The LTC6951SW-3.3 can support clock frequencies up to 3.2 GHz, but the maximum frequency is dependent on the specific application and layout. It's recommended to consult with the datasheet and application notes for more information.
To optimize power supply decoupling, use a combination of high-frequency and low-frequency capacitors (e.g., 100nF and 10uF) placed close to the device, and ensure that the power supply lines are well-bypassed and decoupled from the digital and analog signals.
The recommended termination scheme for the LTC6951SW-3.3 is a 50Ω differential termination to match the output impedance of the device. This can be achieved using a 50Ω resistor in series with a capacitor to ground.
To minimize jitter and phase noise, use a high-quality clock source, ensure a stable power supply, and optimize the PCB layout to minimize noise coupling and radiation. Additionally, consider using a clock jitter cleaner or a phase-locked loop (PLL) to further reduce jitter and phase noise.
The maximum output amplitude of the LTC6951SW-3.3 is 1.3Vpp differential, but this can be adjusted using the VOUT pin to set the output amplitude to a lower value if required.
