CDCE62002: SPI access timing

Masazumi Ishii

Part Number: CDCE62002

Hello.

I have a question about CDCE62002.

Regardless of the presence or absence of REF_CLK, we are planning to do SPI access immediately after Start - Up Time dependencies (Power up) in Datasheet: Figure 27.
For SPI access, we are thinking about setting Buffer select and Loop filter.

Is there no problem?

Thank you.

Hello Ishii-san,

Do I understand you are powering up device from EEPROM, then what to change the loop filter from EEPROM value?
Can you elaborate more about buffer select?

Hello.

Thank you for answering.

We will not use EEPROM.
Therefore, it does not write to EEPROM.

We will all write to RAM.

Therefore, we think that we will change the setting every time at startup from the initial value of the device.

Thank you.

Hello Ishii-san,

There is no problem to power up the device then write all the registers.
