Product Details

The AD9652 is a dual, 16-bit analog-to-digital converter (ADC) with sampling speeds of up to 310 MSPS. It 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). Its exceptional low noise floor of −157.6 dBFS and large signal spurious-free dynamic range (SFDR) performance (exceeding 85 dBFS, typical) allows 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 inter-face to external driving circuitry while preserving the exceptional performance of the ADC.

The AD9652 can support input clock frequencies of up to 1.24 GHz with a 1, 2, 4, and 8 integer clock divider used to generate the ADC sample clock. A duty cycle stabilizer is provided to compensate for variations in the ADC clock duty cycle. The 16-bit output data (with an overrange bit) from each ADC is interleaved onto a single LVDS output port along with a double data rate (DDR) clock. Programming for setup and control are accomplished using a 3-wire SPI-compatible serial interface.

The AD9652 is available in a 144-ball CSP_BGA and is specified over the industrial temperature range of −40°C to +85°C. This product is protected by pending U.S. patents.

EVAL-AD-FMCOMMS6-EBZ Circuit Diagram


Product Details

The AD-FMCOMMS6-EBZ eval board is a 400MHz to 4.4GHz receiver based on the AD9652 dual 16bit analog to digital converter, the ADL5566 High Dynamic Range RF/IF Dual Differential Amplifier and the ADL5380 quadrature demodulator.

This is an I and Q demodulation approach to direct convert (also known as a homodyne or zero IF) receiver architecture. Direct conversion radios perform just one frequency translation compared to a super-heterodyne receiver that can perform several frequency translations. One frequency translation is advantageous because it:

  • Reduces receiver complexity and the number of stages needed, increasing performance and reducing power consumption
  • Avoids image rejection issues and unwanted mixing

This topology will provide image rejection and early implementation of the differential signal environment. There is an amplification stage to maintain the full-scale input to the ACD. The local oscillator and ADC clock are on board and share the same reference signal prevent smearing. The form factor is VITA57 compliant and all of the DC power is routed from the data capture board through an FMC connector. This evaluation board demonstrates a high performance receiver signal chain aimed at military and commercial radar using “commercial off the shelf” (COTS) components. The overall circuit has a bandwidth of 220MHz with a pass band flatness of +/_ 1.0 dB. The SNR and SFDR measured at an IF of 145MHz are 64dB and 75dBc, respectively.
