Functioning as a comprehensive cross-correlator, the XCM_64X64 facilitates efficient and precise signal processing required in synthetic radar receivers and advanced spectrometers. Designed on IBM's 45nm SOI CMOS technology, it supports ultra-low power operation at about 1.5W for the entire array, with a sampling performance of 1GSps across a bandwidth of 10MHz to 500MHz. The ASIC is engineered to manage high-throughput data channels, a vital component for high-energy physics and space observation instruments.
