68RT-SOSA-DEBUG Data Sheet

FUNCTION/FEATURES

• Designed for debug and validation of SOSA™-aligned VPX cards
• Industry standard commercial connectors, where applicable
• Dual SFP+ cages for 10GbE KX SerDes signal access (J8, J9)
• RJ45 GbE (J1), USB 3.0 (J3), Mini DisplayPort video (J2) (9-pin D-Sub RS-232 console (J10), IPMB I2C, SATA debug)

DESCRIPTION

The 68RT-SOSA-DEBUG is the SOSA™-aligned 3U OpenVPX Debug RTM designed for engineering validation and debug of SOSA-aligned VPX SBCs. The 68RT-SOSA-DEBUG routes all RP0, RP1, and RP2 rear I/O signals to industry-standard front-panel connectors including dual SFP+, RJ45 GbE, stacked USB 3.0, Mini DisplayPort, and 9-pin D-Sub serial, providing comprehensive signal access during development and qualification testing.

The 68RT-SOSA-DEBUG is a non-standard ‘extended’ RTM size and does not have proper mechanical securing/interface in a standard commercial chassis.

68RT-SOSA-DEBUG INSTALLATION

Note

For reference only.

68RT-SOSA-DEBUG CONNECTOR/PIN-OUT INFORMATION

I/O Connectors

User and defined I/O is available through panel mounted and inboard header connectors via the VPX RP0, RP1 & RP2 user defined rear I/O backplane connectors. The 68RT-SOSA-DEBUG RTM is designed for debug and validation of SOSA™-aligned 3U OpenVPX SBC I/O cards. All RP0, RP1, and RP2 signals are routed to accessible front-panel and inboard connectors for engineering debug and validation.

Caution

Do not connect to any undesignated or n/c pins.

Note

The following notes apply unless otherwise specified:

1. Maximum ratings for the VPX MultiGig-RT2 type rear I/O connectors are as follows (per TE connectivity 108-2072, Rev F):
       • Operating Voltage: 166 volts AC peak or DC
       • Current: Signal Wafers: 1.5 ampere at <30°C (Single circuit, free air)
2. This document provides signal names for reference only and may be referring to the 68RT-SOSA-DEBUG board.
