In addition the driver supports a TRISTATE function that may be used to disable the output stage, thus dropping the device to a low idle power state of 11 mW typical. In addition, the DS90C031 provides power-off high impedance LVDS outputs. This feature assures minimal loading effect on the LVDS bus lines when VCC is not present. The DS90C031 and companion line receiver (DS90C032) provide a new alternative to high power psuedo-ECL devices for high speed pointto-point interface applications. Connection Diagram Figure 1.

Point-to-Point Application APPLICATIONS INFORMATION LVDS drivers and receivers are intended to be primarily used in an uncomplicated point-to-point configuration as is shown in Figure 31. This configuration provides a clean signaling environment for the quick edge rates of the drivers. The receiver is connected to the driver through a balanced media which may be a standard twisted pair cable, a parallel pair cable, or simply PCB traces. Typically, the characteristic impedance of the media is in the range of 100Ω. A termination resistor of 100Ω should be selected to match the media, and is located as close to the receiver input pins as possible. The termination resistor converts the current sourced by the driver into a voltage that is detected by the receiver. Other configurations are possible such as a multi-receiver configuration, but the effects of a mid-stream connector(s), cable stub(s), and other impedance discontinuities as well as ground shifting, noise margin limits, and total termination loading must be taken into account. The DS90C031differential line driver is a balanced current source design. A current mode driver, generally speaking has a high output impedance and supplies a constant current for a range of loads (a voltage mode driver on the other hand supplies a constant voltage for a range of loads). Current is switched through the load in one direction to produce a logic state and in the other direction to produce the other logic state. The typical output current is mere 3.4 mA, a minimum of 2.5 mA, and a maximum of 4.5 mA. The current mode requires (as discussed above) that a resistive termination be employed to terminate the signal and to complete the loop as shown in Figure 31. AC or unterminated configurations are not allowed. The 3.4 mA loop current will develop a differential voltage of 340 mV across the 100Ω termination resistor which the receiver detects with a 240 mV minimum differential noise margin neglecting resistive line losses (driven signal minus receiver threshold (340 mV – 100 mV = 240 mV)). The signal is centered around +1.2V (Driver Offset, VOS) with respect to ground as shown in Figure 32. Note that the steady-state voltage (VSS) peak-to-peak swing is twice the differential voltage (VOD) and is typically 680 mV. The current mode driver provides substantial benefits over voltage mode drivers, such as an RS-422 driver. Its quiescent current remains relatively flat versus switching frequency. Whereas the RS-422 voltage mode driver increases exponentially in most case between 20 MHz–50 MHz. This is due to the overlap current that flows between the rails of the device when the internal gates switch. Whereas the current mode driver switches a fixed current between its output without any substantial overlap current. This is similar to some ECL and PECL devices, but without the heavy static ICC requirements of the ECL/PECL designs. LVDS requires > 80% less current than similar PECL devices. AC specifications for the driver are a tenfold improvement over other existing RS-422 drivers. The TRI-STATE function allows the driver outputs to be disabled, thus obtaining an even lower power state when the transmission of data is not required. The LVDS outputs are high impedance under power-off condition. This allows for multiple or redundant drivers to be used in certain applications. The footprint of the DS90C031 is the same as the industry standard 26LS31 Quad Differential (RS-422) Driver. 12 Submit Documentation Feedback Copyright © 2006–2013, Texas Instruments Incorporated Product Folder Links: DS90C031QML DS90C031QML www.ti.com SNLS202B – MARCH 2006 – REVISED MARCH 2013 Figure 32.
