Backplane connector transfers data at 25 Gbps

The STRADA Whisper backplane family was designed with your end customer’s need for high-performing, high bandwidth systems in mind. Its revolutionary design transfers data at blinding speeds of 25 Gbps and offers unparalleled scalability up to 40 Gbps—allowing you to achieve efficient future system upgrades without costly backplane or midplane redesigns.

The STRADA Whisper product family operates with extremely low noise, low insertion loss and little to no skew—all of which provide system architects with design flexibility and high design margin. Specific versions are available for
100-Ohm and 85-Ohm applications so you don’t have to compromise on impedance discontinuities.

Mechanically, the STRADA Whisper connector family mirrors most high-speed backplane connectors in the market for easy implementation. It differentiates itself through folded signal pins surrounded by strong, protective C-shaped
shields, which make the product family one of the most robust offerings in the market. Additionally, the connector footprint keeps crosstalk down and the overall connector design uses latest eye-of-needle (EON) technology.

To ensure smooth transitions from 10-Gbps to 25-Gbps systems using the STRADA Whisper connector, TE can assign a team of experts—comprised of their best signal integrity and mechanical engineers—to help you develop
a solution that fits right into your architecture. Whether it’s traditional backplane, orthogonal midplane, or a cabled-backplane system, TE can tailor the STRADA Whisper product portfolio to best fit and enable your system architecture.

Signal contacts are arranged horizontally in high-speed differential pairs for zero skew. This makes your board design simpler, while increasing signal integrity performance and saving board space. Each differential pair is surrounded by
six ground connection points.

Contacts have wide paddle tips to ensure maximum contact surface area for added robustness when mating with the header pin. Signal contacts have two points of contact for long-term reliability. Horizontal- and 360-shield springs surround the contacts for improved electrical performance.

Connector allows for 1.5mm worth of mating separation (between both the ground and signal) through TE’s patented C-shaped, 360-grounding design, which includes an extra “orphan” shield at the bottom of the horizontal stack of contacts for complete shielding. The 360-ground shield provides high signal integrity margin, (electrical margin) granting you more chip and PCB flexibility. C-shaped shields protrude outwards to protect signal pins from damage.
