Layout considerations
The layout for the demoboard is designed on a 4 layer PCB. The layers are numbered: top layer 1, bottom layer
2, buried layer top 3 and buried layer bottom 4. The copper on the layers is 35
μ
m thick, the space between the
layers is 0.435 and 0.5 mm. The material is FR4, with relative dielectric constant
ε
r
=4.3. No buried via’s are
used. The use of the layers is ordered as follows (from top to bottom)
Layer 1, top: Signal
Layer 3, buried top: Global GND, except at TZA3005, where it carries the TTL lines
Layer 4, buried bottom: Global GND
Layer 2, bottom: Signal.
A global GND is used, mostly at layer 3 and 4
Under all high speed ICs the GND layers are connected with multiple as-large-as-possible vias, to reduce
parasitic inductance between the GND planes.
The supply lines of the board are configured as star from connector to ICs/blocks.
The decoupling of all ICs/blocks is done with a two stage pi network: from the connector an individual line goes to
the first pi network near the IC/block. Then all the voltage domains are individually decoupled by a pi filter. This
filter is placed near the voltage domain pin. The last capacitor is placed as close as possible to the IC/block.
Fig.5 General setup of power supply decoupling network: From the global domain a pi filter provides the voltage for the local
voltage domains. Capacitor C2 is placed as close as possible to the IC to reduce parasitic inductance.
