Bus-controlled switch matrix enhances video fidelity

The ON Semiconductor NCS6416 is a video switch matrix optimised for low output impedance, high output current and high linearity, to achieve video switching comparable to studio-quality signals.

The NCS6416 features an 8-input, 6-output switch matrix, which allows any single input to be connected to several outputs. Each output may be switched to only one of the inputs. In addition each input can be used as a normal input, or as a chroma input if used with an external resistor bridge. The switching configuration is controlled via the I²C interface provided, which allows high-speed control of video routing using an external controller. Each new configuration is implemented across the I²C bus by communicating only the changed output channels, to minimise bus traffic and ensure fast switching.

An external Programming pin allows two devices to be operated in parallel and selected independently through the I²C bus. This allows designers to double the signal capacity of a single NCS6416, or to cascade two devices for extra flexibility.
