Hi Maharajan ,

We currently do not support such operating temperature range in the network synchronizer (DPLL) product family.

Can you please specify which application requires the operating temperature range of -55 degC to 125 degC?

Regards,

Jennifer

Hi Maharajan ,

We have space or HiRel grade devices that support -55 degC to 125 degC. Can you please specify the frequency plan as well as the output phase noise/jitter requirements?

The full list can be found in the ti.com Clocking portfolio when sorting by temperature.

HIi Jennifer,

Is there any availability of extending the temperature range of LMK5B12212 part to military(-55 to +125) temperature range.

Thanks and regards,

Hi Maharajan,

We do not have plans to extended the temperature range to the military application at this time. That would require a package change and another round of validation testing which we do not foresee doing in the nearby future.

If you specify your frequency plan requirements, I can see if another clocking device with military grade can meet your needs.

Jennifer

Hi Maharajan ,

Please also specify the output jitter/phase noise requirement for each output clock so that I can make sure the recommended device can meet your needs.

Jennifer

Hii Jennifer,

It would be better if available as same as LMK5B12212, if not also is fine, as long as frequency can be configured as Same mentioned in above table.

Thanks and regards

Hi Maharajan,

The LMK04832-SEP is a jitter cleaner for military applications.

Is there flexibility in changing the 266.x MHz frequency? All outputs except 27 MHz and 266.x MHz can come from one VCO frequency (2500 MHz).
1. With the 266.x MHz frequency included means that there are two frequency domains and two VCOs are required to generate the frequency plan.
2. If the 266.x MHz can be modified to a frequency divisible by 2500 MHz, this can be a one chip solution with the LMK04832-SEP. The 27 MHz can be sourced from the OSCout pin with a CLKin input of 27 MHz.
If there is no flexibility, then a two chip solution using LMK04832-SEP is required to meet the frequency plan and military grade requirement.

Please let me know your thoughts on the above proposal.

Regards,

Jennifer
