Differential Line Driver
Features
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 requiring high-speed, low-power consumption, low-noise generation,
and a small package.
•
•
•
•
•
•
Meets or Exceeds ANSI TIA/EIA-644-1955 Standard
Signaling rates up to 660 Mbps
Bus-Terminal ESD exceeds 2kV
Low-Voltage Differential Signaling with typical Output
Voltages of 350mV:
- 100-ohm load (PI90LV01)
- 50-ohm load (PI90LVB01)
Typical Propagation Delay Times of 1.5ns
Typical Power Dissipation of 20mW @200 MHz
Low-Voltage TTL (LVTTL) Level is 5V Tolerant
Operates from a 3.3V supply
Extended Industrial Temperature Operating Range: –40°C to
105°C
Packaging (Pb-free & Green available):
- 5-pin space-saving SOT23 (T)
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 multipoint (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.
