Question asked by Maria Employee on Apr 5, 2018

Hope you are doing well! Can you please help me with the below queries on the part ADF5356BCPZ:

 

  • Expected voltage on CPOUT pin
  • Expected voltage on VBIAS pin

 

 

  • Any sequencing to be followed between the 5v and 3.3v power supplies ?

 

  • Can you please help to populate the missing Power draw nos. (marked with “?”) across the different supplies ?

 

 

Power supply pin

Max Current draw at no load(ma)

VP

9ma (is this same as CPOUT)

VVCO

90ma

AVDD

?

DVDD

?

VRF

56ma considering 5dbm setting ? is this correct

CPOUT

9ma Same as VP ?

AVDD * DVDD together supply 92ma , can I get the individual current split across these 2 supplies ?

 

  • It appears that the CPOUT pin has a fixed resistor of 5.1k internally ? so is there no external resistance required ?

 

 

 

 

  • Are the RFinputs ECL type?

 

  • Output stage tail current draw as highlighted below?
