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 LCD clock (PCLK).

DESCRIPTION (CONTINUED) 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. This minimizes power consumption without the need for controlling an external pin. The SN65LVDS301 is characterized for operation over ambient air temperatures of –40°C to 85°C. All CMOS inputs offer failsafe features to protect them from damage during power-up and to avoid current flow into the device inputs during power-up. An input voltage of up to 2.165 V can be applied to all CMOS inputs while V is DD between0Vand1.65V.

Shutdown Mode The SN65LVDS301 enters Shutdown mode when the TXEN pin is asserted low. This turns off all transmitter circuitry, including the CMOS input, PLL, serializer, and SubLVDS transmitter output stage. All outputs are high- impedance.CurrentconsumptioninShutdownmodeisnearlyzero. Standby Mode The SN65LVDS301 enters the Standby mode if TXEN is high and the PCLK input signal frequency is less than 500kHz. All circuitry except the PCLK input monitor is shut down, and all outputs enter high-impedance mode. The current consumption in Standby mode is very low. When the PCLK input signal is completely stopped, the I currentconsumptionislessthan10μA.ThePCLKinputmustnotbeleftfloating. DD NOTE A floating (left open) CMOS input allows leakage currents to flow from V to GND. To DD prevent large leakage current, a CMOS gate must be kept at a valid logic level, either V IH or V . This can be achieved by applying an external voltage of V or V to all IL IH IL SN65LVDS301inputs. 8 SubmitDocumentationFeedback Copyright©2006–2012,TexasInstrumentsIncorporated ProductFolderLinks:SN65LVDS301
SN65LVDS301 www.ti.com SLLS681D–FEBRUARY2006–REVISEDAUGUST2012 Active Modes When TXEN is high and the PCLK input clock signal is faster than 3 MHz, the SN65LVDS301 enters Active mode. Current consumption in Active mode depends on operating frequency and the number of data transitions inthedatapayload. Acquire Mode (PLL approaches lock) The PLL is enabled and attempts to lock to the input Clock. All outputs remain in high-impedance mode. When the PLL monitor detects stable PLL operation, the device switches from Acquire to Transmit mode. For proper device operation, the pixel clock frequency must fall within the valid f range specified under recommended PCLK operating conditions. If the pixel clock frequency is larger than 3 MHz but smaller than f (min), the PCLK SN65LVDS301 PLL is enabled. Under such conditions, it is possible for the PLL to lock temporarily to the pixel clock,causingthePLLmonitortoreleasethedeviceintotransmitmode.Ifthishappens,thePLLmayormaynot be properly locked to the pixel clock input, potentially causing data errors, frequency oscillation, and PLL deadlock(lossofVCOoscillation). Transmit Mode After the PLL achieves lock, the device enters the normal transmit mode. The CLK pin outputs a copy of PCLK. Based on the selected mode of operation, the D0, D1, and D2 outputs carry the serialized data. In 1-channel mode,outputsD1andD2remainhigh-impedance.Inthe2-channelmode,outputD2remainshigh-impedance. Parity Bit Generation The SN65LVDS301 transmitter calculates the parity of the transmit data word and sets the parity bit accordingly. The parity bit covers the 27 bit data payload consisting of 24 bits of pixel data plus VS, HS and DE. The two reserved bits are not included in the parity generation. ODD Parity bit signaling is used. The transmitter sets the Parity bit if the sum of the 27 data bits result in an even number of ones. The Parity bit is cleared otherwise. This allowsthereceivertoverifyParityanddetectsinglebiterrors.

SN65LVDS301 SLLS681D–FEBRUARY2006–REVISEDAUGUST2012 www.ti.com APPLICATION INFORMATION Preventing Increased Leakage Currents in Control Inputs A floating (left open) CMOS input allows leakage currents to flow from V to GND. Do not leave any CMOS DD Input unconnected or floating. Every input must be connected to a valid logic level V or V while power is IH OL suppliedtoV .Thisalsominimizesthepowerconsumptionofstandbyandpowerdownmode. DD Power Supply Design Recommendation For a multilayer pcb, it is recommended to keep one common GND layer underneath the device and connect all groundterminalsdirectlytothisplane. Decoupling Recommendation The SN65LVDS301 was designed to operate reliably in a constricted environment with other digital switching ICs. In many designs, the SN65LVDS301 often shares a power supply with the application processor. The SN65LVDS301 can operate with power supply noise as specified in Recommend Device Operating Conditions. To minimize the power supply noise floor, provide good decoupling near the SN65LVDS301 power pins. The use of four ceramic capacitors (2×0.01 μF and 2×0.1 μF) provides good performance. At the very least, it is recommended to install one 0.1 μF and one 0.01 μF capacitor near the SN65LVDS301. To avoid large current loops and trace inductance, the trace length between decoupling capacitor and IC power inputs pins must be minimized.PlacingthecapacitorunderneaththeSN65LVDS301onthebottomofthepcbisoftenagoodchoice. VGA Application Figure 38 shows a possible implementation of a VGA display. The LVDS301 interfaces to the SN65LVDS302, which is the corresponding receiver device to deserialize the data and drive the display driver. The pixel clock rate of 22 MHz assumes ~10% blanking overhead and 60 Hz display refresh rate. The application assumes 24- bit color resolution. It is also shown, how the application processor provides a powerdown (reset) signal for both serializer and the display driver. The signal count over the FPC could be further decreased by using the standby optionontheSN65LVDS302andpullingRXENhighwitha30kΩ resistortoV .
