The maximum clock frequency for the CY7B991-7JXCT is 200 MHz. However, it's recommended to check the specific application and system requirements to ensure the device operates within its specified frequency range.
Cypress provides guidelines for clock domain crossing in their application notes. In general, it's recommended to use synchronization circuits, such as FIFOs or synchronizers, to ensure data integrity when crossing clock domains.
The recommended termination scheme for the output signals of the CY7B991-7JXCT is to use a 50-ohm resistor in series with the output pin, followed by a 50-ohm load to VCC or GND. This helps to reduce signal reflections and improve signal integrity.
Metastability issues can occur when asynchronous signals are used. To handle metastability, Cypress recommends using synchronization circuits, such as synchronizers or FIFOs, to ensure data integrity. Additionally, it's recommended to use asynchronous signal detection and correction mechanisms.
The power consumption of the CY7B991-7JXCT depends on the operating frequency, voltage, and other factors. According to the datasheet, the typical power consumption is around 1.5W at 200 MHz and 3.3V. However, it's recommended to check the specific application and system requirements to ensure accurate power consumption estimates.
