As shown in the section describing the basic operation of the LTC1821, the output voltage of the DAC circuit is directly affected by the voltage reference; thus, any voltage reference error will appear as a DAC output voltage error.There are three primary error sources to consider when selecting a precision voltage reference for 16-bit applica-tions: output voltage initial tolerance, output voltage tem-perature coefficient (TC), and output voltage noise.Initial reference output voltage tolerance, if uncorrected,generates a full-scale error term. Choosing a reference with low output voltage initial tolerance, like the LT1236(±0.05%), minimizes the gain error due to the reference;however, a calibration sequence that corrects for system zero- and full-scale error is always recommended.A reference’s output voltage temperature coefficient af-fects not only the full-scale error, but can also affect the circuit’s INL and DNL performance. If a reference is chosen with a loose output voltage temperature coeffi-cient, then the DAC output voltage along its transfer characteristic will be very dependent on ambient condi-tions. Minimizing the error due to reference temperature coefficient can be achieved by choosing a precision refer-ence with a low output voltage temperature coefficient and/or tightly controlling the ambient temperature of the circuit to minimize temperature gradients.As precision DAC applications move to 16-bit and higher performance, reference output voltage noise may contrib-ute a dominant share of the system’s noise floor. This in turn can degrade system dynamic range and signal-to-noise ratio. Care should be exercised in selecting a voltageTable 2.

Precision voltage refer-ences, like the LT1236, produce low output noise in the 0.1Hz to 10Hz region, well below the 16-bit LSB level in 5V or 10V full-scale systems. However, as the circuit band-widths increase, filtering the output of the reference may be required to minimize output noise.GroundingAs with any high resolution converter, clean grounding is important. A low impedance analog ground plane and star grounding should be used. AGNDF and AGNDS must be tied to the star ground with as low a resistance as possible.When it is not possible to locate star ground close to AGNDF and AGNDS, separate traces should be used to route these pins to the star ground. This minimizes the voltage drop from these pins to ground due to the code dependent current flowing into the ground plane. If the resistance of these separate circuit board traces exceeds 1Ω, the circuit of Figure␣3 eliminates this code dependent voltage drop error for high resistance traces.To calculate PC track resistance in squares, divide the length of the PC track by the width and multiply this result by the sheet resistance of copper foil. For 1 oz copper (≈1.4 mils thick), the sheet resistance is 0.045Ω per square.1314Information furnished by Linear Technology Corporation is believed to be accurate and reliable.

Chapter 3Product SpecificationThe DMA/Bridge Subsystem for PCI Express® (PCIe®) in conjunction with the Integrated Block for PCI Express IP, provides a highly configurable DMA Subsystem for PCIe, and a highperformance DMA solution.StandardsThe DMA/Bridge Subsystem for PCIe is compliant with the following specifications:•AMBA AXI4-Stream Protocol Specification (ARM IHI 0051A)•PCI Express Base Specification v2.1 and v3.0Performance and Resource UtilizationFor DMA Perfomance data, see AR 68049.For DMA Resource Utilization, see Resource Utilization web page.Minimum Device RequirementsThe following table lists the link widths and supported speed for a given speed grade.PG195 (v4.1) April 29, 2021DMA/Bridge Subsystem for PCIe v4.1Chapter 2OverviewThe DMA/Bridge Subsystem for PCI Express® (PCIe®) can be configured to be either a high-performance direct memory access (DMA) data mover or a bridge between the PCI Express and AXI memory spaces.•DMA Data Mover: As a DMA, the core can be configured with either an AXI (memory mapped) interface or with an AXI streaming interface to allow for direct connection to RTLlogic. Either interface can be used for high performance block data movement between thePCIe address space and the AXI address space using the provided character driver. In additionto the basic DMA functionality, the DMA supports up to four upstream and downstreamchannels, the ability for PCIe traffic to bypass the DMA engine (Host DMA Bypass), and anoptional descriptor bypass to manage descriptors from the FPGA fabric for applications thatdemand the highest performance and lowest latency.•Bridge Between PCIe and AXI Memory: When configured as a PCIe Bridge, received PCIe packets are converted to AXI traffic and received AXI traffic is converted to PCIe traffic. Thebridge functionality is ideal for AXI peripherals needing a quick and easy way to access a PCIExpress subsystem. The bridge functionality can be used as either an Endpoint or as a RootPort. PCIe Bridge functionality is only supported for UltraScale+™ devices. Non UltraScale+devices have specific a PCIe Bridge IP available in the Vivado® IP catalog. For details aboutPCIe Bridge mode operation, see AXI Bridge for PCI Express Gen3 Subsystem Product Guide(PG194).This document covers DMA mode operation only.PG195 (v4.1) April 29, 2021DMA/Bridge Subsystem for PCIe v4.1。
