The ICS-1745 is a high-speed acoustic ADC module in the 3U cPCI form factor. Derived from the popular ICS-645D, the ICS-1745 is intended for space, weight, and power sensitive high frequency sonar applications. Remote mine hunting systems based on unmanned or autonomous underwater vehicles (UUVs/AUVs) are a prime example.

The eight analog input channels are sampled at up to 5 MHz with 16-bit resolution. Each channel includes signal conditioning circuitry consisting of programmable gain control (four ranges) and a fixed frequency anti-alias filter. The filters on the standard version of the product have cut-off frequencies of 1.25 MHz; as an option, the frequencies can be changed. Multiple cards can be easily combined to provide synchronous sampling across larger numbers of channels. All control and data I/O is accomplished using the PCI 2.2 interface (64-bit, 66 MHz) which supports universal signaling (5V/3.3V). The PCI Bus master interface on the board provides chained (scatter-gather) and non-chain mode burst transfers. The ICS-1745 provides 16 MBytes of synchronous SRAM buffer memory.
