National Instruments Corporation CDA-2990 8 Channel Clock Distribution Accessory with GPSDO
The National Instruments CDA-2990 is an 8-channel clock distribution accessory designed to provide precise timing and synchronization for PXI and PXI Express systems. It features an integrated GPS-disciplined oscillator (GPSDO) that enables high-accuracy clock generation and distribution, supporting applications that require tight synchronization across multiple devices or chassis. The CDA-2990 distributes a 10 MHz reference clock and PPS (pulse per second) signals to up to eight devices, ensuring minimal phase drift and high stability. The accessory is ideal for test, measurement, and data acquisition systems where reliable and accurate timing is critical. The GPSDO functionality allows the CDA-2990 to maintain long-term frequency accuracy by locking to GPS signals, making it suitable for geographically distributed or mobile test setups. The device is designed for easy integration with NI hardware and software platforms, supporting seamless configuration and monitoring through NI sof
