CDCE62002: CDCE62002 AUX_IN

Eric Shen42

Part Number: CDCE62002

Dear TI Team：
Does the AUX_IN of CDCE62002 has amplitude requirement?

The amplitude of crystal oscillator from different manufacturers is different, my customer want to check the amplitude requirement.

Thanks!

Regards!

Hi Eric,

Crystal input ESR is specified as 50Ω, and drive level is (for some reason) located in datasheet timing characteristics and specified as 0.1mW (-10dBm) minimum. So RMS volts drive level should be higher than 70.7mV minimum.
