We have found some problem with FPGA MPN# EP4CGX30CF23I7N PCBA Serial : FBNRK00219060130 Found low resistance between pin F7 vs B2 = 174.2 Ohm

Verification steps:-

1. Component level found only resistance lower than known good unit.

2. FPGA fail on module level with symptom OSC loopback fail, during circuit pack test, the optical service channel loss of frame error was raised. The FPGA (U42) is the OSC FPGA on the circuit board.

3. There is a loss of frame alarm happen when running system test which the module which use these FPGAs. This kind of alarm related to the signal from OSC FPGA

 

So , we would like to send two sample of d/c 1831 to INTEL for further investigation.

 

We are also atttached with the compete ALTERA/INTEL FAR form for your reference

Hi,

 

This is Intel support agent.

 

Typical FA support process in Intel forum is via private message to protect customer design confidentiality.

 

I will initiate the private message discussion with you shortly.

 

Thanks.
