What is the Delta Sigma Analog Input Card?

Concurrent’s CP-AD3224 is a 32-channel analog to digital 24-bit delta sigma converter card with a PCI Express interface. The card is implemented using Cirrus Logic CS5368 delta-sigma converters. Each converter has an independently selectable clock source generated by a low jitter PLL. The interface is fully differential right up to the converter inputs for low noise and accurate measurements. Multiboard clocking and synchronization is supported. A RedHawk™ Linux® driver with extensive API including DMA and interrupt support is available for both 32-bit and 64-bit architectures.
