Changes
#1 Changed DDR4 SDRAM (U2, U3, U9, U12) from K4A8G165WB-BIRC to K4A8G165WC-BITDTCV. Set resistor (R68) to not fitted.
...
Impact: New programming file is necessary. Trenz reference design consideres new PLL programming information but custom programming files needs need to be updated by customer. For more information take a look at AN1006-Si534x-8x-RevB-RevD-Differences.
...
Impact:Improved VTT voltage rail reliabililty.
#11

package size.
Type: PCB Change
Reason: Increase DDR4 usage flexibility.
Impact: None. More DDR4 Chips are usableLarger packages can be assembled.
#12 Enabled DDR4 test usage via connecting DDR4-TEN signals together for DDR4 memory (U2, U3, U9, U12) and pulling them down via 499 Ohm resistor (R103). Added testpoint (TP3) for signal DDR4-TEN.
...
Type: Schematic Change
Reason: Remote Add remote sense option.
Impact: None.
...
Type: Schematic Change
Reason: Enable POR Override Add option to enable POR_OVERRIDE feature.
Impact: None.
#17 Changed 10 nF capacitor (C112) from 16 V, 0402 to 10 V, 0201.
