VITA 57.1 FMC LPC ConnectorThe ML605 implements both the High Pin Count (HPC, J64) and Low Pin Count (LPC, J63)connector options of VITA 57.1.1 FMC specification. This section discusses the FMC LPCJ63 connector.Note: The FMC LPC J63 connector is a keyed connector oriented so that a plug-on card faces awayfrom the ML605 board.The FMC standard calls for two connector densities: a High Pin Count (HPC) and a LowPin Count (LPC) implementation. A common 10 x 40 position (400 pin locations) connectorform factor is used for both versions. The HPC version is fully populated with 400 pinspresent, and the LPC version is partially populated with 160 pins.The 10 x 40 rows of a FMC LPC connector provides connectivity for:• 68 single-ended or 34 differential user defined signals• 1 MGT• 1 MGT clock• 2 differential clocks• 61 ground, 10 power connectionsOf the above signal and clock connectivity capability, the ML605 implements the full set:• 34 differential user-defined pairs:• 34 LA pairs• 1 MGT• 1 MGT clock• 2 differential clocksSignaling Speed Ratings:• Single-ended: 9 GHz / 18 Gb/s• Differential• Optimal Vertical: 9 GHz / 18 Gb/s• Optimal Horizontal: 16 GHz / 32 Gb/s• High Density Vertical 7 GHz / 15 Gb/sMechanical specifications:• Samtec SEAM/SEAF Series• 1.27mm x 1.27mm (0.050" x 0.050") pitchThe Samtec connector system is rated for signaling speeds up to 9 GHz (18 Gb/s) based ona -3 dB insertion loss point within a two-level signaling environment.Note: The ML605 board VADJ voltage for the FMC HPC and LPC connectors (J64 and J63) is fixedat 2.5V (non-adjustable). The 2.5V rail cannot be turned off. The ML605 VITA 57.1 FMC interfacesare compatible with 2.5V mezzanine cards capable of supporting 2.5V VADJ.Send Feedback
