A good PCB layout for the CDCLVP1102RGTT involves keeping the input and output traces short and symmetrical, using a solid ground plane, and placing decoupling capacitors close to the device. TI provides a recommended layout in the datasheet and application notes.
The output termination depends on the load impedance and the desired signal integrity. For a 50-ohm load, a series 51-ohm resistor and a parallel 100-nF capacitor are recommended. For other loads, consult the datasheet and application notes for guidance.
The CDCLVP1102RGTT can operate up to 1.5 GHz, but the maximum clock frequency depends on the specific application, PCB layout, and output loading. Consult the datasheet and application notes for guidance on clock frequency selection.
To minimize jitter and ensure signal integrity, use a low-jitter clock source, keep the clock signal path short and shielded, and use a high-quality PCB material. Additionally, use the device's built-in jitter attenuation feature and follow the recommended layout and termination guidelines.
The power consumption of the CDCLVP1102RGTT depends on the operating frequency, output loading, and supply voltage. Typically, it consumes around 150-200 mW at 1.5 GHz with a 3.3-V supply. Consult the datasheet for detailed power consumption information.
