STRADA Whisper Backplane Connector Family

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 25 Gbps and offers unparalleled scalability up to 56 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 do not 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.

Mechanical Robustness

Signal contacts are arranged horizontally in highspeed 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.

The 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.

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 un-mate condition.
