1/13 may 2003 n meets or exceeds the requirements of ansi tia/eia-644 standard n low voltage differential signaling with typical output voltage of 350mv and a 100 w load n typical output voltage rise and fall times of 750ps (400mbps) n typical propagation delay times of 1.7ns n operates from a single 3.3v supply n power dissipation 25mw typical per driver at 200mhz n driver at high impedance when disabledorwithv cc =0v n pin compatible with the am26ls31, sn65lvd31 n low voltage ttl (lvttl) logic input levels description the STLVDS31 is a quad differential line drivers that implements the electrical characteristics of low voltage differential signaling (lvds). this signaling technique lowers the output voltage levels of 5v differential standard levels (such as tia/eia-422b) to reduce the power, increase the switching speeds and allows operations with a 3.3v supply rail. any of the four current mode drivers will deliver a minimum differential output voltage magnitude of 247mv into a 100 w load when enabled. the intended application of this device and signalling technique is for point-to-point baseband data transmission over controlled impedance media approximately 100 w . the transmission media may be printed circuit board traces, backplanes or cables. the ultimate rate and distance of data transfer is dependent upon the attenuation characteristics of the media and noise coupling to the environment. the STLVDS31 is characterized for operation from -40c to 85c. ordering codes typ e temperature range package comments STLVDS31bd -40 to 85 c so-16 (tube) 50parts per tube / 20tube per box STLVDS31bdr -40 to 85 c so-16 (tape & reel) 2500 parts per reel STLVDS31btr -40 to 85 c tssop16 (tape & reel) 2500 parts per reel STLVDS31 high speed differential line drivers sop tssop
