DESCRIPTION
The DS90LV804 is a four channel 800 Mbps LVDS
buffer/repeater. In many large systems, signals are
distributed across cables and signal integrity is highly
dependent on the data rate, cable type, length, and
the termination scheme.
In order to maximize signal integrity, the DS90LV804
features both an internal input and output (source)
termination to eliminate these extra components from
the board, and to also place the terminations as close
as possible to receiver inputs and driver output. This
is especially significant when driving longer cables.
The DS90LV804, available in the WQFN (Leadless
Leadframe Package) package, minimizes the
footprint, and improves system performance.
An output enable pin is provided, which allows the
user to place the LVDS outputs and internal biasing
generators in a TRI-STATE®, low power mode.
The differential inputs interface to LVDS, and Bus
LVDS signals such as those on TI's 10-, 16-, and 18-
bit Bus LVDS SerDes, as well as CML and LVPECL.
The differential inputs are internally terminated with a
100Ω resistor to improve performance and minimize
board space. This function is especially useful for
boosting signals over lossy cables or point-to-point
backplane configurations.
