EOL - 4-Channel, 160/180 MHz 16-bit ADC PMC Module with Virtex-5 SX95T User Programmable FPGA
Product phased out. Please call systerra for replacement options.

Designed for communications, radar and test & measurement applications, the ICS-1555 builds on the legacy of the industryleading ICS-554 and ICS-1554 digital receiver family to provide unsurpassed ADC technology with industry-leading DSP expertise. The result is a cost-effective combination of size and performance in a single PMC site.

The ICS-1555 consists of four 16-bit ADCs sampling synchronously at frequencies up to 160 MHz or 180 MHz. Simultaneous down conversion of up to 16 arbitrary signal bands is provided by four Graychip GC4016 digital down-converters (DDCs). A Xilinx Virtex-5 SX95T FPGA is provided for user-defined signal processing functions, giving greater capacity and lower power consumption than previous generations.

The DDCs provide digital down-conversion f up to 16 narrowband, eight Split-I/Q or four wideband channels that can be tuned to any arbitrary center frequency within the pass band. Output data can be in either real or complex format, providing a maximum bandwidth of 10 MHz (-1dB) on each channel. The sampling clock can be generated internally using the onboard Silicon Labs Si571, a modern Crystal Oscillator with programmable frequency and a stability of +20 ppm. The sampling clock can also be sourced externally by powering down the onboard oscillator and providing a clock input on the front panel connector. The external clock can be a sinewave or LVTTL signal with a frequency in the range of 32 MHz to 180 MHz.

The FPGA is not used for board control functions, thus providing maximum occupancy for customer applications. It provides a powerful signal processing capability that can be loaded with standard functions such as wideband DDC, FFT and time stamping, or programmed by the user for any required field.

The programmable clock can be referenced to an internal 10 MHz reference with a stability of ±1 ppm or referenced to an externally supplied clock in the range of 10 - 200 MHz. The product provides internal and external clock and trigger capability, and supports multiple board synchronous sampling both of ADC and DDC functionality.

A Hardware Development Kit (HDK) provides support for users who wish to implement their own signal processing algorithms in the FPGA. Alternatively, our FPGA applications programming team can develop FPGA cores specific to customer needs.
