Question on oscillator

Other Parts Discussed in Thread: TVP5146M2

Hi All,

 

I would like to ask a question on oscillator.

 

 

 

 

In schematics for EVM6437, between J19 and K19 of DM6437 there is a NO-POP resistor; while between XTAL1 and XTAL2 of TVP5146M2 there is a 100K resistor.

 

What is the purpose of these resistors? How will they affect the system?

 

 

 

 

 

Thanks,

Zheng
