Notes On Handling
Be sure not to separate the analog and digital power supplies, and the analog and digital GND.
The ground pattern should be as wide as possible. Using a multi-layer substrate with a mat ground is recommended.
Ground the power supply pins of the IC with a 0.1
F or larger ceramic chip capacitor as close to each pin as possible.
Be sure to accurately match the I/O characteristic impedance in order to ensure sufficient performance
during high-speed operation.
Design the set so that the loop filter (external) is located at the minimum distance. (See the CXA3266Q PWB.)
The voltage applied to VOCLP pin must be supplied from the stabilized power supplies (3-pin regulator etc.)
because of the construction of internal circuit.
