Frame rate with analog output
Up to 23 full frames per second (see table1.1)
Table 1.1: In this table you find achievable values using the analog output
Note 1. The pixel rate can be boosted to 37.5 MHz. This requires a few measures.
• increase the analog bandwidth by halving the resistor on pin Nbias_oamp
• increase the ADC speed by the resistors related to the ADC speed (nbiasana1, nbiasana2, pbiasencload)
• experimentally fine tune the relative occurrence of the ADC clock relative to the X-pixel clock.
Note 2. The pure digital scan speed in X and Y direction is roughly 50 MHz. This is the maximum speed for skipping rows and
columns.
