This Player one cam has much higher full well and FPS than Zwo ASI version: this is even faster than read mode 0F at full resolution was it due to over-clocking as in personal computers? Speculation: by slightly over-voltaging the CMOS chip, so that the chip can run in slightly higher clock rate. But data is still output within the required spec. Of course the the extra heat needs to be properly dissipated, eg active cooling using IMX323 for illustration below: the analog voltages, VDDH 1000 FPS kickstarter PAM4 demodulation Multi slope ADC MTK imagiq APU Paddle lite AliExpress Poseidon pro IMX571
