LVDS Block
The LVDS block is positioned below the data block. It receives a differential clock signal, transmits differential data over the 12 data
channels, and transmits a LVDS clock signal and a synchronization signal over the clock and synchronization channel.
A number of LVDS transmitter blocks are placed in parallel to serve all data, clock, and synchronization output channels. A high level
overview is illustrated in the following figure.
The function of this block is to take 10 bits of the protocol block, serialize these bits, and converts them to an LVDS standard (TIA/EIA
644A) compatible differential output signal. The block must also provide a clock to the host, to allow data recovery. This clock is an
on-chip version of the clock coming from the host.
Sequencer and Logic
The sequencer generates the complete internal timing of the pixel array and the readout. The timing can be controlled by the user
through the SPI register settings. The sequencer operates on the same clock as the data block. This is a division by 10 of the input
clock (internally divided).
