, but the actual frequency limit depends on the specific application, PCB layout, and signal integrity.
The CDCP1803RGER can be configured for differential or single-ended clock input through the CLK_SEL pin. For differential input, tie CLK_SEL to VCC, and for single-ended input, tie CLK_SEL to GND.
The recommended termination scheme for the CDCP1803RGER output is a 50-ohm series resistor and a 50-ohm parallel terminator to the load. This ensures signal integrity and minimizes reflections.
