Dear Sir/Ms.
My customer designed DP83848YB Ethernet phyter,
Because the TEST MODE of the MCU is not available at the time of the test. I want to reserve a probe point, and after SMT, I can test to confirm whether the DP8348 CHIP works. The customer wants to use the test point test directly after the SMT PCB has not been installed in the case.
Which pin should I keep?
The customer though seems to leave TX_CLK or TX_EN.
But TX_CLK speed is too fast.
It looks like TX_EN.
Am I right, right?
After looking at the specifications, PFBOUT should be available.
But the datasheet does not write what the PFBOUT voltage is. Can you tell us PFBOUT pin voltage?
Can you tell us if you want to place test points, can you pull out those PINs?
Best Regards,
Kami Huang
