INTRODUCTION UT54LVDS031 Quad Driver quad CMOS differential line driver designed applications requiring ultra power dissipation high data rates. device designed support data rates excess 155.5 Mbps (77.7 MHz) utilizing Voltage Differential Signaling (LVDS) technology. UT54LVDS031 accepts input levels translates them voltage (340mV) differential output signals. addition, driver supports three-state function that used disable output stage, disabling load current, thus dropping device ultra idle power state. UT54LVDS031 companion quad line receiver UT54LVDS032 provide alternatives high power pseudoECL devices high speed point-to-point interface applications.

APPLICATIONS INFORMATION UT54LVDS031 driver's intended primarily uncomplicated point-to-point configuration shown Figure This configuration provides clean signaling environment quick edge rates drivers. receiver connected driver through balanced media such standard twisted pair cable, parallel pair cable, simply traces. Typically, characteristic impedance media range 100. termination resistor should selected match media located close receiver input pins possible. termination resistor converts current sourced driver into voltages that detected receiver. Other configurations possible such multireceiver configuration, effects mid-stream connector(s), cable stub(s), other impedance discontinuities, well ground shifting, noise margin limits, total termination loading must taken into account.

current mode driver provides substantial benefits over voltage mode drivers, such RS-422 driver. quiescent current remains relatively flat versus switching frequency. Whereas RS-422 voltage mode driver increases exponentially most cases between MHz. This overlap current that flows between rails device when internal gates switch. Whereas current mode driver switches fixed current between output without substantial overlap current. This similar some PECL devices, without heavy static requirements ECL/PECL design. LVDS requires less current than similar PECL devices. specifications driver tenfold improvement over other existing RS-422 drivers. Three-State function allows driver outputs disabled, thus obtaining even lower power state when transmission data required.
