Hello all,

We used CDCE62005 in our old design and we used to order them programmed with our configurations...Now we are designing a new board with CDCM6208 and just realized that this part doesn't have ab internal EEPROM as the CDCE62005 did...but also the data sheet says that is comes with default settings...my question is: Can we order the CDCM6208 with our configurations?...or it must be programmed/configured after power up?...PIN configuration doesn't work for us since our output clocks are not part of them.

Regards,

Murad

Hi Murad,

CDCM6208 features non-volatile memory in the form of ROM (no EEPROM on this device). Depending on the volumes of the product driving the end application (business case), ROM configurations can be altered via metal to meet the requirements. We have spun several ROM flavors of CDCM6208 in the recent past and there might be a slim chance that the configuration that you are looking for may be already available in one of these ROM settings. Can you send me your I/O (frequency/format) requirements?

Another good option to consider depending on your frequency plan is LMK03328/LMK03318. These are high performance clock generators with integrated EEPROM (100 times in-system programmable). LMK03318 has a single Fractional-N PLL while LMK03328 features two high performance Fractional-N PLLs.

Last option is CDCE6214 (unreleased - RTM 3Q,2017) that supports multiple frequency domains but we are sampling test silicon to limited customers.

Thank you Sridhar,
We are going to provide SPI interface to the FPGA and program them at power up.
