Hi,
I'm a DFAE in Japan. The customer is thinking of adopting ADF4154 or ADF4156, but he wants to use the input frequency at 78MHz. In this case, is it possible to operate at the low frequency if the slew rate is kept at 400V / µs?
Regards,

My customer purchased some ADF4154 PLLs a while ago and performed exactly like the simulation. Then they purchased a few more and
all parts have higher phase noise on in-loop band and it seems the figure of merit of the new batch is much higher…
Hello,
My customer is asking if ADI can make the firmware available for the Cypress PSOC (CY7C68013) microcontroller that does the conversion from USB to serial that is on the ADF4154 PC interface board (parat number EVAL-SDP-CS1Z)?
Thank you,

Hi,
I have a current prototype design with a ADF4154, the ability to achieve quick settling (<20us) using the fast-lock feature is critical, for production I would like to add a lock detect indication and so am considering a replacement part.

Is there a loop filter on your board? Are R1, R2, C1, C2 and C3 populated?

Hi Tim,
You're correct, It should be in the "speedup mode" drop down menu on the left of the screen and it's not there for either the ADF4154 or ADF4157 -- checked both.

Hello
We are using a ADF4154BRUZ created a PLL.
However, too much bad has occurred in the low-temperature test -32'C.
Researching the part # 220 and # 421 were marked as a normal product,
Defective products were marked with # 539.
X-RAY measurements…
ADI PLLs are typically programmed using a three-wire serial interface, where the serial programming data is clocked into an internal shift register and is then latched onto the internal data bus on a rising edge of latch enable (see SPI Programming section…
