XMC+™, VITA™ 88 Standard Products

Overview

Based on XMC™, VITA™ 88.0 XMC+™ defines an alternative connector from the same family used in FMC™/FMC+™. While not intermateable with VITA™ 42.0 connectors, the VITA™ 88.0 connector is designed to be backwards compatible with VITA™ 42.0 electrical footprints. This allows designers to improve existing VITA™ 42.0 and/or VITA™ 61.0 designs by swapping connectors.

Next generation XMC+™ designs utilize an updated solder footprint and blade/beam style contact system. The result is superior SI supporting PCIe® 5.0 (32 GT/s) and 100 GbE operation, and improved mechanical performance and durability. All of this is achievable at stacks up to 18 mm.

VITA™ 88

VITA™ 88 - SEARAY™

Borrowing from the FMC/FMC+™ design community, the XMC+™ connector is a modified solder ball-equipped SEARAY™ that provides lower mating/unmating force and improved performance offered by blade & beam contacts.

VITA™ 88.0 XMC+™ connectors solder to existing VITA™ 42.0/VITA™ 61.0 electrical footprints, providing backward compatibility in most applications that adhere to traditional layout guidelines.
Elevated terminal and standard socket connectors improve channel performance and follow traditional XMC™ geometry.
Robust housing features protect contacts from stubbing or bent pins.
Rated at 1,000 cycles, the VITA™ 88.0 contact system increases mating durability over VITA™ 42.0/VITA™ 61.0, both rated at 500 cycles.
IPC Class 3 compliant solder charges available in both tin-lead and lead-free RoHS versions.
Available in 10 mm, 12 mm, 16 mm, and 18 mm stack heights.

VITA™ 88 - Standoffs

To achieve backwards electrical compatibility, VITA™ 88.0 utilizes a narrowed standoff to accommodate the alternate connector assemblies.

VITA™ 88.0 defines the use of specialized rectangular standoffs to accommodate the XMC+™ connectors.
Mechanically supports stack heights of 10 mm, 12 mm, 16 mm, and 18 mm.
