The main function of the NCS6415 is to switch 8 video
input sources to the 6 outputs.
Each output can be switched to only one of the inputs,
whereas any single input may be connected to several
outputs. The lowest level of each signal is aligned on each
input (bottom of sync pulse for CVBS or Black Level for
RGB signals).
The nominal gain between any input and output is 6 dB.
For Chroma signals, the alignment is switched off by
forcing, with an external 5‘ VDC resistor bridge on the input.
Each input can be used as a normal input or as a Chroma
input (with external resistor bridge). All the switching
possibilities are changed through the I2C bus.
The switches configuration is defined by words of 16 bits:
one word of 16 bits for each output channel.
So, 6 words of 16 bits are necessary to determine the
starting configuration upon poweron (power supply: 0 to
10 V). But a new configuration needs only the words of the
changed output channels. Driving a 75
W load requires an
external transistor.
