At full 20 Megapixel resolution and with motors, the comprehensive a 12-bit ADC resolution the CMV20000 delivers 30 full frames per package includes one Elliptec second. This is achieved by using 16 LVDS outputs running at 480 MR2K1-06-001 module featur- Mbit/s each. Lower frame rates can be supported by multiplex- ing a high-precision rotatory ing to 8 output channels only. Partial read out, windowing and positioning device capable of subsamples modes, can be programmed to support higher frame registering up to 250.000 steps/ rates. At full resolution and frame rate, the power dissipation is revolution, one Elliptec ML2K1-02-001 module featuring the 1.1W.
