LMK05318: LMK05318 roadmap question

Part Number: LMK05318
Other Parts Discussed in Thread: , LMK5B33216

Tool/software:

Hi team, 

do we have lower cost device like LMK05318 to support below request? The LMK05318 can fit these request well but they think the cost is a little bit high.

1. need the input clock and TCXO as reference sources at the same time, for example, we can have two outputs at the same time, one is locked to the input reference clock, and the other is locked to the TCXO input clock. Can both chips achieve this function?

2. support IEEE 1588 and SyncE PLL
