• ADF4372 / ADF4371 initialization

    Hi ADI

    I'm want to setup my ADF4372, however some of the the datasheet descriptions of the various registers are a bit obtuse and it's not obvious how I should set them up. I have an ADF4371 eval board which I can set up to my wanted frequency using your…

  • ADF4372 LEV_SEL not responding

    Hi ADI

    We're using your ADF4372 and can't seem to get the LEV_SEL bit to respond. The SDIO and MUXOUT pins only seem to give out 1.5V for a logic high not matter what the setting of the LEV_SEL bit?  Please can you help? We seem to be able to talk…

  • ADF4372 3.3V Operation

    I have two questions:

    1. What voltage is VCC_REG_OUT?

    2. What changes to the circuit need to be made to change from VCC_VCO=5V to VCC_VCO=3.3V operation?

    Thanks,

    Michael

  • Can the ADF4372 tolerate a sweeping reference clock?

    Hello, I am using the ADF4372 and intended to having a sweeping reference clock which would get 1000x multiplied in the chip. So far, I can successfully pipe out the low ends and upper ends of the sweep, but only if I rewrite the registers after sweeping…

  • ADF4372 SCLK Falling Edge to Data Out (Muxout) Valid Delay (Taccess)

    Hi, 

    The ADF4372 datasheet (https://www.analog.com/media/en/technical-documentation/data-sheets/adf4372.pdf) specifies a SCLK Falling Edge to SDIO Valid Propagation Delay, Taccess, of 10ns. This number is listed in the "Min' column and there are no other…

  • How to config ADF4372 PLL in divider feedback path?

    I have a design , the ref clock and PFD is 12.5Mhz input,  i need PLL output is 100Mhz, and the output 100Mhz

    must has the same phase relationship with the ref clock(12.5Mhz) every time when power up,  so i select ADF4372

    and use vco divider feedback paht…

  • ADF4372 differential-ended output to signal-ended output

  • ADF4372- Clock Generation in Fractional Mode

    Hello ADI Team,

    I am using ADF4372 PLL for generating Output Clock with frequency 12451.84 MHz in Doubler path (RF16).

    Reference input frequency is 409.6 MHz

    PFD Frequency is 102.4MHz

    Hence N divider value is 60.8.

    What will be value for INT, FRAC1, MOD2…
