This clock is applied at N times the input pixel rate (N = 2, 3, 6, 8 or any multiple of 2 thereafter depending on input sample mode). 5 DGND Supply Digital ground (0V). 6 SEN Digital input Enables the serial interface when high. 7 DVDD2 Supply Digital supply (5V/3.3V), all digital I/O pins. 8 SDI Digital input Serial data input. 9 SCK Digital input Serial clock. Digital multiplexed output data bus. ADC output data (d11:d0) is available in 4-bit multiplexed format as shown below. AB C D 10 OP[0] Digital output d8 d4 d0 OVRNG 11 OP[1] Digital output d9 d5 d1 CC0 12 OP[2] Digital output d10 d6 d2 CC1 13 OP[3]/SDO Digital output d11 d7 d3 0 Alternatively, pin OP[3]/SDO may be used to output register read-back data when address bit 4=1 and SEN has been pulsed high. See Serial Interface description in Device Description section for further details. 14 AVDD Supply Analogue supply (5V) 15 AGND1 Supply Analogue ground (0V). 16 VRB Analogue output Lower reference voltage. This pin must be connected to AGND via a decoupling capacitor. 17 VRT Analogue output Upper reference voltage. This pin must be connected to AGND via a decoupling capacitor. 18 VRX Analogue output Input return bias voltage. This pin must be connected to AGND via a decoupling capacitor. 19 VRLC/VBIAS Analogue I/O Selectable analogue output voltage for RLC or single-ended bias reference. This pin would typically be connected to AGND via a decoupling capacitor. VRLC can be externally driven if programmed Hi-Z. 20 VINP Analogue input Video input. |
