Description
The National Instruments AT-1212 Signal Generator Adapter Module for FlexRIO, part number 782248-02, is designed for high-performance signal generation with its DC-coupled single-ended inputs and a maximum update rate of 1.25 GS/s. This module features two AO (analog output) channels, each capable of providing an analog output voltage range from -2 V to 2 V, and boasts a high 14-bit analog output resolution, ensuring precise signal generation within a 480 MHz analog bandwidth.
Designed to be compatible with FlexRIO FPGA modules, the AT-1212 enhances system capabilities with its two digital-to-analog converters (DACs) and two LVDS input ports, the latter of which houses 14 differential LVDS signals each to support complex applications. An integrated clock generator, powered by a 25 MHz TCXO source clock, provides synchronization and timing to the DACs, ensuring reliable operation.
The onboard microcontroller (uController) is a critical component that manages power-up sequencing, oversees the clock generation registers, and fine-tunes the DAC parameters, contributing to the module’s consistent performance and stability during operation.
