SIS3300 8 Channel 100 MHz 12-bit ADC


The SIS3300 is an 8 channel 6U VME digitizer/transient recorder with a sampling rate of up to 105 MHz (for the individual channel) and 12-bit resolution. The board has a width of one VME slot (4TE). The boards multi event and dual memory bank functionality make the card the choice for many demanding digitizer applications.

The SIS3301 65/80/105 MHz 14-bit FADC is the second member of this board family.

Trapezoidal FIR filter for triggering (major firmware revision 0x11)

A trapezoidal filter was implemented for DC/offset independent trigger generation. The screen shot below shows the input on ADC channel 1 and the corresponding FIR filtered data (which can be stored to ADC memory in test mode also).
