Part Number: LMX2572LP I would like to confirm the input level of OSCin (Single-ended input buffer) of LMX2572LP. In the catalog, the OSCin input voltage is listed as min: 0.3 to max: 3.6V. Is it safe to assume that this value is Vp-p from Figure 154? And…
Hi Noel,
The characteristics were verified with the LMX2572LP evaluation board. As a result, it was confirmed that the phase noise was almost the same as that of the simulation. We also confirmed good results for spurious. Thank you very much for your support…
Part Number: LMX2572LP We are planning to use LMX2572LP as local oscillator in our radio. The required frequency is from 110MHz to 300MHZ and it should able to tune in 1Hz resolution as per radio operating frequency. Whether this device meets the frequency…
Hi Vicente,
Also in other thread, Case that VCO core4 has higher spurs are reported.
It is seems that if we use SPI fast mode, spurs will be improved.
But, is there any way to use I2S mode with low spurs?

Part Number: LMX2572LP Other Parts Discussed in Thread: LMX2592 , Hello! We use SPI bus to control and configure devices in system, all devices connect to SPI bus are daisy-chain topology. There are two LMX2592 chips ,one LMX2572LP chips and other 5 devices…
Part Number: LMX2572LP Hi,
Our customer is using the LMX2572LP's FSK I2S mode for FM modulation, but only when using VCO core 4 are the spurs getting louder around the carrier. The desired modulation frequency &Diviation is set with the settings below…
Part Number: LMX2572LP With the LMX2572LP, is there any way to put the pin into the MUXout pin 20 into a High Impedance state?
The MUXout pin can be set between lock detect and register readback. In register readback, it behaves like SPI SDO. In order…
Part Number: LMX2572LP Hello,
To replace IDT 5V9885 by LMX2572LP, we are running some case of simulations on TICS pro.
Target EE is video system, it is required 74.25MHz and 74.25/1.001=74.175824175824200MHz output to cover TV monitor filed clock and…
Part Number: AFE7071 Other Parts Discussed in Thread: LMX2572LP , AFE7070 , LMX2572 In some of your app notes, TI recommends using the LMX2572LP to generate the LO input to the AFE7070/AFE7071. The output from the LMX2572LP is more or less a square wave…
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…
