Hi ROLAN:

I use oscillator as the clock source for CDCE913 instead of crystal,

because i want to get synchrotron signal from two CDCE913, So i want to know

the connection type between oscillator and two CDCE913, Should I use series resistor or couple capacitor ?

and the best value for series resistor or couple capacitor ?

Best Regard!

For the CDCE913 you can connect directly a 1.8VLVCMOS singal as specified in the datasheet when the input type is configured as LVCMOS. You can do that by setting bit 3 and bit 2 of byte 1 to '10'.
