The maximum clock frequency for the CY7B991V-5JXIT is 200 MHz. However, it's recommended to check the specific application and system requirements to ensure the device operates within its specified parameters.
Cypress provides guidelines for clock domain crossing in their application notes. It's recommended to use a synchronizer or a FIFO to handle CDC, and to ensure that the clock domains are properly isolated to prevent metastability issues.
The recommended termination scheme for the output signals of the CY7B991V-5JXIT is to use a series resistor (Rs) of 22-33 ohms, along with a parallel capacitor (Cp) of 10-20 pF, to match the impedance of the transmission line and prevent signal reflections.
It's recommended to follow the power-up and power-down sequencing guidelines provided in the datasheet, which typically involve powering up the device in a specific order (e.g., VCC, then VCCIO, then clock) and powering down in the reverse order.
The CY7B991V-5JXIT has an operating temperature range of -40°C to +85°C. However, it's recommended to check the specific application and system requirements to ensure the device operates within its specified parameters.
