Data Sheet

ADF5355

Another feature of the ADF5355 is that the supply current to

the RFOUTA+/RFOUTA− output stage can shut down until the

ADF5355 achieves lock as measured by the digital lock detect

circuitry. The mute till lock detect (MTLD) bit (Bit DB11) in

RFOUTB directly connects to the VCO, and it can be muted but

only by using the RFOUTB bit (Bit DB10) in Register 6.

Table 6. Total IDD (RFOUTA± Refers to RFOUTA+/RFOUTA−)

Divide By

RFOUTA± Off

RFOUTA± = −4 dBm

RFOUTA± = −1 dBm

RFOUTA± = +2 dBm

RFOUTA± = +5 dBm
