Embodiment Construction

[0009] The present invention will be further described below in conjunction with accompanying drawing:

[0010] refer to figure 1 , this design is a high-speed analog-digital signal acquisition and processing and data Storage and processing board, supports two channels of intermediate frequency synchronous analog-digital signal sampling, supports up to 250MSps analog-digital sampling rate, and supports external sampling clock.

[0011] This design processes digital signals through FPGA and DSP, and imports the data into high-speed dynamic random access memory (hereinafter referred to as DDR3SDRAM) for storage.

[0012] It uses Ethernet interface (that is, RJ45 interface), PCI-express connector and USB interface to exchange data with the outside.

[0013] Provide DDR3SDRAM and other kinds of memory for data storage.

[0014] The circuit design principle of the present invention: two analog signals are respectively connected to two differential amplifiers by SMA interface 1 a...

Abstract

The invention discloses a double-channel high-speed analog digital signal collecting and processing board card. The board card comprises an FPGA, a DSP, four DDR3 SDRAMs, two SPI EEPROMs, two SPI FLASHs, two differential amplifiers, an analog-digital converter, an NAND FLASH, an Ethernet transceiver, a PCI-express connector, a clock selecting chip and clock managing chips, wherein the clock selecting chip and the clock managing chips are connected with clocks respectively. The mature and reliable components are adopted in the design, the normative circuit design is supplemented, and accuracy and efficiency of signal collecting and processing are ensured. The standard 3U board card size is adopted and can be matched with a standard 3U case. The standard PCI-express connector is adopted to be in butt joint with a case or a board card with a corresponding interface conveniently to achieve data interaction between the signal collecting and processing board card and other structures of a system.
