VMETRO in Houston is announcing a trio of I/O modules for its FPGA-based PCI mezzanine card (PMC) products. Users can choose the front-end processing appropriate to the application from a dual-channel 105 megasamples per second (MSPS) analog input, a dual-channel 210 MSPS analog output, or a RS485 module. All three I/O modules integrate into a VMETRO PMC-FPGA03, PMC-FPGA05 or DEV-FPGA05 card. These field-programmable-gate-array (FPGA)-based PMC/PCI boards feature Xilinx Virtex-II Pro or Virtex-5 FPGAs and memory banks directly connected to the FPGA for signal and data processing in computationally intensive applications. Designed for DSP applications including software-defined radio (SDR), these products provide processing and I/O in a single, compact, and flexible platform. The ADC-MOD1 module has a dual-channel 105 MSPS 14-bit analog front-end. It includes an on-module 105 MHz sample clock and the ability to accept an external reference and trigger input. Four pairs of LVDS I/O are provided for general-purpose use, such as synchronizing multiple boards. Complementing the analog input module is a dual-channel 210 MSPS 14-bit analog output module. The DAC-MOD1 module also has provision for an external clock source, trigger input, and general LVDS I/O signals. The product also features a 210 MHz on-module oscillator. The third module, the RS485-MOD2, is a 33-channel RS485/RS422 transceiver. For flexibility, all channels can be programmed to be inputs or outputs. Applications for this module include digital-camera interfaces and general-purpose control. For more information contact VMETRO online at www.vmetro.com.
