The GE Fanuc / ICS ICS-554E-4-MN is a 4-channel, 14-bit PMC ADC board delivering simultaneous sampling at up to 105 MHz per channel for high-speed signal acquisition and real-time processing. The module integrates four precision analog-to-digital converters with SNR exceeding 72 dB and SFDR greater than 85 dB, optional Graychip GC4016 quad digital down-converters for simultaneous processing of up to 16 arbitrary signal bands, and a user-programmable Xilinx FPGA with 3 million gates almost entirely available for custom signal processing logic.
## Technical Specifications
