The recommended power-up sequence is to apply VCC first, followed by VCCIO, and then the input clock signal. This ensures proper device operation and prevents latch-up.
To optimize the clock tree, use a balanced clock tree architecture, minimize clock skew, and ensure that the clock signal is clean and free of noise. Additionally, use a clock buffer or repeater to maintain signal integrity.
The CDCVF2310 supports frequencies up to 230 MHz, but the actual frequency limit depends on the specific application, PCB layout, and clock signal quality.
To handle metastability issues, use synchronous design techniques, ensure proper clock domain crossing, and implement metastability-resistant flip-flops. Additionally, consider using asynchronous FIFOs or synchronizers to mitigate metastability risks.
The recommended termination scheme is to use a series resistor (Rs) of 22-33 ohms and a parallel capacitor (Cp) of 10-22 pF to match the impedance of the transmission line and minimize signal reflections.
