TXMC639 – XMC FPGA Module with 16-Ch Analog Input, 8-Ch Analog Output by TEWS Technologies

The TEWS Technologies TXMC639 is a single-width Switched Mezzanine Card (XMC) module built around a user-configurable AMD Kintex 7 FPGA — available as XC7K160T (-10R) or XC7K325T (-11R) — delivering a comprehensive analog and digital I/O platform for defence signal processing, industrial automation, and real-time control system designers. The ADC input channels are based on the Linear LTC2320-16 octal 16-bit 1.5 Msps differential ADC: the TXMC639-11R provides 16 channels while the TXMC639-10R provides 8, with configurable differential input voltage ranges of ±20.57V, ±10.28V, or ±5.14V and factory correction values for gain and offset error. DAC output channels use the Analog Devices AD5547 dual 16-bit DAC: the TXMC639-11R provides 8 outputs and the TXMC639-10R 4, each with programmable output ranges of ±10V, ±5V, or ±2.5V and 1 µs typical full-scale settling time. Thirty-two ESD-protected TTL I/O lines are individually programmable as input or output, with 16 lines optionally switchable to RS422 differential interface with individual internal terminations. For rear I/O expansion and inter-board communication, P14 provides 64 single-ended or 32 differential FPGA I/O lines, and P16 hosts four Multi-Gigabit Transceivers. The user FPGA connects to 1 GB DDR3L SDRAM via an internal Kintex 7 memory controller. FPGA configuration uses serial SPI flash with AMD Tandem Configuration support, and JTAG in-circuit debugging is available. Software drivers cover Linux, Windows, VxWorks, QNX, and Integrity. The TXMC639 operates from -40 to +85 °C with an MTBF of 157,000 hours. Available from Recab, your Nordic partner for TEWS Technologies embedded I/O solutions.
