ADRF6620 MUXOUT output level

Question

Hello, 
 I would like to confirm ADRF6620 MUXOUT pin's output level. 
 The pin is configured by register REF_MUX_SEL(0x21). 
 Question 
 1, If the MUXOUT is selected "LOCK_DET" or "VPTAT", is the MUXOUT pin voltage same as 3.3V logic level? 
 2, If the MUXOUT is selected "REFCLK/x", is the MUXOUT pin same as REFIN input level? 
 Thanks and best regards, 
 Jun

Hello Jun, 
 
 When configured to output Ref clock, the Muxout has CMOS levels. The Muxout is mainly designed for debugging purposes with very little driving capability, therefore I would not recommend using in any other way. 
 
 Hope this answers your question.
