5 / 33 page ![]() VV5430 Specifications CD5430F-A 5/33 1. Pixel Clock = CKIN/2 2. Serial Interface clock must be generated by host processor. 1. Digital and Analogue outputs unloaded - add output current. Note: Devices are normaly not 100% tested for the above characterisation parameters, other than Dark Current Signal. Table 6 : Operating characteristics Symbol Parameter Min . Typ. Max. Unit s Note s CKIN EIA Crystal frequency 12.0000 MHz 1 CKIN CCIR Crystal frequency 14.7456 MHz 1 SCL Serial Data Clock 100 KHz 2 Table 4 : AC Operating Conditions Symbol Parameter Min. Typ. Max. Unit s Notes IDCC Digital supply current 10 mA 1 IADD Analog supply current 25 mA 1 IDD Overall supply current 35 mA 1 VREF2V7 Internal voltage reference 2.700 Volts VBG Internal bandgap reference 1.22 Volts VOH Output Voltage Logic “1” 2.4 Volts IOH = 2mA VOL Output Voltage Logic “0” 0.6 Volts IOL = -2mA IILK Input Leakage current -1 µA VIH on input 1 µA VIL on input Table 5 : Electrical Characteristics Typical conditions, VDD = 5.0 V, TA = 27 oC Parameter min. typ. max. units Note Dark Current Signal 50 mV/Sec Modal pixel voltage due to photodiode leakage under zero illumination with Gain=1 (Vdark = (Vt1 - Vt2)/(t1-t2), calculated over two dif- ferent frames Sensitivity 6 V/Lux·Sec VAve/Lux·10ms, where Lux gives 50% saturation with Gain=1 and Exposure=10ms Min. Illumination 0.5 Lux Minimum detectable illumination with Standard CCIR clock |
