ADRF6604
LO SELECTION LOGIC
The downconverting mixer in the ADRF6604 can be used without
the internal PLL by applying an external differential LO to Pin 37
(LON) and Pin 38 (LOP). In addition, when using an LO generated
by the internal PLL, the LO signal can be accessed directly at these
same pins. This function can be used for debugging purposes,
or the internally generated LO can be used as the LO for a
separate mixer.

The operation of the LO generation, as well as whether LOP and
LON are inputs or outputs, is determined by the logic levels applied
at Pin 16 (PLL_EN) and Pin 36 (LODRV_EN), as well as Bit DB3
(LDRV) and Bit DB6 (PLEN) in Register 5. The combination of
externally applied logic and internal bits required for particular
LO functions is given in Table 9.
