Hello Team,

What is the best equivalent option we have from TI for MAX9277 and MAX9278.

My customer has Open-LDI input and output and want to use single coax only.

DS90UB947-Q1 and DS90UB948-Q1 is becoming overkill solution for them.

Regards,

Mahendra

Hello Mahendra,

what is the PCLK to be used?
Generally if the PCLK is within 5 - 85MHz then I recommend they use the DS90UB927 and the DS90UB928.

Hello Hamhaz,
PCLK of 85MHz is sufficient. But does 927/928 support operation over a single coax cable? my customer wants to use single coax only. Maximum cable length is 6m.
It is not mentioned in the datasheet?
Regards,
Mahendra

No, Coax is unfortunately not supported. Then only the 947 -948 can do the job.

Hi Mahendra,

Hamzeh is correct, the 92x does not support coax and we do not have any ADAS products, that mainly support coax, that have oLDI input.
