Hi
In current AWR2243 reference design(EVB), TI use LP87524, and use LC filter in design.
If we use LP877451 which current used in AWR294x, if there any problem?
What is the performance between LP877451 and lP87524?

Hello,
Are you looking at powering only the AWR2243 device with LP877451 ? That should not be an issue.
For performance difference between LP877451 and LP87524 you can look at their respective datasheets.

LP877451 work @17.4MHz, while LP87524 work @2MHz, there is LC filter in LP87524, even we use LC filter, the harmonic would interence AWR2243. but If we use LP877451, then without this issue. am I right?
Hello Wang,
If you plan to use <15Mhz IF bandwidth on AWR2243 then the 17.4Mhz spur would be out of band and not cause an issue. Hence you can eliminate the LC filter.
