Wideband Quantizer Solution

Analog Devices, the world class supplier of complete MMIC-based solutions for communication and military markets, has introduced a complete Multi-GHz Quantizer chip set that enables quantization of ultra-wideband signals from DC to 18 GHz with excellent linearity and low noise. This groundbreaking Multi-GHz Quantizer solution can facilitate unparalleled levels of performance in test and measurement systems, Bit Error Rate Testers (BERTs), and Pulse Detection Systems including Pulse Doppler Radars where wideband sampling capability is a necessity.

The HMC9000 Multi-GHz Quantizer chip set includes an 8-bit 1,000 MSPS ADC (Analog to Digital Converter) and a high-performance T/H (Track-and-Hold) amplifier which offers precision signal sampling over 18 GHz of input bandwidth. This combination of ADC and T/H delivers high linearity of >50 dB SFDR up to 7 GHz and low noise of >40 dB SNR up to 9 GHz at 1 VPP full-scale level. The HMC988LP3E is a Clock and Delay Control which ensures very accurate system sampling, while the HMC1034LP6GE PLL with Integrated VCO is used as the system clock and provides a total system jitter of only 100 fsrms.

Analog Devices' proprietary EasySuite™ firmware and software code simplifies configuration of the Multi-GHz Quantizer and enables the data-acquisition system designer to realize new levels of functionality and performance.

The HMC9000 Multi-GHz Quantizer chip set is available in SMT package format. See the above image in full size here.
