LaFox, Ill. - Richardson RFPD, Inc. announced today the availability and full design support capabilities for a new dual, 16-bit analog-to-digital converter with sampling speeds of up to 310 MSPS from Analog Devices, Inc.
The AD9652 is designed to support demanding, high speed signal processing applications that require exceptional dynamic range over a wide input frequency range (up to 465 MHz). A low noise floor of -157.6 dBFS and a large signal spurious-free dynamic range (SFDR) performance exceeding 85 dBFS, typical, allow low level signals to be resolved in the presence of large signals.
The dual ADC cores feature a multistage, pipelined architecture with integrated output error correction logic. A high performance on-chip buffer and internal voltage reference simplify the interface to external driving circuitry, while preserving performance of the ADC.
The AD9652 is ideally suited for military radar and communications, multimode digital receivers (3G or 4G), test and instrumentation, and smart antenna system applications.
According to ADI, additional key features of the AD9652 include:
· High dynamic range
o SNR: 75.0 dBFS at 70 MHz (AIN = -1 dBFS)
o SFDR: 87 dBc at 70 MHz (AIN = -1 dBFS)
o Noise spectral density (NSD): -156.7 dBFS/Hz input noise at -1 dBFS at 70 MHz
o NSD: -157.6 dBFS/Hz for small signal at −7 dBFS at 70 MHz
o 90 dB channel isolation/crosstalk
o On-chip dithering (improves small signal linearity)
· IF sampling performance
o SNR: 73.7 dBFS at 170 MHz (AIN = -1 dBFS)
o SFDR: 85 dBc at 170 MHz (AIN = -1 dBFS)
o Full power bandwidth of 465 MHz
· On-chip 3.3V buffer, programmable input span of 2 V p-p to 2.5 V p-p (default)
· Differential clock input receiver with 1, 2, 4 and 8 integer inputs (clock divider input accepts up to 1.24 GHz)
· Internal ADC clock duty cycle stabilizer
· SYNC input allows multichip synchronization
· Total power consumption: 2.16W (3.3V and 1.8V supply voltages)
· DDR LVDS (ANSI-644 levels) outputs
· Serial port control
· Energy saving power-down modes
