Part Number: CDCE913
I use the CDCE913 and use the clockPro to generate the register setting like blow:
Input frequence : LVCMOS 30.72MHz
Output frequence : LVCMOS 24.576MHz
and generate the setting file is like:
Bit ==> 76543210Byte 00 - 00000001Byte 01 - 00001000Byte 02 - 10110100Byte 03 - 00001001Byte 04 - 00000010Byte 05 - 01010000Byte 06 - 01000000Byte 07 - 00000000Byte 08 - 00000000Byte 09 - 00000000Byte 10 - 00000000Byte 11 - 00000000Byte 12 - 00000000Byte 13 - 00000000Byte 14 - 00000000Byte 15 - 00000000Byte 16 - 00000000Byte 17 - 00000000Byte 18 - 00000000Byte 19 - 00000000Byte 20 - 01101101Byte 21 - 00000010Byte 22 - 00000000Byte 23 - 00000000Byte 24 - 11100101Byte 25 - 10001100Byte 26 - 11000011Byte 27 - 10001011Byte 28 - 11100101Byte 29 - 10001100Byte 30 - 11000011Byte 31 - 10001011
And on PCB, I connect the S0 to 1.8V ,but I can not got the output?
Could you help me about this problem.
Your configuration looks correct. I would check that the voltage swing of the input clock you are providing meets the input requirements in the Recommended Operating Conditions table of the datasheet:

In reply to Tim Chao Li:
Thank you for your reply!
The voltage I think meets the requirements.
Below do not care about the frequence ,just see the voltage .
Any other problem I have ?
In reply to FEI WANG:
Can you provide the .isf configuration file that you used to program your device? (You may need to put it in a .zip folder to upload it to E2E).
This is the ISF file .
The .isf file you have seems fine. I'm not sure what the issue could be.
Are you testing this on an EVM or are you programming a loose part?
If you are testing on an EVM, I noticed that in your screenshot, the connection light is off, which means there is no communication with the EVM. When ClockPro asks to select a device, be sure to select 'CDCE913', not '(Local) CDCE913)', since that sets the program to Demo Mode where it does not connect to the EVM.
If you are programming a loose device using the programmer EVM, I would verify that the EEPROM is programmed correctly by pressing the 'EEPROM=' button to double check that the EEPROM is identical to the config file contents.
Thank you for your reply!
I use the CDCE9XXPROGRMEVM for programming and then put the chip on my PCB .
Yes, I use 'EEPROM = ' to verify the chip after program it.
The setting for 'CDCE913' I can not find this .
So do I need some more setting ?
Right now ,I got the checksum fails from EVM,what should I do ?
It is mean I did not save the setting into the EEPROM ,right?
