Specifications subject to change without notice.
REV. A
Standard operating mode: LNA/Mixer @ high bias setting, VGA @ Min ATTEN setting, synthesizers in normal (not fast acquire) mode, f
factor = 900, 16-bit digital output, and 10 pF load on SSI output pins.
This includes 0.9 dB loss of matching network.
AGC with DVGA enabled.
Measured in 10 kHz bandwidth.
Programmable in 0.67 mA steps.
Voltage span in which LO (or CLK) charge pump output current is maintained within 5% of nominal value of VDDP/2 (or VDDQ/2).
VDDH must be less than VDDD + 0.5 V.
Clock VCO off, add additional 0.7 mA with VGA @ Max ATTEN setting.
