Notes:
1. f(RF) = 1 MHz, f(IF) = 1 MHz, RF1 = 2.4 GHz, RF2 = 2.1 GHz, IFOUT = 800 MHz, LPWR = 0, for all parameters
unless otherwise noted.
2. RF VCO tuning range limits are fixed by inductance of internally bonded wires.
3. From powerup request (PWDN or SEN during a write of 1 to bits PDIB and PDRB in Register 2) to RF and IF
synthesizers ready (settled to within 0.1 ppm frequency error).
4. From powerdown request (PWDN, or SENduring a write of 0 to bits PDIB and PDRB in Register 2) to supply current
equal to IPWDN.
