Datasheet

The NeoPress high-speed mezzanine system from Molex is now in stock at Mouser Electronics . This modular press-fit solution includes tunable differential pairs, low stack heights, and compliant-pin terminations with a staggered interface configuration, and offers data rates up to 28 Gbps. The NeoPress system is ideal for new, space-constrained applications that demand higher speeds and smaller form factors.

The system provides compliant-pin termination while minimising near-end and far-end crosstalk, matching the signal integrity of NeoScale SMT connectors.

The compliant pin enables solderless termination, allowing designers to rework the board and maximise system utility without sacrificing signal integrity.

The NeoPress system’s modular triad wafer design includes high-speed differential pairs that can be tuned to 85- to 100-Ohm impedances, creating a flexible, customisable system.

The system’s mirror-image triad layout simplifies PCB routing, lowering system costs by decreasing the number of PCB layers required for signal routing.

System options include high-speed single-ended traces and low-speed single-ended lines and power contacts, allowing designers to conserve PCB real estate by supporting low- and high-speed signals and power requirements with one compact connector.

The system is available from Mouser Electronics in mated 84-triad plug and receptacle with a stack height of 13.50mm. The system is ideal for high-density telecommunications and networking devices, such as hubs, servers, NAS towers and rack-mount servers, and can also be used in industrial automation and medical applications.
