CY2300SXCT datasheet by Cypress Semiconductor

CY2300SXCT Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CY2300SXCT?
  The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock input. This ensures proper initialization of the device.
• How do I ensure that the CY2300SXCT is in a known state after power-up?
  You can use the POR (Power-On Reset) pin to reset the device after power-up. The POR pin is active low and can be connected to a pull-up resistor and a capacitor to create a power-on reset circuit.
• What is the maximum clock frequency that the CY2300SXCT can support?
  The maximum clock frequency that the CY2300SXCT can support is 133 MHz. However, the actual clock frequency may be limited by the specific application and the quality of the clock signal.
• How do I configure the CY2300SXCT for spread spectrum clocking (SSC) mode?
  To configure the CY2300SXCT for SSC mode, you need to set the SSC_EN pin high and program the SSC frequency and modulation rate using the SSC_FREQ and SSC_MOD registers. Refer to the datasheet for the specific register settings and values.
• What is the purpose of the VREF pin on the CY2300SXCT?
  The VREF pin is used as a reference voltage for the internal PLL (Phase-Locked Loop) circuitry. It should be connected to a stable voltage source, typically VCC/2, to ensure proper PLL operation.
