視頻處理-ZL6502，8輸入6輸出視頻，仙童FMS6502 深圳市威步科技有限公司主打產品，功能是：8輸入，6輸出視頻切換距降和輸出驅動，輸入夾，輸出夾，偏壓電路；并能兼容仙童品牌的FMS6502； The ZL6502 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. Alternatively， the input may be internally biased to center output 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.
