Description
The PI90LV01 and PI90LVB01 are differential line drivers that use
low-voltage differential signaling (LVDS) to support data rates up
to 660 Mbps. These products are designed for applications requir-
ing high-speed, low-power consumption, low-noise generation,
and a small package.
The TIA/EIA-644 standard compliant electrical interface provides
a minimum differential output voltage magnitude of 247mV into
a 100- ohm load and receipt of 100mV signals with up to 1V of ground
potential difference between a transmitter and receiver. The
PI90LVB01 doubles the output drive current to achieve LVDS levels
with a 50-ohm load.
A low-voltage TTL/CMOS input level is translated by the device
into a low-voltage (350mV) differential output signal.
Applications
Applications include point-to-point (single termination) and multi-
point (double termination) baseband data transmissions over
controlled impedance media . The transmission media can be printed
circuit board traces, backplanes, or cables.
The PI90LV01 and companion line receivers (PI90LV02 and
PI90LVT02) provide new alternatives to RS-232, PECL and ECL
devices for high-speed, point-to-point interface applications.
