National Instruments PXIe-7903 High-Speed Serial Instrument with 12 Mini-SAS HD Connectors and 28.2 Gb/s Data Rate for 48 Bidirectional Digital Channels

国家仪器 PXIe-7903 高速串行仪器

PXIe-7903(部件编号:788917-01)是National Instruments公司推出的一种多功能高速串行仪器.通过可重新配置的XCVU11P FPGA,该设备能够进行高性能协处理,是需要增强协议验证和接口的应用程序的绝佳选择.NI PXIe-7903拥有许多有用的功能,并且能够轻松实现各种高速串行协议.这种串行仪器的设计确实非常灵活——LabVIEW FPGA模块可以根据用户的具体需求来编程.

为了实现连接性,NI PXIe-7903前面板配备了各种各样的连接器类型.12个迷你-SAS HD连接器提供了一个非常高的速度串行接口,数据传输率从500 Mb/s到28.2 Gb/s不等.这些连接器端口被标记为0-11,以区分PXIe-7903的电缆兼容性——端口0到7仅与被动铜电缆兼容,而端口8到11可以与被动电缆和带电光电缆一起使用.

The front panel of the NI PXIe-7903 Serial Instrument also features two SMA female connector types, labeled CLK IN and CLK OUT. The CLK IN port provides input for the reference clock of the PXIe-7903, boasting AC input coupling and a frequency range of 10 MHz to 300 MHz. The CLK OUT port it the reference clock’s output terminal. It features a nominal output impedance of 50 Ω and an output voltage range of 0.61 V to 1.04 V peak-to-peak.

The final connector on the front panel of the NI PXIe-7903 is a Mini-HDMI, which provides secure connections to the 8 Digital I/O channels of the device. These single-ended signals have a maximum frequency of 60 MHz, enabling signal direction control per channel.

设计尺寸为2槽PXIe模块,NI PXIe-7903在不包括连接器时测量尺寸为21.6厘米× 4.1厘米× 13.0厘米(8.5英寸× 1.6英寸× 5.1英寸).该串行仪器重量为1134克(40.0盎司),最大总功率为164瓦.
