8 / 21 page  8 http://www.national.com Pin Descriptions Analog Power VA This is the positive supply pin for the analog supply. It should be connected to a voltage source of +5V and bypassed to AGND with a 0.1µF monolithic capacitor in parallel with a 10µF tantalum capacitor. AGND This is the ground return for the analog sup- ply. Analog I/O OSR, OSG, OSB, Analog Inputs. These inputs (for Red, Green, and Blue) should be tied to the sen- sor’s OS (Output Signal) through DC block- ing capacitors. RefBypass Internally generated reference voltage bypass pin. It should be bypassed to AGND through a .05uF monolithic capacitor. VREF+, VREFMID, VREF- Voltage reference bypass pins. They should each be bypassed to AGND through a .05uF monolithic capacitor. Input & Timing Control MCLK Master Clock. The ADC conversion rate will be a maximum of ¼ of MCLK. Nominally 24MHz. SampCLK Sample Clock. SampCLK controls the con- version rate of the ADC (up to ¼ of the MCLK rate) and sample timing. The signal level is sampled while SampCLK is low and held on the rising edge of SampCLK. When CDS is enabled, the falling edge of SampCLK causes the CCD reference level to be held. If CDS is not enabled, VREF+ or VREF- is held on the falling edge of SampCLK, depending on the programmed signal polarity. SampCLK is also used with NewLine to clamp the exter- nal coupling capacitors. NewLine New Line signal. Used to indicate the start of active pixels on a new line, to allow clamping of the AC coupling caps, and to allow programming of the configuration reg- ister. When NewLine is high and SampCLK is low, the OS inputs will be connected to either VREF+ or VREF-. On the first rising edge of MCLK after NewLine goes low, the internal mux and the offset and gain settings will be set to the appropriate values for the first color of the next line set in the color mode setting in the Sampler and Color Mode Reg- ister. When NewLine is low, D[5-0] transmit the pixel conversion data from the ADC. When NewLine is high, D[5-0] enter TRI- STATE and D2, D1 and D0 act as a serial interface for programming the configuration registers. Digital Power VD This is the positive supply pin for the digital supply. It should be connected to a voltage source of +5V and bypassed to DGND with a 0.1µF monolithic capacitor. DGND This is the ground return for the digital sup- ply. Digital I/O D5 -D0 Data Input/Output pins. When NewLine is low, the 10 or 12 bit conversion results of the ADC are multiplexed to D5-D0. When NewLine is high, the output drivers enter TRI- STATE and D2, D1 & D0 act as a serial inter- face for writing to the configuration regis- ters.

D1 (Latch) Latch and shift enable signal. When D1 (Latch) is low, data is shifted into D0(SDI). When D1(Latch) goes high, the last nine bits shifted into D0(SDI) will be used to program the addressed configuration register. To avoid erroneous writes to the configuration registers, D1(Latch) should be pulled low when NewLine is high. D0 (SDI) Serial input data. Data is valid on D2(SCLK) rising edge. Three address bits followed by six data bits (MSB first) should be shifted into D0 before D1(Latch) goes high. |
