4 天之前 · Amphenol FCI MEG-Array® Mezzanine Connector System provides the high density and high speed of a large array supported by the reliability and cost-effectiveness of a standard surface mount PCB assembly. MEG-Array optimizes high-speed signal integrity at speeds exceeding 10GB/s through flexible ground distribution.

Schmitt-trigger input circuitry (TTL hysteresis) for B input allows jitter-free triggering from inputs with transition at rates as slow as 1 V/s, providing the circuit with excellent noise immunity, typically of 1.2 V. A high immunity to VCC noise, typically of 1.5 V, also is provided by internal latching circuitry.
