Product details
Overview
SN65LVDT2DBVT from Texas Instruments is a single-channel LVDS receiver with integrated 110-Ω differential termination, operating from 2.4 V to 3.6 V supply and supporting up to 400 Mbps signaling rates. It features fail-safe open-circuit detection, <100 mV differential input threshold, and LVTTL-compatible output driving logic-level signals in telecom infrastructure and wireless baseband systems.
For engineers reviewing the SN65LVDT2DBVT datasheet, SN65LVDT2DBVT pinout, SN65LVDT2DBVT application, or SN65LVDT2DBVT equivalent, this page delivers verified electrical specs, package mapping, functional role in point-to-point LVDS links, thermal behavior at 85°C, and validated alternative receivers for signal integrity-critical designs.
Technical Context
The SN65LVDT2DBVT implements a fully differential comparator architecture with internal 110-Ω termination across A/B inputs, eliminating external resistors in point-to-point configurations. Its fail-safe circuitry pulls both inputs to VCC via 300-kΩ resistors and forces high output when |VID| < 100 mV - critical for cable-disconnect detection in wireless infrastructure backplanes.
It operates within –40°C to 85°C ambient, draws 4–7 mA supply current, and maintains LVTTL output compliance (VOH ≥ 2.4 V at VCC = 3.0 V, VOL ≤ 0.4 V) while rejecting common-mode noise up to 2.35 V. Input differential resistance is 90–132 Ω, and propagation delay is 1.4–3.6 ns with 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. |
| Max Signaling Rate | 400 Mbps - supports JESD204B subclass 0 links and high-speed serial backplane interconnects. |
| Differential Input Threshold | < ±100 mV - ensures reliable detection of low-amplitude LVDS signals under EMI or trace loss. |
| Integrated Termination | 110 Ω across A/B pins - removes need for external 100 Ω resistor, reducing BOM count and layout area. |
| Fail-Safe Output | High when |VID| < 100 mV - prevents undefined logic states during cable disconnect or driver power-down. |
| Propagation Delay | 1.4–3.6 ns (typ/max) - guarantees sub-4 ns timing budget for synchronous clock/data recovery paths. |
| ESD Rating (Bus Pins) | ±9 kV HBM - protects against handling-induced discharge in automated PCB assembly lines. |
Pinout & Package
SOT-23-5 package (2.90 mm × 1.60 mm), thermally optimized for high-density routing on compact RF modules and baseband boards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC | Power supply input | Must be decoupled with 0.1 µF ceramic capacitor placed ≤2 mm from pin; powers internal termination and output stage. |
| 2 - GND | Ground reference | Low-inductance connection required; ties internal bias networks and ESD protection diodes to system ground plane. |
| 3 - A | Differential non-inverting input | Accepts LVDS+ signal; internally terminated to B via 110 Ω; common-mode range: 0.05 V to VCC − 0.8 V. |
| 4 - B | Differential inverting input | Accepts LVDS− signal; forms matched pair with A; same termination and CMR as Pin 3. |
| 5 - R | LVTTL output | Drives 8 mA sink/source; compatible with 3.3 V FPGA I/O; high-impedance when VCC < 1.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 110 Ω termination | Eliminates external resistor placement error and parasitic inductance, improving impedance matching at 400 Mbps. |
| Fail-safe open-circuit detection | Guarantees high output during cable removal or driver disable - avoids metastability in downstream logic. |
| 5-V tolerant enable not applicable | This is a receiver only; no input tolerance claim applies - inputs are LVDS-only (not LVTTL). |
| VCC-dependent high-impedance mode | Enters Hi-Z state below 1.5 V supply - prevents bus contention during power sequencing in multi-rail systems. |
| Wide common-mode input range | Supports 0.05 V to 2.35 V CMV - accommodates ground shifts up to 1.0 V between transmitter and receiver PCBs. |
Applications
| Wireless Infrastructure Backhaul | Telecom Line Card Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVDS2DBVT | No integrated termination; requires external 100 Ω resistor across A/B inputs. | Better suited for multidrop buses where termination must be placed only at far end. | Select when board layout allows precise 100 Ω placement and system uses multiple receivers on same bus. |
| MAX9107ESA+ | Higher supply current (12 mA typ); no fail-safe; 3.0 V to 3.6 V only. | Used in legacy industrial controllers with fixed 3.3 V rails and no cable hot-swap requirement. | Select only if existing design already uses MAXIM footprint and fail-safe is handled externally. |
Compared with SN65LVDT2DBVT, SN65LVDS2DBVT offers flexible termination placement but increases layout complexity and risk of mismatch, while MAX9107ESA+ lacks fail-safe and consumes >70% more power - making SN65LVDT2DBVT optimal for space-constrained, cable-connected, and safety-aware systems.

FAQ
What is the function of the integrated 110 Ω resistor in SN65LVDT2DBVT?
The integrated 110 Ω resistor in SN65LVDT2DBVT is placed differentially across pins A and B to provide matched termination for LVDS signals, eliminating the need for an external 100 Ω resistor. This improves signal integrity at 400 Mbps by reducing stub inductance and layout sensitivity. The value is optimized for typical PCB trace impedance and accounts for internal device capacitance - confirmed in TI's SLLS373M datasheet Section 8.3.2.5.
Does SN65LVDT2DBVT support fail-safe operation, and how does it behave with open inputs?
Yes, SN65LVDT2DBVT includes fail-safe operation: when differential input voltage |VID| falls below ±100 mV (e.g., due to cable disconnect), internal 300-kΩ pull-up resistors drive both A and B inputs toward VCC, causing the output R to go high. This behavior is guaranteed across –40°C to 85°C and is documented in Section 8.3.2.1 of the SN65LVDT2DBVT datasheet.
What is the maximum signaling rate supported by SN65LVDT2DBVT, and under what conditions?
SN65LVDT2DBVT supports up to 400 Mbps signaling rate, as specified in the "Features" section of its datasheet (SLLS373M). This performance is validated under recommended operating conditions: VCC = 2.4 V to 3.6 V, TA = –40°C to 85°C, and with proper 100 Ω load termination. Switching characteristics in Section 6.8 confirm tPLH/tPHL ≤ 3.6 ns at 400 Mbps.
Can SN65LVDT2DBVT operate with a 2.5 V supply, and what are the output voltage implications?
Yes, SN65LVDT2DBVT operates with a 2.5 V supply per Section 6.3 (Recommended Operating Conditions). At VCC = 2.5 V, VOH is guaranteed ≥ 1.9 V (min) and VOL ≤ 0.4 V (max) under 8 mA load, satisfying LVTTL logic thresholds. Supply current remains within 4–7 mA, and propagation delay increases marginally - all verified in Sections 6.6 and 6.8.
Is SN65LVDT2DBVT pin-compatible with SN65LVDS2DBVT, and what are the key layout differences?
SN65LVDT2DBVT and SN65LVDS2DBVT share identical SOT-23-5 pinout (VCC, GND, A, B, R), but differ functionally: SN65LVDT2DBVT integrates 110 Ω termination across A/B, while SN65LVDS2DBVT requires external 100 Ω. Layout must omit the external resistor for SN65LVDT2DBVT - confirmed in Table 5-2 and Figure 8-3 of the datasheet.
