Description
The PI90LV9637 is a differential line receiver that use low-voltage
differential signaling (LVDS) to support data rates in excess of 400
Mbps. These products are designed for applications requiring
high-speed, low-power consumption and low noise generation.
A differential input signal (350mV) is translated by the device to 3V
CMOS output level.
Applications
Applications include point-to-point and multidrop baseband data
transmission over controlled impedance media of approximately
100-ohms. The transmission media can be printed circuit board
traces, backplanes, or cables.
The PI90LV9637provides new alternatives to RS-232, PECL, and
ECL devices for high-speed, point-to-point interface applications.
