      Is the si5341b-b05071-gm chip used on ZCU102 a custom chip purchased from Silicon Labs by XILINX? Does this chip require programming?

Thank you @thakurr

 SI5341BB05071-GM is The Custom Factory Preprogrammed Devices.The frequency of the output is what we want, we can just replace it without programming.

Thanks

Hi @jialf521

Yes, Si5341b is is a one-time programmable clock source. This is configured using ClockBuilderPro software from Silicon labs.

Thank you for your answer @thakurr

    According to the manual, the chip with the XXXX number is already a new film customized by the factory. Does this mean that the chip has met some output clock? If this chip needs to be reprogrammed, the corresponding register configuration file is not found on XILINX official website.

Thanks

Hi @jialf521

Thanks for the pointers. As already mentioned there Si5340 B comes as either base devices (Programmed through SPI interface) or factory programmed devices (programmed Clock builder Pro software). Since this device is one time programmable (which has been mentioned in UG1182, page 44), if you need any additional feature or setting which is not there in CB pro software then you can request to Silicon lab before pre-programming:

You can further contact Silicon labs support to get a confirmation on the re-programming thing (i am just telling you what has been mentioned in our UG)
