Fairchild Semiconductor introduces the FMS6502, an 8-input, 6-output video switch matrix for consumer and industrial video applications such as automotive in-cabin entertainment systems, HDTVs, flat panel displays and A/V receivers. The FMS6502 integrates analog switch capability, input clamps, bias circuitry and cable drivers into a single device. The device accommodates standard-definition (SD), enhanced-definition (ED) and 1080i/1080p high-definition (HD) video signals and offers selectable 0 and 6dB integrated cable drivers capable of driving dual video loads. The lowest power consuming device of its kind, the FMS6502 further optimizes system power by turning off unused outputs. The FMS6502’s inputs offer a sync-tip clamp or bias option that allows the device to handle video signals with or without sync. The sync-tip clamp option sets the output sync tip level to 300mV (video with sync) and the bias option internally biases the inputs to center signals without sync (Y, Pb, Pr) to 1.25V.
Key features
Switches eight inputs to any of six outputs
Accommodates SD, ED, and 1080i/1080p HD video signals
I2C compatible digital interface Drives 75 Ohm cables directly without the need for external components
Selectable 0 and 6dB integrated cable drivers
Inputs with sync-tip clamp or bias option handle video signals with or with out sync
Ability to disable unused outputs lowers power dissipation
The FMS6502 is available in a compact TSSOP-24 lead (Pb)-free package that meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020C and is compliant with European Union regulations now in effect.
