2.1
VV5410/VV6410 is a CIF format CMOS image sensor. The VV5410 sensor is the basic monochrome device and VV6410 is the
colourised variant. The operation of VV5410 and VV6410 is very similar but any differences will be identified and explained.
VV6410 can output digital colourised pixel data at frame and line rates compatible with either NTSC or PAL video standards.
VV5410 and VV6410 contain the same basic video timing modes. Table 2 summarises these video modes.
The various operating modes are detailed in Section 3.
Important: VV5410 and VV6410’s output video data stream only contains raw data. A master co-processor is required to
generate a video waveform that can be displayed on a VDU
Note: The user can also provide a 24 MHz clock, rather than a 16 MHz clock, for the QCIF-60fps, CIF-25fps and CIF-30fps
modes, which the sensor then internally divides by 1.5, (see data_format[22]), to give an effective input clock frequency of 16
MHz.
2.2
VV5410/VV6410 does not include any form of automatic exposure and/or gain control. Thus to produce a correctly exposed
image the integration period for the pixels, in the sensor array, an exposure control algorithm must be implemented externally.
The new exposure values are written to the sensor via the serial interface.
2.3
The sensor’s offers a very flexible digital interface, the main components of which are listed below:
1. A tri-stateable 5-wire data bus (D[4:0]) for sending both video data and embedded timing references.
2. 4-wire and 8-wire data bus alternatives available. If the 8-wire option is selected then the FST/LST pins are reconfigured to
3. A data qualification clock, QCK, which can be programmable via the serial interface to behave in a number of different ways
4. A line start signal, LST (Tri-stateable).
5. A frame start signal, FST (Tri-stateable).
6. OEB tri-states all 5 data bus lines, D[4:0], the qualification clock, QCK, LST, FST and D[7].
7. A 2-wire serial interface (SDA,SCL) for controlling and setting up the device.
