The maximum clock frequency for CY7B9945V-2AXC is 200 MHz. However, it's recommended to check the specific application and system requirements to ensure the clock frequency meets the design needs.
Cypress provides a Clock Domain Crossing (CDC) application note (AN54444) that provides guidelines and examples for implementing CDC with CY7B9945V-2AXC. It's recommended to follow the guidelines and use the provided IP cores to ensure proper CDC implementation.
The recommended termination scheme for CY7B9945V-2AXC is to use a 50-ohm termination resistor on the output pins and a 100-ohm differential termination resistor on the input pins. However, the specific termination scheme may vary depending on the system requirements and PCB layout.
Metastability issues can be handled by using synchronizers, such as the Cypress-provided synchronizer IP core, to resynchronize the data signals. Additionally, it's recommended to follow the guidelines provided in the Cypress application note (AN54444) for metastability handling.
The power consumption of CY7B9945V-2AXC varies depending on the operating frequency, voltage, and system requirements. According to the datasheet, the typical power consumption is around 1.2W at 200 MHz and 1.8V. However, it's recommended to check the specific application and system requirements to estimate the power consumption accurately.
