L2340 L2340 DEVICES INCORPORATED Digital Synthesizer Digital Synthesizer DEVICES INCORPORATED FEATURES DESCRIPTION ❑ Digital Waveform Synthesis at 50 MHz ❑ 24-Bit Polar Phase Angle Accuracy ❑ User-selectable Waveform Synthesis, Frequency Modulation, or Phase Modulation. ❑ Amplitude Input for Amplitude Modulation and Gain Adjustment. ❑ Replaces TRW/Raytheon/Fairchild TMC2340A ❑ 120-pin PQFP The L2340 is a digital synthesizer that performs waveform synthesis, modulation, and demodulation. The L2340 automatically generates quadrature matched pairs of 16-bit sine and cosine waves in DACcompatible 16-bit offset binary format with15-bit amplitude and 32-bit phase inputs. Output waveforms can be phase or frequency modulated. Digital output frequencies are restricted to the Nyquist limit. Functional Description The L2340 converts Polar (Phase and Magnitude) data into Rectangular (Cartesian) coordinates. The user selects the numeric format. A valid transformed result is seen at the output after 22 clock cycles and will continue upon every clock cycle thereafter. 15-bit amplitude and 32-bit phase data are input into the L2340 to produce an output of 16-bit rectangular data. The user may select the data format to either 16-bit offset binary or 15-bit unsigned magnitude format. High accuracy phase increment values with minimal accumulation error is accomplished by use of a 32-bit phase accumulator. The phase accumulator structure supports frequency or phase modulation and is selected by ENP1-0 and accumulator controls FM and PM.

The accuracy of a coordinate transformer is dependent on the word length used for the input variables, the word length used for internal calculations, as well as the number of iterations or steps performed. Truncation errors are due to the finite word length and approximation errors are due to the finite number of iterations. For example, in the case of performing a polar-to-rectangular transformation, the accuracy of the rotation will be determined by how closely the input rotation angle was approximated by the summation of sub-rotation angles. Digital Synthesizer error will introduce noise when performing waveform sythesis, modulation, and demodulation. The minimum theoretical angle resolution that could be produced is 0.00175° when x = 7FFFH and y = 1H. A 16-bit internal processor can produce a minimum angle resolution of only 0.00549° and will not be able to properly calculate the theoretical minimum angle resolution. On the other hand, a 24-bit internal processor can produce a minimum angle resolution of 0.00002° and could therefore properly calculate the theoretical minimum angle resolution. Data values for Figure 2 and Figure 3 are shown in Table 3. By looking at these values, we observe the step resolution on a 16-bit internal processor is not 1 unit in the x and y. In most cases, the minimum step resolution is 2 units in the x and y. On the other hand, step resolution on a 24-bit internal processor is 1 unit in the x and y thus resulting in greater accuracy. FIGURE 2. SOR) CIRCLE TEST RESULT NEAR 45° (16-BIT INTERNAL PROCES23200 23190 23180 In this study, we compare how accurately a coordinate transformer with a 16-bit internal processor versus a 24-bit internal processor can calculate all the coordinates of a circle. By setting the radius to 7FFFH, θ is incremented using the accumulator of the L2340 in steps of 0000 4000H until all the points of a full circle are calculated into rectangular coordinates. The resulting rectangular coordinates were plotted and graphed. A graphical representation of the resulting vectors for both 16-bit and 24-bit internal processors are compared at 45°. Theoretically, a perfect circle is the desired output but when the resulting vectors from a coordinate transformer with 16-bit internal processor are graphed and displayed as shown in Figure 2, we see significant errors due to the inherent properties of a digital synthesizer. In comparison, the 24bit internal processor proves to be significantly more accurate than a 16-bit internal processor due to minimization of truncation errors.

For the tDIS test, the transition is measured to the ±200mV level from the measured steady-state output voltage with ±10mA loads. The balancing voltage, V TH , is set at 3.5 V for Z-to-0 and 0-to-Z tests, and set at 0 V for Zto-1 and 1-to-Z tests. 12. These parameters are only tested at the high temperature extreme, which is the worst case for leakage current. FIGURE A. OUTPUT LOADING CIRCUIT S1 DUT IOL VTH CL IOH FIGURE B.
