IT3 series high-speed (10+Gbps) ball grid array (BGA) mezzanine connectors

Hirose's IT3 mezzanine connector system is a unique 3 piece system consisting of a mating receptacle, mounting receptacle and a interposer assembly.

IT3 is as comfortable in today's data rates of PCIe and XAUI as it is in tomorrow's 10+ Gbps systems. With the ability to transmit differential, single-ended, and power through one package and being stackable from 15 - 40mm, IT3 can solve your interface needs for both current and future generations.

Features and Benefits

The IT3’s divided receptacle structure reduces thermal stress and ensures long term reliability of the BGA ball connection with the printed circuit board. The receptacle contact is strategically positioned into the solder ball preventing peel off and allowing greater protection against severe shocks and vibration. The mating contacts feature a pre-load structure that gives lower insertion and extraction forces ensuring a smoother mating and unmating operation. The innovatively styled housing prevents the exposure of the contacts to minimise damage.

Mechanical Features

• Unique 3-piece structure for flexibility
• Stacking heights from 15 to 40mm (15mm height is 2-peice)
• Staggered 1.5mm X 1.75mm ball grid array
• Number of contacts: 100, 200 & 300 signal + 90% additional grounds
  
• Differential, single-ended and power
• Low mating/extracting forces
• Wide misalignment tolerances for multiple connector use
• Both of SnPb and Pb-free are available
• Excellent reflow solderability

Signal Integrity Features

• Insertion loss to Crosstalk Ratio (ICR)

The ICR performance meets the extrapolated IEEE 802.3ap specification for 6.25Gbps with fully-populated pin assignment, and 10+ Gbps with skipped pin assignment.

Return Loss

The differential return loss meets the extrapolated IEEE 802.3ap specification up to 12GHz
