Acqiris announced that its three new digitizer products feature a high-speed performance that is unmatched in the industry. The DC282, DC252 and DC222 PXI/CompactPCI digitizers offer a choice of front-end input mezzanines providing up to 3GHz input bandwidth or switchable high impedance input coupling.

According to the press release, the front-end flexibility, coupled with data conversion performance of single-channel 10bit sampling rates of up to 8GS/s, makes these platforms ideal for implementation in high resolution radar, lidar and ultrasound, as well as in semiconductor test and large scale physics research experiments.

The DC282 offers synchronous four-channel sampling at up to 2GS/s, or interleaved dual- or single-channel sampling at up to 4GS/s and 8GS/s, respectively. The dual-input channel DC252 and single-input channel DC222 digitizers offer the same 4GS/s dual-channel and 8GS/s single-channel sampling performance. Additionally, these devices are fully compliant with both PXI and CompactPCI standards, and incorporate the company's proprietary XLFidelity and JetSpeed II ADC chipsets, designed specifically to optimize high-speed ADC performance.

The XLFidelity ADC front-end chipset consists of two companion ASICs that integrate signal conditioning, amplification and interleaving functions essential to high-speed data acquisition. JetSpeed II represents the next generation in Acqiris' ADC chipsets by enhancing high-speed ADC performance. The chipset supplies vital clock and synchronization signals, and handles the capture and memorization of acquired data to provide maximum data throughput to internal memory.

As with other Acqiris products, the entire front end of the DC282, DC252 and DC222 is mounted on a removable mezzanine card for fast and efficient replacement. Users also have the choice of standard, high-frequency or high-impedance front ends to tailor the digitizer module to their needs.
