Frequently Asked Questions
What is the maximum data rate of SN75LVDS391PWG4 per channel and how does this affect system throughput?
Each of the 4 channels supports up to 630 Mbit/s, giving a total aggregate throughput of 2.52 Gbit/s across all channels. This performance level is sufficient for high-speed parallel bus interfaces, camera link connections, and FPGA inter-board communication links requiring low-latency data transfer at 3.3 V supply.
Which interface standard does SN75LVDS391PWG4 comply with and what does this mean for signal integrity?
The device complies with EIA-644 and TIA-644 LVDS standards, which specify 350 mV differential output swing and 1.2 V common-mode voltage. This standardization ensures interoperability with any TIA-644-compliant LVDS receiver, and the low-swing differential signaling minimizes radiated EMI compared to CMOS or TTL single-ended interfaces at equivalent data rates.
How does SN75LVDS391PWG4 benefit a design transmitting parallel sensor data over 1-meter cable runs?
LVDS differential signaling used by SN75LVDS391PWG4 provides inherent common-mode noise rejection across cable runs up to several meters. At 630 Mbit/s per channel over a 100-ohm differential pair, the signal integrity remains robust against ground-plane noise and cable-induced common-mode interference that would corrupt single-ended CMOS signals at the same data rate.
Can SN75LVDS391PWG4 interface directly with an FPGA's LVDS input banks without additional components?
Yes. SN75LVDS391PWG4 outputs are TIA-644-compliant with 350 mV differential swing centered around 1.2 V common-mode, matching the LVDS input specifications of most FPGAs operating from a 3.3 V or 2.5 V I/O supply. A 100-ohm differential termination resistor at the receiver input is required, but no level-shifting or additional active components are needed.
