DS90UH929-Q1: The test of SAE J1752-x

Nao

Hi, E2E members

Do you have test data SAE J1752-1, 2, 3 against IC or EVM?
The customer ask it to me. They want to confirm the data for DS90UH929.
If you test it, could you please provide the data?

=====
1) SAE J1752-1：Electromagnetic compatibility measurement procedures for integrated circuits
- integrated circuit EMC measurement procedures, general and definitions - Mar97

(2) SAE J1752-2: Electromagnetic compatibility measurement procedures for integrated circuits
- integrated circuit radiated emissions diagnostic procedure 1MHz to 1000MHz, Magnetic Field
- loop probe - Mar95

(3) SAE J1752-3: Electromagnetic compatibility measurement procedures for integrated circuits
- integrated circuit radiated emissions diagnostic procedure 150kHz to 1000MHz, TEM Cell-Mar95

Hi Nao,
At system level we test radiated emissions to CISPR25-L5 and radiated immunity to ISO 11452-4.
I'll check for chip level tests.

Hi Nao,

I verified that we have not tested to SAE-1752.

For system level EMC testing, we have a report for the DS90Ux949, which is the single-port version of the DS90Ux929.

Hi, Mike

Thank you for your feedback.

1) Do you have a plan to test to SAE-1752?
2) Is the system test about testing with EVM?
3) Can I get the report to CISPR25-L5 and ISO 11452-4?
4) You say that you have the report for the DS90Ux949.
Does result of this report same as DS90Ux929?

Regars,
Nao

DS90UB949A_948A_EMI_062317.pdf DS90UH949-UH948 BCI Testing at 100mA Results Rev 1.3.pdfHi Nao,

1. No, we have no plans to test to this spec.

2. Yes, system level testing is with EVMs.

3. Yes, I have attached them. This includes ISO 7637-3 Conducted Immunity testing which is normally not included. All tests pass.

4. Yes, they have the same transceiver design.
