Looking at the Altium project file provided for TIDA-01570, the stackup has RO4835 LowPro between layer 1/2. I'm fairly sure now that the documentation referring to 370HR was simply incorrect, and that the antenna was designed for RO4835 LowPro.

I designed a board using the AWR1642 chip based on the TIDA-01570 automotive reference design. In mmWave demo when I upload the "profile_2d_srr.cfg" configuration in the…
Check out TIDA-01570 and the associated documentation and software available with it. We have software for object data output from CAN. That design also has a high density connector for raw data output. TIDA-020011 heavily used this design as…
Part Number: AWR1642 Other Parts Discussed in Thread: TIDA-01570 Hello Champion, My customer is refering the schematics in TIDA-01570 which use power solution LM536253Q + LP87702D + TPS7A5201Q + AWR1642. Do we test the overshoot current on 12V input when…
If you look at the TIDA 01570 design ( www.ti.com/.../TIDA-01570) the LP8770 PMIC monitors all the voltages and the GPIO and PG signals of the 8770 are used to control the nRST to the AWR device. This is one option.
Hello Hitoshi San,
For a proper standalone sensor implementation , if you want the PMIC to control the nRST then all the voltages (1.2, 1.8 and 3.3v) need to be monitored before the nRST is released. The LP87524 does not have this capability.
You can find recommended PMIC for AWR1642 in this app-note
LP87524BRNFRQ1 as default PMIC on EVM.
LP87524JRNFRQ1 as Low-cost LC filter solution.
Another PMIC LP87702-Q1 which is being used as a reference in TIDA-01570
Part Number: AWR1642 Other Parts Discussed in Thread: TIDA-01570 Hi
I have a question about the document TIDA-01570 ,do the EVM's antennas surface use immersion gold process?
And how much is the thickness of the immersion gold?
Best Regards ,
Our IWR1443 EVM does not actually follow the specified 3ms delay after all of the power rails before NRESET goes high. It is recommend to manually press the NRESET button after power up the EVM.
Ideally, in your own implementation you would…
