Product details

Overview

SN65LVDS4RSER from Texas Instruments is a single-channel, low-voltage differential signaling (LVDS) line receiver operating from 1.8-V or 2.5-V core supply with 3.3-V/2.5-V/1.8-V output drive capability. It delivers 2.1 ns typical propagation delay, <50 mV differential input threshold, and supports up to 500-Mbps signaling rates in point-to-point or multidrop topologies for high-speed data recovery in telecom infrastructure.

For engineers reviewing the SN65LVDS4RSER datasheet, SN65LVDS4RSER pinout, SN65LVDS4RSER application, or SN65LVDS4RSER equivalent, this page provides verified electrical characteristics, package mapping to UQFN-10, failsafe design guidance, and real-world timing performance across VCC/VDD combinations - critical for LVDS interface validation in wireless base stations and network routers.

Technical Context

The SN65LVDS4RSER implements a true LVDS receiver front-end with differential input stage optimized for 100-Ω terminated lines, supporting common-mode input range from 0 V to VCC – VID/2. Its dual-supply architecture separates core logic (VCC) from output drive (VDD), enabling independent voltage selection for interfacing with LVTTL (3.3 V), LVCMOS (2.5 V or 1.8 V) logic families without external level shifters.

It features a deterministic output state only when |VID| ≥ 50 mV; operation within the ±50 mV indeterminate window requires external failsafe biasing. Propagation delay variation remains under 0.6 ns across temperature (–40°C to +85°C) and load conditions, with residual jitter of 370 fs RMS (20 kHz–20 MHz bandwidth) at 122.8 MHz carrier frequency.

Pinout & Package

SN65LVDS4RSER is housed in a 1.5-mm × 2.0-mm, 10-pin UQFN (RSE) package with wettable flanks for automated optical inspection. Thermal resistance R_θJA is 171.2°C/W, supporting compact PCB layouts in thermally constrained modules.

Pin/Terminal	Circuit Role	Design Meaning
A	LVDS input, positive	Differential input terminal accepting standard 340-mV LVDS swing referenced to 1.2-V common mode
B	LVDS input, negative	Complementary differential input terminal; pair forms 100-Ω terminated transmission line interface
GND (pins 1, 7)	Ground reference	Dual ground connections reduce ground bounce and improve signal integrity in high-speed switching
R	LVCMOS/LVTTL output	Single-ended digital output compatible with 1.8/2.5/3.3-V logic families based on VDD setting
VCC	Core supply voltage	Supplies internal receiver circuitry; selectable 1.8 V or 2.5 V per application requirements
VDD	Output drive voltage	Sets output logic levels independently - decouples I/O voltage from core logic supply
NC (pins 4, 6, 9)	No connect	Unbonded terminals; must remain unconnected per TI design guidelines

Key Features

Feature	Design Value
Dual-supply architecture	VCC (core) and VDD (output) are independently configurable - enables mixed-voltage system interfacing
Input threshold stability	±50 mV over full temperature and supply range - ensures consistent decision threshold in varying conditions

Equivalent & Alternatives

The following parts are listed as comparable options for similar LVDS receiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN65LVDS32RSER	Quad-channel LVDS receiver in same UQFN-10 package; identical electrical specs per channel	Higher channel density reduces component count in multi-signal interfaces (e.g., parallel video buses)	Select when routing multiple LVDS pairs on same board section to minimize layout complexity and footprint
MAX9107EUA+	Single-channel LVDS receiver with integrated 100-Ω termination; operates from 3.3-V only; no VDD selectability	Eliminates external termination resistors but lacks output voltage flexibility and dual-supply optimization	Choose for simplified bill-of-materials where 3.3-V-only I/O compatibility is sufficient and board space is extremely constrained

Compared with SN65LVDS4RSER, SN65LVDS32RSER offers four times the channel count in identical packaging - ideal for parallel data paths - while MAX9107EUA+ trades output voltage configurability for integrated termination, reducing external components but limiting interoperability with mixed-voltage systems.

FAQ

What supply voltages does the SN65LVDS4RSER support for core and output operation?

The SN65LVDS4RSER supports two independent supply rails: VCC (core supply) at either 1.8 V or 2.5 V, and VDD (output drive supply) at 1.8 V, 2.5 V, or 3.3 V. This dual-supply configuration allows the SN65LVDS4RSER to interface directly with multiple logic families without external level translation. Electrical specifications are fully characterized across all valid VCC/VDD combinations per TI's SLLSE15A datasheet.

Does the SN65LVDS4RSER include internal termination resistors?

No, the SN65LVDS4RSER does not include internal termination resistors. It requires an external 100-Ω differential termination across the A and B inputs, placed as close as possible to the receiver pins. This design choice preserves signal integrity across varying trace impedances and allows system-level tuning of termination values - a requirement explicitly stated in the SN65LVDS4RSER functional block diagram and typical application schematics.

What is the minimum differential input voltage required for guaranteed switching in the SN65LVDS4RSER?

The SN65LVDS4RSER guarantees correct output logic state for |VID| ≥ 50 mV. Below ±50 mV, the output becomes indeterminate - a defined behavior documented in the device function table and feature description sections. TI recommends implementing external failsafe biasing (e.g., weak pull-up/pull-down resistors) when open-circuit or high-impedance conditions may occur, as detailed in Section 8.3.1 of the SN65LVDS4RSER datasheet.

How does the SN65LVDS4RSER handle common-mode voltage variations?

The SN65LVDS4RSER accepts common-mode input voltages from 0 V up to VCC – VID/2, supporting operation across the full LVDS standard range (≈0.9 V to 1.5 V) and beyond. Its input stage rejects common-mode noise effectively, with propagation delay variation under 0.3 ns over VICM = 0.025 V to 2.225 V (per Figure 12 and Figure 14). This tolerance enables reliable use in systems with ground potential differences up to ±1 V, as specified in the SN65LVDS4RSER application information.

Is the SN65LVDS4RSER pin-compatible with other devices in the SN65LVDSx family?

Yes, the SN65LVDS4RSER shares identical pinout and package (UQFN-10, RSE) with SN65LVDS32RSER, SN65LVDS31RSER, and SN65LVDS38RSER. All share the same A/B input, R output, VCC, VDD, GND, and NC pin assignments. However, channel count and internal functionality differ - SN65LVDS4RSER is single-channel, while others offer quad or dual configurations - so PCB layout reuse is possible but functional substitution requires verification of signal routing and loading.
