SMA Connectors (Differential)
A high-precision clock signal can be provided to the FPGA using differential clock signals
through the onboard 50
Ω SMA connectors J38 (N) and J41 (P).
8. Multi-Gigabit Transceivers (GTP MGTs)
The SP605 provides access to 4 MGTs.
• One (1) MGT is wired to the PCIe x1 Endpoint (P4) edge connector fingers
• One (1) MGT is wired to the FMC LPC connector (J2)
• One (1) MGT is wired to MGT SMA connectors (J36, J37)
• One (1) MGT is wired to the SFP Module connector (P2)
The SP605 includes a set of six SMA connectors for the GTP (MGT) RX/TX Port and GTP
(MGT) Clock as described in
Figure 1-10 and Table 1-10 .
