Frequently Asked Questions
How is the differential signal swing level controlled?
The Swing Level (SL) pin controls it: High reduces the swing to 200mV, while low or open maintains a normal 350mV swing.
What voltage standard must be used for operation?
This IC uses a 3.3V power supply and is specified as being interoperable with existing 5V LVDS receivers.
When is the driver functionally enabled or disabled?
The driver is enabled when the Enable pin (EN) is high, and it is disabled when EN is low or open.
