VPX2IP IP0/IP1 connectivity options
To provide local control and enable maximum designer flexibility, Dynamic Engineering
allows engineers to specify resistor stuffing options to reconfigure the connectivity
between IP0 and IP1 carrier I/O and the two 50 pin Condo header or VPX connector,
see Figure 6 for an illustration. Please contact Dynamic Engineering if you desire a non-
standard trace/stuffing option/configuration.

Notes:
1) VPX_P0 (Power, JTAG, Reset, Global Address) and VPX_P1 (PCI Express) not shown are always stuffed.
2) Option 1 - Condo Header with Bezel, no rear IO(VPX_P2) - R0 & R3 are 0 ohm and R1, R2 & R4 are open.
3) Option 2 - Rear IO, no Condo Header with blank Bezel - R1 & R2 are 0 ohm and R0, R3 & R4 are open
a) Standard Rear IO option connects all 32 VPX pairs
4) Differential bus traces are length/impedance matched – standard stuffing options leave virtually no-stub.
5) R0, R1, R2, R3, and R4 are 0402, 1/16W pads - contact Dynamic Engineering for custom stuffing options.
