C; limits called out at 0
°
C are guaranteed by design and charac-
terization and are not production tested.
Note 2:
GCI gain control is guaranteed over this voltage range. 0.75V corresponds to maximum gain and 2.6V corresponds to
minimum gain.
Note 3:
RF front-end specification met at this output level.
Note 4:
The VTUNE ADC transfer curve has been tailored to that of the VCO tuning curve.
