TE Connectivity – High-performance backplane connectors support data rates up to 56Gbits/s

The broad portfolio of high-speed backplane connectors from TE Connectivity (TE) provides system designers with the flexibility they require to meet the challenges of their application.

For the most demanding applications operating at data rates up to 56Gbits/s, the STRADA Whisper connector portfolio is available in four, six and eight pairs per column, supporting a card pitch of 16.4mm, 20.4mm and 25.4mm. The connectors provide a density of up to 20 differential pairs/cm.

The Z-PACK HM-Zd and Z-PACK HM-Zd Plus connectors support data rates up to 12.5Gbits/s with two, three or four pairs per column. The Z-PACK HM-Zd Plus products provide better signal integrity in a design that is backwards-compatible with Z-PACK HM-Zd products. These connectors support the Advanced Differential Fabric (ADF) connector specified in the PICMG 3.x Advanced TCA specifications.

Z-PACK HS3 connectors support data rates up to 6.25Gbits/s for both single-ended and differential signals.

TE’s MULTIGIG RT connector provides a pinless backplane connection with a PCB construction which gives the connector system the flexibility to combine 100Ω differential, 50Ω single-ended, open pin field and power wafers in one connector module.

The 100Ω IMPACT connectors support high data rates up to 25Gbits/s.

The 85Ω impedance version of the Z-PACK TinMan connector conforms to the QPCle and Intel QPI standards.

Z-PACK Slim UHD connectors have a low profile, at just 12.5mm wide, and accommodate 55 lines/cm.
