DS92001
3.3V B/LVDS-BLVDS Buffer
General 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 recog-
nized that this distance should be as short as possible to
maximize system performance, real-world packaging con-
cerns 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 transi-
tion 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 sys-
tem 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.
