5.8.2.2. Bus LVDS I/O Standard in Intel® Cyclone® 10 LP Devices
The Intel® Cyclone® 10 LP top, bottom, and right side I/O banks support the Bus LVDS I/O standard. For the Bus LVDS transmitter, Intel® Cyclone® 10 LP devices use emulated differential output. For the Bus LVDS receiver, Intel® Cyclone® 10 LP devices use the true LVDS input buffer. The transmitter and receiver share the same pins. Intel® Cyclone® 10 LP devices require an output enable (OE) signal to tristate the output buffers when the LVDS input buffer receives a signal.
- The termination resistor (RT) must match the bus differential impedance, which in turn depends on the loading on the bus. Increasing the load decreases the bus differential impedance.
- With termination at both ends of the bus, termination is not required between the two signals at the input buffer.
- Bus LVDS requires a single series resistor (RS) at the output buffer to match the impedance to the transmission line. The series resistor affects the voltage swing at the input buffer.
- The maximum data rate achievable depends on many factors.
