Features • 1.5 Gbps data rate per channel • Configurable pre-emphasis drives lossy backplanes and cables • Low output skew and jitter • LVDS/CML/LVPECL compatible input, LVDS output • On-chip 100Ω input and output termination • 12 kV ESD protection on LVDS outputs • Single 3.3V supply • Very low power consumption • Industrial -40 to +85°C temperature range • Small TQFP Package Footprint • Evaluation Kit Available • See SCAN90004 for JTAG-enabled version Description The DS90LV004 is a four channel 1.5 Gbps LVDS buffer/repeater. High speed data paths and flow-through pinout minimize internal device jitter and simplify board layout, while configurable pre-emphasis overcomes ISI jitter effects from lossy backplanes and cables. The differential inputs interface to LVDS, and Bus LVDS signals such as those on National's 10-, 16-, and 18- bit Bus LVDS SerDes, as well as CML and LVPECL. The differential inputs and outputs are internally terminated with a 100Ω resistor to improve performance and minimize board space. The repeater function is especially useful for boosting signals for longer distance transmission over lossy cables and backplanes.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
