Part Number: LMX2572 Tool/software: I'm looking for a simple way to implement an LMX2572 chip into my design without spending a month writing software and tweaking my PCB for VSWR.
Part Number: LMX2572 Tool/software: The VCO output is ok with good phase noise and output power over the full range of 3.2GHz to 6.4GHz. But the channel divider outputs have very bad spectrum and power as if the dividers are not being driven hard enough…
Part Number: LMX2572 Other Parts Discussed in Thread: LMX2594 , LMX2595 Tool/software: The synthesizer chip behaves normally with good spectrum and phase noise but when using the divider the spectrum is very poor and broad. However, when I use a foam tipped…
Hi BZ,
You need to do a VCO calibration and a register read back to find out the exact VCO parameters ( VCO_SEL; VCO_CAPCTRL and VCO_DACISET) for the frequency you want. When you apply the data, you have to put the device in full assist mode. Looks like…
Part Number: LMX2572 Can I get any sample code or libraries that can be implemented for programming this PLL?
set frequency ,RAMP.... It can be for any embedded platform even Linux. advanced thanks. BZ
Part Number: LMX2572 Hi!
I am using the LMX2572 and wanted to ask a clarification question concerning the VCO's output.
On the data sheet in section 8.1.5.3 Unused Output Pin, they mentioned that the buffer can be used as two single-ended outputs…
Part Number: LMX2572 Tool/software: Hi Team,
There is an issue in Reference Path while using LMX2572.
OSCin=125MHz and the required phase detector frequency is 83.33 MHz. 83.33MHz=125MHz×2÷3.
If doubler in Reference Path is used, the frequency…
Hi Abishek, 1. What do you have connected to the RampClk pin? If there is a rising edge at this pin - this will trigger the ramping.
2. To begin with, a 1.1 - 1.6 GHz RFout requires the outputMUX to be set to "channel divider:" When you did the sweep from…
Part Number: LMX2572 Hi,
1) maximum spi clk frequency mentioned in LMX2572 datasheet is 75Mhz. My code is working fine till 3Mhz, but after that I am not able to get output .
2)Also I want to generate ramp from 2400Mhz to 2500Mhz within 400 microseconds…
