STLVDS31B High speed differential line drivers Features Meets or exceeds the requirements of ANSI TIA/EIA-644 standard Low voltage differential signaling with typical output voltage of 350 mV and a 100 load Typical output voltage rise and fall times of 750 ps (400 Mbps) Typical propagation delay times of 1.7 ns TSSOP16 Operates from a single 3.3 V supply Power dissipation 25 mW typical per driver at 200 MHz Driver at high impedance when disabled or with V = 0 V transmission media may be printed circuit board CC traces, backplanes or cables. The ultimate rate Pin compatible with the AM26LS31, and distance of data transfer is dependent upon SN65LVDS31 the attenuation characteristics of the media and Low voltage TTL (LVTTL) logic input levels noise coupling to the environment. The STLVDS31B is characterized for operation Description from - 55 C to 125 C. The STLVDS31B 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 5 V differential standard levels (such as TIA/EIA-422B) to reduce the power, increase the switching speeds and allows operations with a 3.3 V supply rail. Any of the four current mode drivers will deliver a minimum differential output voltage magnitude of 247 mV into a 100 load when enabled. The intended application of this device and signalling technique is for point-to-point baseband data transmission over controlled impedancemedia approximately 100 . The Table 1.
