Hi KK,
Below refers to High-end version.
When I'm checking the component from my package against the Schematic, component list and the PCB, I found following discrepnacies:
PCB DAC:
. The IC provided is CS8414, but the R1 and C3 provided is 1K & 0.047u respectively, not the one highlighted in your powerpoint: CS8418 match with 470 and 0.068u
. The C11 value from my package is 0.6h (measured via a multimeter), not 470p as stated on the schematic.
PCB IV2:
. R6 & R8 under Schematic is 10K, the value measured from my package is 20K
. C3 & C4 under Schematic is 220u, the value measured from my package and the component list stated is 47u.
PCB Power:
. From the Schematic and PCB, there is a L1 mentioned, I found no L1 from my package.
PCB REV(R101)
. R2 - R5 under Schematic and the component list is 470, the value measured from my package is 270.
. I found no C3 1000uF from my package
Please advise, thanks. |
