Derived from the popular ICS-645 product, the ICS-645B offers a cost effective solution for high frequency sonar (littoral and mine hunting applications) and test and measurement (vibration analysis, and jet engine testing) applications.

The ICS-645B provides synchronous sampling at up to 20 MSPS across all channels. It also features 16 MBytes of onboard storage, making it ideal for transient capture and high data throughput applications using non real-time operating systems such as Windows or Linux. The ICS-645B is a direct replacement for the earlier ICS-645 product that provides a 4x improvement in PCI throughput and memory capacity, and 2.5x improvement in FPDP throughput. Based on the Analog Devices AD9260 oversampling ADC, the ICS-645B can be configured for up to 32 channels of output at sampling frequencies of up to 20 MSPS. The PCI Bus is compatible with PCI 2.2 (64-bit, 66 MHz) and supports universal signaling (5V/3.3V). The PCI bus master interface on the board provides chained (scatter-gather) and non-chain mode burst transfers. As an alternative to the PCI bus, data may be routed through an FPDP II output port at up to 400 MBytes/second. When working with FPDP devices that do not support FPDP II, the interface will revert to ANSI/VITA 17 FPDP operation at up to 160 MBytes/second.
