Description
PI90LV387/ PI90LVB387 consists of sixteen differential line
drivers that implement the electrical characteristics of low-volt-
age differential signaling (LVDS). This signaling technique lowers
output voltage levels to reduce power, increase switching speeds,
and allow operation with a 3V supply rail.
The intended application of this device and signaling technique
is for point-to-point baseband (single termination) and multi-
point (double termination) data transmission over a controlled
impedance media of approximately 100 and 50 (LVB387).
The transmission media may be printed-circuit board traces, back-
planes, or cables. The large number of drivers integrated into the
same substrate, with the low pulse skew of balanced signaling,
allows extremely precise timing alignment of clock and data for
synchronous parallel data transfers. When used with its companion
16-channel receivers, the PI90LV386 or PI90LVT386, over 400
million data transfers per second in single-edge clocked systems
are possible with very little power.
(Note: The ultimate rate and distance of data transfer is dependent
upon attenuation characteristics of the media, the noise coupling
to the environment, and other system characteristics.)
The drivers are enabled in groups of five. When disabled, driver
outputs are at a high impedance. Each driver input (D
IN
) and en-
able (EN) have an internal pulldown that drives the input to a low
level when open circuited.
The parts are characterized for operation from –40°C to 85°C.
