Hi,
I'm trying to test the JESD204B SerDes of ADC34J45 using the test pattern feature.
I set register 0x06 with 0x02, and tried several option according to data sheet:
0x0A,0x0B | Datasheet | Measured |
0x11 | All 0's | OK |
0x22 | All 1's | OK |
0x33 | Toggle | OK |
0x44 | Digital Ramp | Not OK, got counter from bit 1 not from bit 0 |
0x66 | Deskew Pattern 0x3AAAA | Not OK, Got 0x2AAAA |
is this means that I have SerDes timing issues or that the ADC test pattern works like this.
Best Regards,
Ran
