NCS6415
Bus−Controlled Video
Matrix Switch
Description
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.
All switching possibilities are controlled through the I2C bus.
Features
• Cascadable with another NCS6415 (Internal Address can be changed
by Pin 7 Voltage)
• 8 Inputs (CVBS, RGB, Chroma, ...)
• 6 Outputs with Low Impedance Driver
• Possibility of Chroma Signal for each Input by Switching off the
Clamp with an External Resistor Bridge
• Bus Controlled
• 6.5 dB Gain between any Input and Output
• −45 dB Crosstalk at 5 MHz
• Compatible with TEA6415C
• Full ESD Protection
• These are Pb−Free Devices
