Notes:
1. Offset and gain errors are removed by enabling the System Monitor automatic gain calibration feature. See Virtex-5 FPGA System Monitor
User Guide.
2. See “System Monitor Timing” in Virtex-5 FPGA System Monitor User Guide.
3. See “Analog Inputs” in Virtex-5 FPGA System Monitor User Guide for a detailed description.
4. Any variation in the reference voltage from the nominal VREFP = 2.5V and VREFN = 0V will result is a deviation from the ideal transfer function.
This also impacts the accuracy of the internal sensor measurements (i.e., temperature and power supply). However, for external ratiometric
type applications allowing the supply voltage and reference to vary by ±2% is permitted.
Performance Characteristics
This section provides the performance characteristics of some common functions and designs implemented in Virtex-5Q
devices. The numbers reported here are worst-case values; they have all been fully characterized. These values are subject
to the same guidelines as the Switching Characteristics. Table 52 shows internal (register-to-register) performance.
