IBIS4-6600
Datasheet
The elementary unit cell is shown in Figure 18. 16 of these cells connected in series,
having a common SPI_CLK form the entire uploadable parameter block, where Dout of
one cell is connected to SPI_DATA of the next cell (max. speed 20 MHz). The
uploaded settings on the address/data bus are loaded into the correct register of the
sensor on the rising edge of signal REG_CLOCK and become effective immediately.
