Features Single +3.3 V Supply Receiver inputs accept LVDS/CML/LVPECL signals TRI-STATE outputs Receiver input threshold < ±100 mV Fast propagation delay of 1.4 ns (typ) Low jitter 400 Mbps fully differential data path Compatible with BLVDS 10-bit SerDes (40MHz) Compatible with ANSI/TIA/EIA-644-A LVDS standard Available in SOIC and space saving LLP package Industrial Temperature Range Description The DS92001 B/LVDS-BLVDS Buffer takes a BLVDS input signal and provides a BLVDS output signal. In many large systems, signals are distributed across backplanes. One of the limiting factors for system speed is the "stub length" or the distance between the transmission line and the unterminated receivers on individual cards. Although it is generally recognized that this distance should be as short as possible to maximize system performance, real-world packaging concerns often make it difficult to make the stubs as short as the designer would like. The DS92001 has edge transitions optimized for multidrop backplanes where the switching frequency is in the 200 MHz range or less. The output edge rate is critical in some systems where long stubs may be present, and utilizing a slow transition allows for longer stub lengths. The DS92001, available in the LLP (Leadless Leadframe Package) package, will allow the receiver inputs to be placed very close to the main transmission line, thus improving system performance. A wide input dynamic range allows the DS92001 to receive differential signals from LVPECL, CML as well as LVDS sources. This will allow the device to also fill the role of an LVPECL-BLVDS or CML-BLVDS translator.

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.
