ADRF6755 LOMON output

Hi,all

 

About the "controls the LO monitor outputs" and the "LO output circuits" at the ADRF6755,

in the datasheet 37 page @ ADRF6755,

" If not used, these outputs should be tied to REGOUT."

and 29 page,

"Register CR27, Bit 2. Controls the LO monitor outputs, LOMON and /LOMON.

The default is 0 when the monitor outputs are powered down. "

 

Q1

If it does not used LO monitor outputs, only setting the power down bit 0 is imperfect ?

and need to be tied to REGOUT ?

Monitor power down is open-collector outputs?

 

Q2

If controlled the LO monitor outputs on/off, it is necessary the all parts in the recommended circuits ?

In the datasheet 39 page @ ADRF6755, LOMON to +3N_INT, L1, L3/R60, R44.

 

Q3

LOMON single-end output is available?

 

 

Best Regards,

sss
