Figure 232. External LO Series Equivalent Differential Input Impedance
Care should be taken when selecting an on-board balun for this application. Combination of amplitude and phase balance performance
of the balun can affect quadrature error performance. Additionally, duty cycle and differential second order harmonic distortion impacts
the ability of to correct quadrature error. The recommended minimum requirement for Ext LO input pins is a combination of no more
than 5 degree differential phase error, 1dB differential amplitude error, 2% duty cycle error, and less than −50 dBc even order
harmonics(primarily 2nd order).
The ADRV9001 provides special mode of operation for external LO in range from 500 MHz to 1000 MHz. In that region it is possible to
inject external LO that will produce RF Channel frequency with x1 multiplier.
For example:
For FEXTLO = 500 MHz the FCHANNEL = 500 MHz
For FEXTLO = 1000 MHz, the FCHANNEL = 1000 MHz
