Description
The PI90LV02 and PI90LVT02 are single differential line receivers
that use low-voltage differential signaling (LVDS) to support data
rates up to 400 Mbps. These products are designed for applications
requiring high-speed, low-power consumption, low-noise genera-
tion, and a small package.
A differential input signal (350mV) is translated by the device to a
3.3V CMOS output level. The PI90LVT02 integrates the terminating
resistor while the PI90LV02 requires an external resistor.
Applications
Applications include point-to-point and multi-drop baseband data
transmissions over impedance media of approximately 100-ohms.
The transmission media can be printed circuit board traces,
backplanes, or cables.
The PI90LV02 and PI90LVT02 and companion line drivers (PI90LV01
and PI90LVB01) provide new alternatives to RS-232, PECL, and ECL
devices for high-speed, point-to-point interface applications.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated under "Recommended Operating Conditions" is not implied. Exposure to Absolute-
Maximum-Rated conditions for extended periods may affect device reliability.
