7.3.8 Test Pattern

The ADC32RF5x provides two different options to output test patterns instead of the actual output data of the ADC to simplify the serial interface and system debug of the JESD204B digital interface link. The output data path is shown in Figure 7-41.

GUID-18D3BD32-2734-44BB-BA10-0669F8127060-low.gifFigure 7-41 Test Pattern Options

The available test patterns in each block are described in Table 7-44. Both test pattern blocks replace output data from the digital block (and not from the ADC) and therefore are available in decimation or decimation bypass mode. The test patterns are synchronized with the SYSREF signal.

The RAMP pattern provides two different output options. Internally each ADC data bus consists of parallel data streams. The RAMP pattern is generated for each stream and a different starting value can be set for each stream. By default all starting values are 0 and increment =1. For example, DDC bypass mode uses 4 internal data streams per ADC channel. Enabling a RAMP pattern would show a 'slow' ramp which increments once every 4 clock cycles with starting values set to 0 and ramp increment = 1.

On other hand a RAMP pattern which increments every clock cycle can be set using different starting values (e.g. 0/1/2/3) for the 4 streams and setting the RAMP increment to 4. Table Table 7-45 shows the register addresses for the different digital streams being used for each operating mode.
