New DDR routing rules:
------------------------------
All timing is relative the CLK/CLKb that arrive at the destination DDR SDRAM chip.
1) X = CLK/CLKb should be a matched differential pair with a length < 4"
2) Address and control should be X +/- 0.75" (or 100 ps)
3) DQS and DQM should be X +/- 0.75" (or 100 ps)
4) All DQs should match corresponding byte lane DQS/DQMs /- 0.20" (or 30 ps)
5) Place 22 ohm resistors for DQ and DQS bidirectional lines half-way between BCM and Memory.
6) Place 22 ohm resistors for CLK, ADDR, BA, DM, RAS, CAS, WE, CKE output-only lines near BCM.
7) Place DDR_VREF[2:1] resistor dividers near BCM.
8) Trace impedances should be 60 to 65 ohms
9) Route DDR_VREF[2:1] with 30-mil trace and at least 1 high quality ceramic bypass capacitor for each
connection to a device.
10) All traces should have a >= 3 to 1 spacing ratio from the reference GND/PWR layer. (e.g. 15 mil
line-to-line spacing for a 5 mil dielectric thickness)
Route clocks as differential pairs
Place Cap Close
to Memory VREF
Place all these TPs near BCM3560,
inside socket border.
Place Cap Close
to Memory VREF
Try to place decoupling capacitors on the
same side of the PCB as the DDR to reduce
the inductance caused by using vias.
