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.

Notes:
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.

1. All input pulses are supplied by a generator having the following characteristics: tr or tf
1ns, Pulse Repetition Rate
(PRR) = 50 Mpps, Pulse width = 10 0.2ns. CL includes instrumentation and fixture capacitance within 0.06m of the D.U.T.
2. This point is 1.4V with VCC = 3.3V
3. RL = 100 ohms for PI90LV01 or 50 ohms 1% for PI90LVB01.

NOTE A: All input pulses are supplied by a generator having the following characteristics: tr or tf
1ns, pulse repetition rate (PRR) = 0.5Mpps,
pulse width = 500 10ns. CL includes instrumentation and fixture capacitance within 0.06mm of the D.U.T.
NOTE B: To verify output max signalling rate, the output signal transition time (tr/tf) should not exceed 0.76ns.
