A dedicated controller for CCD220A dedicated controller for CCD220Some numbers we are not familiar with

– Frame rate : 1500 FPS– Pixel rate : 109Mpixels/s– Data throughput : 218 Mbytes/s (1.7Gb/s)– Parallel transfert rate : 10 Mlines/s– Serial transfert rate : 13.7 MHz– Sequencer resolution below 10ns (100 to 400MHz) – Rise/fall times down to 5ns (70MHz Bandwidth & 4000V/s slew)

– Phases currents : several amps– Phases voltages : up to 50V– And RON : 0.1 electron (with L3 technology)

The fastest astronomical controller ever ?The fastest astronomical controller ever ?

Some numbers we are familiar with :–240x240 pixels & 8 outputs (di piu)
