Part Number: LMX2572 Other Parts Discussed in Thread: , LMK61PD0A2 Hello,
I am currently using the LMX2572EVM to evaluate the LMX2572 for a fast frequency switching application in which we would like to hit the 5us VCO lock time for full calibration assist…
Part Number: LMX2572LPEVM Other Parts Discussed in Thread: LMX2572EVM I have to modify PLL bandwidth, i modified R2_LF value. I wondered: R2_LF value wasn't 330 ohm as in User's Guide but 68 ohm. I found the same bug on LMX2572EVM - I have tested it…
Part Number: LMX2572LP Other Parts Discussed in Thread: LMX2572EVM Hello,
I plan to use LMX2572LP at VHF (vide avionic band 118-156MHz), in integer mode, with phase detector frequency 267kHz and 1-st IF 45MHz, then highest 1-st LO frequency multiplied…
Looking at the schematic of the USB2ANY and the LMX2572EVM board, it looks like there is an unused 3.3V supply pin from the USB2ANY and the LMX2572EVM , and also the Ramp_Dir and Ramp_Clock pins.
Why could not the USB2ANY power the LMX2572EVM board?
Are…
Other Parts Discussed in Thread: LMX2572EVM Hello,
I own a LMX2572EVM board (evaluation module) with the Reference PRO board. The hardware setup is identical to the one proposed in the LMX2572EVM Evaluation Module document.
To control the system, I use…
Hi Narendra,
Were you able to reproduce the example ramp as shown in datasheet 7.3.14.2.1?
Suggest also to read the LMX2572 datasheet section 8.1.7.2 for additional frequency ramp details. The LMX2572EVM user's guide section 3.2.3 has another ramp example…
Part Number: USB2ANY I have built a windows application including the TI HID library and would like to use it to control the LMX2572EVM board using USB via the Reference PRO board. Therefore I'd like to know the commands that can be sent/received using…
Part Number: TICSPRO-SW Other Parts Discussed in Thread: LMX2572EVM Hi Team,
A customer bought LMX2572EVM and tried to download the TICSPRO-SW software but can't access the download site after clicking the "Request" button. We also tried thru other computers…
Hi ACGUY,
By default, Tics Pro has all the features disabled and is setup for simple synthesizer operation. If you need FSK, setup your FSK in the FSK section in User Controls page. Follow the instruction in User's guide, you should be able to generate…
Hello,
Yes, triggering on the OSCin channel is critical. As the phase shift is with respect to the OSCin channel. Depending on the frequency, matching the cable lengths to the oscilloscope will also be important. You will not see the phase shift without…
