TXMC639: XMC with User-Reconfigurable FPGA for Multi I/O

TEWS introduces TXMC639, the new XMC module featuring a user-configurable AMD Kintex 7 FPGA with up to 16 differential ADC input channels and 8 single-ended DAC output channels. Each ADC channel has 16-bit resolution and can operate at up to 1.5 Msps, with configurable differential input voltage ranges, while each DAC output is configurable as a single-ended bipolar analogue output with selectable voltage ranges. The module also offers 32 ESD-protected TTL lines for a flexible digital interface, all individually programmable as input or output. In addition, 16 of these TTL lines can be switched via the Board Configuration Controller (BCC) to provide 8 RS422 interfaces. TXMC639 FPGA is connected to a 1 GB DDR3L SDRAM and module configuration can be performed via SPI flash, BCC or JTAG interface, with support for PCIe specification compliance. The TXMC639 comes with the reference design of the FPGA board, which can be programmed via the integrated Board Configuration Controller (BCC). Programming via the JTAG interface using a USB programmer is also possible. In accordance with PCI specifications and PCI header data buffering, the content of the user FPGA can be changed during operation. TXMC639 module is the ideal COTS solution for industrial applications where specialised I/Os and guaranteed long-term availability of the FPGA-based design are required, enabling a fully customised interface.
