7.2.2.6 PCB Stackup

The minimum stackup for routing the DDR3 interface is a six-layer stack up as shown in Table 7-6. Additional layers may be added to the PCB stackup to accommodate other circuitry, enhance SI/EMI performance, or to reduce the size of the PCB footprint. Complete stackup specifications are provided in Table 7-7.

Table 7-6 Six-Layer PCB Stackup Suggestion

LAYER TYPE DESCRIPTION
1 Signal Top routing mostly vertical
2 Plane Ground
3 Plane Split power plane
4 Plane Split power plane or Internal routing
5 Plane Ground
6 Signal Bottom routing mostly horizontal

Table 7-7 PCB Stackup Specifications

NO. PARAMETER MIN TYP MAX UNIT
PS1 PCB routing/plane layers 6
PS2 Signal routing layers 3
PS3 Full ground reference layers under DDR3 routing region(1) 1
PS4 Full 1.5-V power reference layers under the DDR3 routing region(1) 1
PS5 Number of reference plane cuts allowed within DDR routing region(2) 0
PS6 Number of layers between DDR3 routing layer and reference plane(3) 0
PS7 PCB routing feature size 4 Mils
PS8 PCB trace width, w 4 Mils
PS9 Single-ended impedance, Zo 50 75 Ω
PS10 Impedance control(5) Z-5 Z Z+5 Ω
  1. Ground reference layers are preferred over power reference layers. Be sure to include bypass caps to accommodate reference layer return current as the trace routes switch routing layers.
  2. No traces should cross reference plane cuts within the DDR routing region. High-speed signal traces crossing reference plane cuts create large return current paths which can lead to excessive crosstalk and EMI radiation.
  3. Reference planes are to be directly adjacent to the signal plane to minimize the size of the return current loop.
  4. An 18-mil pad assumes Via Channel is the most economical BGA escape. A 20-mil pad may be used if additional layers are available for power routing. An 18-mil pad is required for minimum layer count escape.
  5. Z is the nominal singled-ended impedance selected for the PCB specified by PS9.
