The SN65LVDS301 is a serialising device where the input paralle data is converted to Sub Low-Voltage Differential Signaling (SubLVDS) serial outputs. The SN65LVDS301 supports three power modes (Shutdown, Standby and Active) to conserve power. When transmitting, the PLL locks to the incoming pixel clock PCLK and generates an internal high-speed clock at the line rate of the data lines. The parallel data are latched on the rising or falling edge of PCLK as selected by the external control signal CPOL. The serialized data is presented on the serial outputs D0, D1, D2 with a recreated PCLK generated from the internal high-speed clock, output on the CLK output. If PCLK stops, the device enters a standby mode to conserve power

The parallel (CMOS) input bus offers a bus-swap feature. The SWAP pin configures the input order of the pixel data to be either R[7:0]. G[7:0], B[7:0], VS, HS, DE or B[0:7]. G[0:7], R[0:7], VS, HS, DE. This gives a PCB designer the flexibility to better match the bus to the host controller pinout or to put the transmitter device on the top side or the bottom side of the PCB.

Two Link Select lines LS0 and LS1 control whether 1, 2 or 3 serial links are used. The TXEN input may be used to put the SN65LVDS301 in a shutdown mode. The SN65LVDS301 enters an active Standby mode if the input clock PCLK stops.
