3.0 Description of Development Kit
Components
A. PCB Test Boards with Header and SMA Connectors
Each PCB test board is designed with 50Ω signal traces routed from SMT SMA’s to
the latch/eject header...
Optional calibration traces included (50 Ω Single-ended)

Four each 50Ω single-ended lines (identified S1, S2, S3 and S4)
Four each 100Ω Differential lines (S5P/S5N, S6P/S6N, S7P/S7N, S8P/S8N)
Note 1: two 50Ω single-ended lines are used to drive 100Ω differential lines.
Note 2: “P” = positive signal and “N”= negative sign is for reference only.
Note 3: Header pins (between S2 and S3) and (S6P/S6N and S7P/S7N) are
grounded (see crosstalk setup in section 4.0).
