8-bit 1000 MSPS ADC and a track-and-hold amplifier in a chip

Hittite Microwave has introduced Multi-GHz analog to digital quantizer chip to quantize DC to RF and microwave signals up to 18 GHz, making it suitable for designing 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 1000 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 Vp-p full scale level.

To enable rapid prototyping of the Multi-GHz Quantizer, Hittite offers both the EVAL01-HMC9000 and the EKIT01-HMC9000 evaluation platforms. The EVAL01-HMC9000 is a fully populated evaluation PCB which includes the HMC9000 Multi-GHz quantizer and other key supporting circuitry such as Hittite's HMC988LP3E and HMC1034LP6GE. 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.

The full EKIT01-HMC9000 evaluation and application reference kit expands on the EVAL01-HMC9000 and adds a hardware platform based on the Xilinx Spartan-6 FPGA. The EKIT01-HMC9000 reference kit includes complete software and hardware user guides as well as complete design and layout files. Hittite's 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. Samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via the company's site at www.hittite.com.
