PRODUCTION DATA
The layer stack-up and copper weight for each layer is shown in Table 9-1. Small subplanes are allowed on signal routing layers to connect components to major subplanes on top and bottom layers if necessary.
LAYER NO. | LAYER NAME | COPPER WT. (oz.) | COMMENTS |
---|---|---|---|
1 | Side A—DMD only | 1.5 | DMD, escapes, low frequency signals, power subplanes |
2 | Ground | 1 | Solid ground plane (net GND) |
3 | Signal | 0.5 | 50Ω and 100Ω differential signals |
4 | Ground | 1 | Solid ground plane (net GND) |
5 | VDD and VDDI | 1 | +1.8V power plane |
6 | Signal | 0.5 | 50Ω and 100Ω differential signals |
7 | Ground | 1 | Solid ground plane (net GND) |
8 | Side B—All other Components | 1.5 | Discrete components, low frequency signals, power subplanes |
