Frequently Asked Questions
What are the key specifications of the SN65LVDS391PWRG4?
The SN65LVDS391PWRG4 is a quad LVDS line driver with four independent differential output channels compliant with EIA-644 and TIA-644 LVDS standards. It supports high data rates suitable for transmission above 400 Mbps per channel with low EMI characteristics. The maximum input current is 20 µA, and the device is packaged in a 16-pin TSSOP format. The G4 suffix confirms RoHS lead-free compliance.
What is LVDS and why is it used for high-speed data interfaces?
LVDS (Low Voltage Differential Signaling) is a high-speed, low-power electrical signaling standard that transmits data as a differential voltage between two conductors rather than as a single-ended voltage referenced to ground. The differential nature provides excellent noise immunity since common-mode interference is rejected at the receiver. LVDS achieves high data rates with low power consumption and minimal EMI, making it the preferred interface standard for backplane links, camera interfaces, flat panel display connections, and other high-speed embedded system communications.
What interface standards does the SN65LVDS391PWRG4 comply with?
The SN65LVDS391PWRG4 complies with both EIA-644 (Electronic Industries Alliance) and TIA-644 (Telecommunications Industry Association) LVDS standards, which define the electrical characteristics of LVDS drivers and receivers. Compliance with these standards ensures interoperability with any compliant LVDS receiver from any manufacturer, provided the system meets signal integrity requirements. The EIA-644/TIA-644 standard specifies differential output voltage, common-mode range, and driver impedance to ensure reliable operation.
What package does the SN65LVDS391PWRG4 use and what does the suffix indicate?
The SN65LVDS391PWRG4 is housed in a 16-pin TSSOP (Thin Shrink Small Outline Package), designated JESD-30 code R-PDSO-G16. The 'PW' in the part number refers to the TSSOP package, 'R' indicates tape-and-reel packaging for SMT assembly, and 'G4' confirms RoHS compliance (lead-free). The TSSOP package offers a compact footprint with fine pitch leads, suitable for high-density PCB designs in space-constrained applications.
What are alternative LVDS quad transmitters compatible with the SN65LVDS391PWRG4?
Compatible LVDS quad line drivers include Texas Instruments' own SN75LVDS391 (5 V tolerant variant) and other EIA-644 compliant quad transmitters from manufacturers such as Maxim Integrated (DS90LV047A series), ON Semiconductor (MC100LVELT22), and Renesas. When selecting an alternative, designers should verify compliance with EIA-644/TIA-644, differential output voltage levels, data rate capability, propagation delay, and package pinout to ensure signal integrity and board compatibility.
