Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-speed PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using impedance-controlled traces.
Metastability issues can occur due to the asynchronous nature of the ADC output. To handle this, use a synchronizer circuit or a metastable-resistant flip-flop to resynchronize the output data with the system clock.
The maximum clock frequency is 105 MSPS, but it's recommended to derate the clock frequency based on the system's noise and jitter budget to ensure optimal performance.
The ADC14C105CISQ/NOPB has an internal calibration circuit that can be used to calibrate the ADC. Refer to the datasheet for the calibration procedure, and consider using an external calibration signal if required.
The power consumption of the ADC varies depending on the operating mode. Refer to the datasheet for the power consumption specifications, and consider using power-down modes to reduce power consumption when not in use.
