•
Doubler: Can double input signal frequency (input must be 50% duty cycle to use this)
•
Pre-R divider: Divides frequencies up to 1400 MHz
•
Multiplier: Multiplies frequencies between 40 to 70 MHz and outputs between 180 to 250 MHz
•
R divider: Used for dividing frequencies below 5 MHz for very low PFD
•
Charge Pump Gain: This tab will auto-update both UP and DN to be equal. Go to bits/pins section
if you want to force different values.
•
Gain multiplier: Multiplies Charge Pump Gain by a factor
•
State: Changes the charge pump output state
•
FCAL_EN: Every time you change the output frequency, toggle this off or on to calibrate the device
to the frequency.
•
Fvco: Set the VCO frequency between 3550 to 7100 MHz.
•
Divider MUX: This determines which of the 3 segments is included for a total division between 2 to
192.
•
Output MUX: Selects the signal from the VCO output or the Divider.
•
Power Settings: Changes the output power (increase 0 to 31, then additional boost with 49 to 63).
5. Burst Mode
•
Enter a register in
Load Register
or delay in seconds.
•
You can run and stop the commands in a single burst or continuous loop.
