Product details
Overview
SN65LVDT2DBVR from Texas Instruments is a single-channel LVDS receiver with integrated 110-Ω differential input termination, operating from 2.4 V to 3.6 V supply. It delivers 2.4 V LVTTL output at 3 V supply, supports up to 400 Mbps signaling, features open-circuit fail-safe, and maintains <100 mV differential input threshold. It is used in high-speed point-to-point interconnects within wireless infrastructure baseband modules.
For engineers reviewing the SN65LVDT2DBVR datasheet, SN65LVDT2DBVR pinout, SN65LVDT2DBVR application, or SN65LVDT2DBVR equivalent, key selection criteria include integrated termination compatibility, fail-safe behavior under open inputs, 400 Mbps receiver bandwidth, LVTTL output drive strength, and SOT-23 thermal performance at elevated ambient temperatures.
Technical Context
The SN65LVDT2DBVR implements a differential comparator architecture with internal 110-Ω termination across A/B inputs, eliminating external resistors in point-to-point topologies. Its fail-safe circuitry pulls both inputs to VCC via 300-kΩ resistors and forces high-level output when |VID| < 100 mV.
It operates as a level translator: LVDS differential input (±100 mV threshold, 0.05–2.45 V common-mode range) to single-ended LVTTL output (VOH ≥ 2.4 V @ IOH = –8 mA, VOL ≤ 0.4 V @ IOL = 8 mA), with propagation delay of 2.5 ns typical and pulse skew < 0.6 ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.4 V to 3.6 V - enables direct interface with 2.5 V/3.3 V FPGA I/O banks without level shifters. |
| Differential Input Threshold | < ±100 mV - ensures reliable detection of low-amplitude LVDS signals even with PCB trace loss. |
| Receiver Propagation Delay | 2.5 ns typical - supports timing-critical clock/data recovery in sub-2.5 ns setup windows. |
| Integrated Termination | 110 Ω across A/B inputs - replaces external 100 Ω resistor, reduces BOM count and layout area. |
| LVTTL Output Drive | VOH ≥ 2.4 V @ –8 mA, VOL ≤ 0.4 V @ 8 mA - directly drives standard 3.3 V logic inputs without buffering. |
| Fail-Safe Behavior | Output forced high when |VID| < 100 mV and inputs open - prevents undefined logic states during cable disconnect or driver disable. |
| ESD Rating (Bus Pins) | ±9 kV HBM - protects against handling and system-level ESD events in telecom equipment assembly. |
Pinout & Package
SOT-23-5 package (2.90 mm × 1.60 mm body size) with exposed pad for thermal enhancement; 5-pin configuration optimized for minimal PCB footprint in space-constrained RF front-end modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply input | Must be decoupled locally with 0.1 µF ceramic capacitor; powers internal termination and output stage. |
| GND | Ground reference | Low-inductance connection required; ties internal bias networks and ESD protection clamps. |
| A | Differential non-inverting input | Accepts LVDS signal; internally terminated to B via 110 Ω; common-mode range 0.05–2.45 V. |
| B | Differential inverting input | Paired with A; forms differential pair with integrated 110 Ω termination; same common-mode limits. |
| R | LVTTL output | Single-ended CMOS-compatible output; high-impedance when VCC < 1.5 V; drives 3.3 V logic loads directly. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 110 Ω termination | Eliminates external resistor placement and routing, reducing signal path discontinuities and board area by ~12 mm². |
| Open-circuit fail-safe | Guarantees high output state during cable removal or upstream driver shutdown-no external pull-up needed. |
| 5-V tolerant disable control not applicable | VCC-dependent high-impedance mode below 1.5 V enables safe power sequencing without external enable logic. |
| Low propagation delay variation | Pulse skew ≤ 0.6 ns ensures <10 ps jitter contribution in 400 Mbps data links, critical for eye diagram integrity. |
| Wide common-mode input range | Supports 0.05 V to 2.45 V at 3.3 V supply-accommodates ground shifts up to ±350 mV between driver/receiver PCBs. |
Applications
| Wireless Baseband Processing | Telecom Line Card Interconnect |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVDS2DBVR | No integrated termination; requires external 100 Ω resistor across A/B inputs; identical pinout and LVTTL output specs. | Suitable for multidrop buses where termination must be placed only at far end; adds 1.2 mm² layout area and two vias. | Select when system topology demands discrete termination placement or when cost sensitivity outweighs BOM simplification. |
| MAX9121ESA+ | Higher supply range (3.0–5.5 V); no fail-safe; 3.5 ns propagation delay; SO-8 package only. | Used in legacy 5 V systems; lacks open-circuit protection; incompatible with 2.4 V operation or SOT-23 space constraints. | Choose only if existing 5 V design mandates pin-compatible upgrade and fail-safe is handled externally. |
Compared with SN65LVDS2DBVR, SN65LVDT2DBVR reduces component count and improves signal fidelity in point-to-point links but restricts use in multidrop configurations. Against MAX9121ESA+, it enables lower-voltage operation and embedded fail-safe-critical for battery-powered and safety-critical medical imaging systems.

FAQ
What is the function of the integrated 110 Ω termination in SN65LVDT2DBVR?
The integrated 110 Ω termination across pins A and B replaces an external 100 Ω resistor, matching typical LVDS transmission line impedance to minimize reflections. This simplifies layout, reduces parasitic inductance from discrete components, and ensures consistent signal integrity in point-to-point links-key for reliable operation of SN65LVDT2DBVR in 400 Mbps applications.
Does SN65LVDT2DBVR support operation at 2.4 V supply voltage?
Yes, SN65LVDT2DBVR is fully specified from 2.4 V to 3.6 V. At 2.4 V, it maintains LVTTL-compatible output levels (VOH ≥ 1.9 V, VOL ≤ 0.4 V), 400 Mbps capability, and fail-safe functionality. This makes SN65LVDT2DBVR suitable for battery-backed or low-power subsystems where rail voltage may dip near minimum specification.
How does the open-circuit fail-safe work in SN65LVDT2DBVR?
When differential input voltage |VID| falls below ±100 mV-such as during cable disconnect or upstream driver disable-SN65LVDT2DBVR pulls both A and B inputs to VCC via internal 300-kΩ resistors and forces the R output high. This deterministic state prevents metastability in downstream logic and eliminates need for external fail-safe circuitry, a core reliability feature of SN65LVDT2DBVR.
Can SN65LVDT2DBVR be used in multidrop bus topologies?
SN65LVDT2DBVR is not recommended for all nodes in a multidrop bus. Its integrated 110 Ω termination loads the bus at each receiver location, distorting characteristic impedance and causing signal reflections. It may be used only at the far end of a multidrop line-as the sole termination point-or in point-to-point configurations. For multidrop, SN65LVDS2DBVR with external end-of-line termination is preferred.
What is the maximum signaling rate supported by SN65LVDT2DBVR?
SN65LVDT2DBVR supports receiver operation up to 400 Mbps, as confirmed in TI's SLLS373M datasheet. This rate is validated across the full –40°C to +85°C temperature range and 2.4–3.6 V supply range. Signal integrity at this speed relies on controlled-impedance PCB routing, proper termination, and adherence to recommended layout guidelines for SN65LVDT2DBVR.
