SN65LVDS30x -可编程 27 位显示屏串行接口发送器

The SN65LVDS301 serializer device converts 27 parallel data inputs to 1, 2, or 3 Sub Low-Voltage Differential Signaling (SubLVDS) serial outputs. It loads a shift register with 24 pixel bits and 3 control bits from the parallel CMOS input interface. In addition to the 27 data bits, the device adds a parity bit and two reserved bits into a 30-bit data word. Each word is latched into the device by the pixel clock (PCLK). The parity bit (odd parity) allows a receiver to detect single bit errors. The serial shift register is uploaded at 30, 15, or 10 times the pixel-clock data rate depending on the number of serial links used. A copy of the pixel clock is output on a separate differential output.
