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.
