SiGe the technology enabler
LeCroy's silicon bandwidth advantage is due to years of accumulated experience with SiGe processes, most recently by obtaining 20 GHz of silicon bandwidth using 7HP SiGe. The latest ground-breaking LeCroy 36 GHz chipset is based on 8HP SiGe. SiGe is a widely adopted, mainstream, commercial process backed by chip technology leader IBM Semiconductor, with years of collective implementation knowledge and experience.
IBM's 8HP SiGe process is the fourth-generation SiGe process with two times the performance of the previous generation and up to 200 GHz transistor switching speeds. 8HP SiGe provides lower electrical noise for increased performance, which translates into a 3 to 4 dB baseline noise improvement compared to previously deployed 7HP SiGe. This equates to noise performance at 36 GHz, roughly equivalent to what is available in LeCroy or competitive 20 GHz oscilloscopes today. 8HP SiGe also provides lower power consumption, making possible a single acquisition module with twice the high bandwidth channel density available from other manufacturers.
DBI — pushing beyond raw chip bandwidth
DBI, a proprietary, patented LeCroy technology, provides the ability to double or triple the bandwidth available in raw silicon by splitting a high bandwidth signal into multiple paths of lower bandwidth, acquiring these lower bandwidth signals with best-in-class silicon chip technologies,
