DataLogger 100: Data Acquisition Powerhouse

DataLogger 100 isn't just another data acquisition system; it's a well-crafted powerhouse designed to tackle demanding high-speed data capture and generation tasks. This complete solution combines the processing prowess of a PCIe104Z+ carrier board with the high-performance capabilities of two specialized FMC+ mezzanine cards: the FMCP-ADC3P0 and the FMCP-DAC12P0. Let's delve deeper into how these components work together, leveraging the industry-standard JESD204B protocol to achieve exceptional data transfer rates and unparalleled precision.

The Engine Room: Zynq UltraScale+ MPSoC on the PCIe104Z+

At the heart of DataLogger 100 lies the PCIe104Z+ carrier board. This versatile board boasts a Xilinx Zynq UltraScale+ MPSoC (Multi-Processor System-on-Chip) from the C1156 package family. This powerful processor isn't just about raw processing muscle; it offers a heterogeneous architecture that integrates an ARM processing system with programmable logic resources. This unique combination provides the ideal platform for data acquisition applications. The ARM processors handle high-level tasks like system control and data analysis, while the programmable logic allows for real-time signal processing and custom hardware acceleration.

The Zynq's flexibility extends to its diverse range of interfaces. DataLogger PCIe104Z+ features a rich set of connectivity options, including Gigabit Ethernet, USB 3.0, and SATA, enabling seamless communication with external devices for data storage, control interfaces, or network connectivity. Additionally, the board boasts an FMC+ connector, providing a modular expansion slot for the FMCP-ADC3P0 and FMCP-DAC12P0 modules, the true stars of the high-speed data acquisition show.

The High-Speed Vanguard: FMCP-ADC3P0

The FMCP-ADC3P0 module acts as the data acquisition workhorse of DataLogger 100. This FMC+ compliant board packs a serious punch, housing four high-speed analog-to-digital converters (ADCs). These ADCs, either the AD9208 or AD9689BBPZ-2600 ICs, are the champions of speed and detail. Each ADC can capture analog signals at a staggering 3GS/sample per channel, with a resolution of 14 bits. Imagine capturing the intricate details of a high-frequency signal – that's the kind of power the FMCP-ADC3P0 brings to the table.

But raw speed isn't the only story. The FMCP-ADC3P0 leverages the power of JESD204B, a high-speed serial interface standard specifically designed for communication between converters and digital processors. JESD204B plays a crucial role in ensuring efficient and reliable data transfer between the high-speed ADCs and the Zynq processor:

• Serial Data Transmission: JESD204B utilizes a serial interface, meaning data travels as a single stream of bits instead of parallel channels. This approach maximizes efficiency, reducing the number of physical connections needed and minimizing potential signal integrity issues.
• Data Encoding and Signal Integrity: The standard specifies how digital data is converted into electrical signals suitable for high-speed transmission over the cable. It also defines parameters like voltage levels, impedance matching, and clock characteristics to ensure minimal signal distortion during transmission.
• Synchronization: JESD204B includes mechanisms for synchronization between the ADC and the Zynq processor. This ensures that all captured data samples are aligned correctly, allowing for accurate reconstruction of the original analog signal.

Precision Redefined: FMCP-DAC12P0

The FMCP-DAC12P0 module serves as the perfect complement to the FMCP-ADC3P0, taking care of the digital-to-analog conversion side of the equation. This module utilizes two high-performance AD9172 ICs, each offering a remarkable 16-bit resolution and a sample rate of up to 12.6 GSPS. With such capabilities, the FMCP-DAC12P0 can faithfully recreate analog signals from the processed digital data streams generated by the Zynq processor.

Similar to the FMCP-ADC3P0, the FMCP-DAC12P0 also relies on the JESD204B interface for high-speed communication with the Zynq processor. This ensures seamless data flow between the digital processing unit and the DACs, enabling the generation of accurate analog signals that precisely match the digital data.

A Symphony of Technology: Data Acquisition Powerhouse

DataLogger 100's true strength lies in the harmonious interplay of its components. Here's how these elements work together to create a high-speed data acquisition powerhouse:

Data Acquisition Flow:

1. Signal Conditioning (Optional): Depending on the application, the incoming analog signals might require some pre-processing before reaching the ADC. This could involve:
2. High-Speed Analog-to-Digital Conversion (ADC): The heart of the acquisition process lies within the FMCP-ADC3P0 module. Here's what happens:
3. High-Speed Serialization with JESD204B: The raw ADC data needs a high-speed and efficient pathway to reach the Zynq processor. This is where the JESD204B protocol comes into play:
4. Real-Time Processing on the Zynq Processor: The Zynq processor receives the serialized data stream and performs real-time processing tasks:

Data Generation Flow:

1. Digital Signal Processing (DSP) on the Zynq Processor: The Zynq processor takes center stage again, preparing the digital data for conversion back into an analog signal:
2. High-Speed Serialization with JESD204B: Similar to the data acquisition flow, JESD204B facilitates the transmission of the processed digital data to the DAC module:
3. High-Speed Digital-to-Analog Conversion (DAC): The FMCP-DAC12P0 module takes the reins, transforming the digital data back into an analog signal:
4. Digital-to-Analog Conversion: The high-fidelity DACs within the FMCP-DAC12P0 module perform the critical task of converting the received digital data stream back into an analog signal. Each digital value in the data stream is translated into a corresponding voltage level with exceptional precision (16 bits in this case).
5. Analog Filtering (Optional): After the conversion, the analog signal might undergo some post-processing filtering to remove any unwanted high-frequency components introduced during the digital-to-analog conversion process.

Key Considerations:

• Synchronization: Throughout both data acquisition and generation flows, maintaining synchronization between the ADC, Zynq processor, and DAC is crucial. This ensures that all components operate in lockstep, guaranteeing accurate data capture, processing, and reconstruction of the analog signal. The JESD204B protocol incorporates synchronization mechanisms to achieve this seamless coordination.
• Clocking: High-speed data acquisition and generation rely on precise clock signals. The Zynq processor often acts as the master clock source, providing reference clocks to both the FMCP-ADC3P0 and FMCP-DAC12P0 modules. These modules might have additional internal clocking circuitry to further optimize signal integrity and conversion processes.

JESD204B: The Unsung Hero

While the Zynq processor and the FMC+ modules take center stage, the true workhorse behind DataLogger 100's high-speed performance is the JESD204B protocol. This standard provides the critical communication link between the high-speed ADCs and DACs, ensuring:

• Efficiency: Serial data transmission minimizes cable connections and maximizes bandwidth utilization.
