## **MIL-HD2** 

## **NEXT GEN SOSA/VITA 91 ALIGNED CONNECTOR SERIES** 

## **Description** 

**MIL-HD2 is a robust solution for tighter card pitches and chassis designs, where space requirements and density are critical. These connectors are available in 3-, 4-, and 6-pair configurations: Providing the MIL embedded market with the highest count of differential pairs available today in a 3U configuration at 56Gb/s PAM 4 speeds.** 

**This series provides a SOSA aligned solution for next gen switch and payload card requirements enabling the MIL-embedded market to meet next gen performance levels while still meeting COTS requirements.** 

## **Benefits** 

- Data rates scalable to 56Gb/s PAM4 

- Highest density with 1.80mm pitch 

- Proven EMI and signal integrity advantages 

- Improved impedance matching 

- Enables hot plugging 

- Meets high density application requirements 

## **Features** 

- Configurations meet SOSA/VITA91 requirements for HD switch 

- • 4 diff, 8 column - SOSA aligned configuration 

- Proprietary crosstalk reducing technologies 

- 15.7mil drill compliant pin allows deeper backdrilling 

- Shielded contacts mate before signal contacts 

- Embedded capacitor available 

- Differential pairs 28-84 per inch (11-33 differential pairs/ cm) 

- Passed VITA 72 vibration level testing with BER monitoring
