CDCE6214-Q1: Programming for SSC

Carlo Mazzetti
Prodigy 10 points

Part Number: CDCE6214-Q1

Hi,

We are using the CDCE6214-Q1 configured for a default frequency of 100MHz on page 0.

We need to program page 1 for SSC 100MHz, 0.25% down-spreadyng at 32KHz.

then we need the capability to select NVM Page 0 or Page 1 by controlling only the pins of the devices.

Our system as access ot I2C interface and control for each pin.

Could you provide the steps required to do so?

Thanks

    Hi Carlo,

    We're currently investigating your inquiry, I'll get back to you early next week.

    Hi Carlo,

     

    Using I2C to interface with the register mapping of the device, you can control which page of EEPROM to use for NVM commit operations via register R3[9]. By setting this to 1h, making changes, and committing the register contents to EEPROM (R3[10]), you can program SSC settings to page 1. Here is the CDCE6214-Q1 register map for your reference: CDCE6214-Q1 Registers.

     

    The CDCE6214-Q1 also allows you to select EEPROM page 0 or page 1 by controlling the HW_SW_CTRL pin on the device (pin 23). HW_SW_CTRL=0 selects page 0 while HW_SW_CTRL=1 selects page 1.

     

    Best,
