Description

 

The FMC-ADC500CD is a cutting-edge HPC FMC module that offers 4 channels of high sampling rate and high-resolution ADC and DAC. Both the ADC and DAC interface to a carrier board using a JESD204B interface. The inputs of the ADC and the outputs of the DAC can be changed from AC coupled to DC coupled on the fly.

This board is designed for high-performance data acquisition and signal generation applications that require precise synchronization and low latency. It features the following components:

  • HMC7044 from ADI: This is the main clock distribution IC that provides multiple clock outputs with SYSREF signals. It can clock JESD204B devices with subclass 1 synchronization.
  • ADS54J60 from TI: These are dual-channel, 16-bit, 1-GSPS ADCs that support JESD204B interface. They can operate at various sample rates and enable decimation for lower bandwidth applications.
  • DAC39J84 from TI: This is a quad-channel, 16-bit, 2.8-GSPS DAC that supports JESD204B interface. It can generate direct IF or RF signals with high dynamic range and low distortion.
  • External trigger input: This allows adding timestamps to the sample stream from the ADCs for accurate timing measurements.
  • Internal VCXO and TCXO clocks: These provide stable and low-jitter reference clocks for the board. The HMC7044 also generates SYSREF signals with known and adjustable delay for JESD204B synchronization.

 

With this board, you can achieve high-speed data conversion, signal generation, and synchronization for your applications. It is ideal for radar, wireless communication, test and measurement, and other demanding scenarios.

Features

 

  • Two dual-channel ADS54J60 ADCs: These are 16-bit, 1-GSPS ADCs that support JESD204B interface. They can operate at various sample rates and enable decimation for lower bandwidth applications.
  • One quad-channel DAC39J84 DAC: This is a 16-bit, 2.8-GSPS DAC that supports JESD204B interface. It can generate direct IF or RF signals with high dynamic range and low distortion.
  • JESD204B interface via HPC connector: This provides 8 lanes of 12-Gbps data transfer per lane between the ADCs, DAC, and FPGA.
  • HMC7044 clock generator: This is a high-performance, 3.2-GHz clock generator that provides multiple clock outputs with SYSREF signals. It can clock JESD204B devices with subclass 1 synchronisation.
  • External trigger input: This allows adding time stamps to the sample stream from the ADCs for accurate timing measurements. It has a logic LVTTL 3.3-V level.
  • External clock input: This can be used as a reference clock or a main device clock input for the board. It can be connected to an external source or an internal VCXO or TCXO.
  • 10 SSMC input connectors: These are used for the following purposes:
  • 4 for single-ended input of ADC signal, with a frequency range of DC to 500 MHz.
  • 4 for single-ended output of DAC signal, with a frequency range of 10 to 1.25 GHz.
  • 1 for trigger input, with a logic level.
  • 1 for clock input, which can be used as a reference for the DAC and ADC via PLL.
  • JESD204B subclass 1 capability: This means that the board can achieve precise synchronisation and deterministic latency between multiple JESD204B devices using REF CLK and SYSREF signals.
  • 100-MHz ±12-ppm onboard VCXO: This is a voltage-controlled crystal oscillator that provides a stable and low-jitter reference clock for the board.
  • 10-MHz ±1.5-ppm onboard TCXO: This is a temperature-compensated crystal oscillator that provides another option for a reference clock for the board.
  • RF inputs: These are single-ended, 50-Ohm, 1.9-Vpk-pk inputs that can be DC or AC coupled (selected by firmware).
  • RF outputs: These are single-ended, 50-Ohm, 1-Vp-p outputs that can generate IF or RF signals.
  • Vadj supported voltages: These are 1.8 V, 2.5 V, and 3.3 V, which can be used to power different components on the board.
  • Power consumption: This is TBD (to be determined).
