CY7B923-400JC datasheet by Cypress Semiconductor

CY7B923-400JC Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with this device?
  The maximum clock frequency for the CY7B923-400JC is 400 MHz, as indicated by the '400' in the part number. However, the actual clock frequency used may be limited by the specific application and system design.
• How do I implement a clock delay or skew adjustment with this device?
  The CY7B923-400JC has a built-in clock delay feature that allows for up to 3.2 ns of delay adjustment. This can be achieved by using the Clock Delay Select (CDS) pins to select one of eight possible delay settings.
• What is the maximum input clock jitter tolerance for this device?
  The CY7B923-400JC can tolerate up to 1.5 ps of input clock jitter. However, it's recommended to consult the datasheet and application notes for specific guidance on clock jitter tolerance and mitigation techniques.
• Can I use this device as a clock buffer or repeater?
  Yes, the CY7B923-400JC can be used as a clock buffer or repeater to fan out a clock signal to multiple devices or to extend the distance of a clock signal over a backplane or cable.
• How do I ensure that the device is properly powered and bypassed?
  It's essential to follow the power-up and power-down sequencing guidelines outlined in the datasheet to ensure proper device operation. Additionally, Cypress recommends using a 0.1 μF bypass capacitor between the VCC and GND pins to filter out noise and ensure stable operation.
