STRADA WHISPER Backplane Connectors Blinding Speeds 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 56 Gbps and offers unparalleled scalability up to 112 Gbps—allowing you to achieve efficient future system upgrades without costly backplane or midplane redesigns. Performance Matters 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 total system impedance design. 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. Your Design Partner For 112 Gbps Architectures To ensure smooth transitions from 10 Gbps to 112 Gbps systems using the STRADA Whisper connector, TE Connectivity (TE) can assign a team of experts—comprised of our 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, direct plug orthogonal, or a cabled-backplane system, TE can tailor the STRADA Whisper product portfolio to best fit and enable your system architecture.

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. Fig. 1. Close up of signal contacts 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. Horizontal-Shield Springs Wide Paddle Tips C-shaped shields protrude outwards to protect signal pins from damage. DATA AND DEVICES /// STRADA WHISPER BACKPLANE CONNECTORS 360-Shield Springs Tabs on the sides of C-shield assure that ground contacts have at least a 2.5mm wipe, which helps maintain electrical performance with 1.5mm of unmate condition.
