Hi Maharajan P,

Thank you for bringing this to my attention. I will get the product page corrected.

The operating temperature is -40 to 105 deg C.

The 125 deg C refers to the maximum junction temperature allowed. More information is mentioned in this section of the datasheet:

Jennifer

Hi Maharajan P,

In the case you need PTP and SyncE support, then the LMK05318B/LMK5B12204 or LMK5B33216/LMK5B33414/LMK5B12212 are the network synchronizers to use from the TI portfolio. However, they can not exceed 85 deg C for the operating temperature.

Jennifer
