FMS6502: Video Switch Matrix with Output Drivers
The FMS6502 provides eight inputs that can be routed to any of six outputs. Each input can be routed to one or more outputs, but only one input may be routed to any output.
Each input supports an integrated clamp option to set the output sync tip level of video with sync to ~300mV. Alter- natively, the input may be internally biased to center out- put signals without sync (Chroma, Pb, Pr) at ~1.25V.
All outputs are designed to drive a 150Ω DC-coupled load. Each output can be programmed to provide either 0dB or 6dB of signal gain.
Input-to-output routing and input bias mode functions are controlled via an I2C-compatible digital interface.
Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera- ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi- tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
PCB Thermal Layout Considerations
• Understand the system power requirements and envi- ronmental conditions.
• Maximize thermal performance of the PCB.
• Consider using 70μm of copper for high-power designs.
