DS92001  
3.3V B/LVDS-BLVDS Buffer  
General Description  
The LOS pin detects a non-driven B/LVDS bus state at the  
input and provides an active LOW output. The LOS pin can  
be tied to the device’s output enable pin (EN) to generate a  
TRI-STATE output state when the input is un-driven. The  
LOS pin can also be used locally to inform the system of the  
bus state.  
The DS92001 B/LVDS-BLVDS Buffer takes a BLVDS input  
signal and provides an BLVDS output signal. In many large  
systems, signals are distributed across backplanes, and one  
of the limiting factors for system speed is the ’stub length’ or  
the distance between the transmission line and the untermi-  
nated 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 con-  
cerns often make it difficult to make the stubs as short as the  
designer would like.  
Features  
n Single +3.3 V Supply  
n B/LVDS receiver inputs accept LVPECL signals  
n TRI-STATE outputs  
n Loss of Signal (LOS) pin detects a non-driven bus  
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 sys-  
tems where long stubs may be present, and utilizing a slow  
transition allows for longer stub lengths.  
<
n Receiver input threshold  
100 mV  
n Fast propagation delay of 1.4 ns (typ)  
n Low jitter 400 Mbps fully differential data path  
n Compatible with BLVDS 10-bit SerDes (40MHz)  
n Compatible with ANSI/TIA/EIA-644-A LVDS standard  
n Available in SOIC and space saving LLP package  
n Industrial Temperature Range  
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 as well as LVDS sources.  
This will allow the device to also fill the role of an LVPECL-  
BLVDS translator.
