Product details
Overview
DS90LT012AQMF/NOPB from Texas Instruments is an automotive-grade LVDS differential line receiver in a 5-pin SOT-23 package, supporting >400 Mbps data rates (200 MHz), featuring integrated 100 Ω input termination, 3.3 V single-supply operation, and AEC-Q100 Grade 1 qualification for use in infotainment display links and camera sensor interfaces.
For engineers reviewing the DS90LT012AQMF/NOPB datasheet, DS90LT012AQMF/NOPB pinout, DS90LT012AQMF/NOPB application, or DS90LT012AQMF/NOPB equivalent, key selection criteria include fail-safe biasing capability (−100 mV to 0 V threshold), differential skew ≤100 ps (typ), propagation delay ≤3.5 ns, and compatibility with ANSI/TIA/EIA-644-A LVDS standard in harsh-temperature automotive environments.
Technical Context
The DS90LT012AQMF/NOPB implements a CMOS-based LVDS receiver architecture with internal 100 Ω differential termination, enabling point-to-point interconnects without external resistors. It accepts LVDS, CML, and LVPECL input signals and translates them to 3 V CMOS output levels with rail-to-rail swing.
Its fail-safe design guarantees TTL HIGH output under open-circuit, shorted, or terminated conditions, and its enhanced threshold region (−100 mV to 0 V) supports robust noise margin with minimal external biasing-e.g., +25 mV bias yields 55 mV differential noise margin versus standard ±100 mV receivers requiring +125 mV bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | >400 Mbps (200 MHz) - enables high-resolution video pixel clock recovery in automotive displays |
| Propagation Delay | ≤3.5 ns max - ensures timing alignment in synchronous parallel LVDS links |
| Differential Skew | ≤100 ps typical - maintains signal integrity across fast edge transitions |
| Supply Voltage | +3.0 V to +3.6 V - compatible with standard 3.3 V automotive power rails |
| Operating Temp | −40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood and cabin modules |
| Input Termination | Integrated 100 Ω resistor - eliminates need for external termination, reducing BOM count and PCB area |
| ESD Rating | HBM >8 kV - provides robust handling during automotive assembly and service |
Pinout & Package
SOT-23 (DBV) 5-pin package: 1.45 mm max height, 2.9 mm × 1.6 mm footprint, lead-free (Sn) finish, MSL Level-1, RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Power supply input | Accepts +3.3 V ±0.3 V; requires local 0.1 µF + 0.001 µF ceramic decoupling |
| 2 - GND | Ground reference | Return path for supply and signal currents; must be low-impedance connection to system ground plane |
| 3 - IN+ | Non-inverting LVDS input | Accepts differential input with common-mode range 0.1 V to 2.35 V; optimized for 0 V to +2.4 V operation |
| 4 - IN− | Inverting LVDS input | Paired with IN+; differential input voltage (IN+ − IN−) ≥0 V produces TTL HIGH output |
| 5 - TTL OUT | CMOS-compatible output | 3 V logic-level output driving 15 pF load; VOH ≥2.4 V at −0.4 mA, VOL ≤0.5 V at 2 mA |
Key Features
| Feature | Design Value |
|---|---|
| Fail-Safe Output Logic | Guarantees TTL HIGH output on open/short/terminated inputs - eliminates need for external bias networks in unpowered or disconnected states |
| Enhanced Threshold Region | −100 mV to 0 V switching window - improves noise margin with low-value external bias (e.g., +25 mV yields 55 mV DNM) |
| Low Power Dissipation | 9 mA typical no-load supply current - enables use in thermally constrained automotive ECUs without forced cooling |
| LVDS/CML/LVPECL Compatibility | Accepts multiple differential signaling standards - simplifies integration with diverse SerDes sources including image sensors and FPGAs |
| Power-Down High-Z Inputs | LVDS inputs enter high-impedance state when VDD = 0 V - prevents back-driving of upstream drivers during power sequencing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9107EUT+T | 5-pin SOT-23, 3.3 V supply, but rated only to +85°C ambient; no AEC-Q100 qualification | Limited to non-automotive industrial or consumer video links; lacks fail-safe open-circuit behavior | Select only for cost-sensitive commercial designs where temperature and reliability requirements are relaxed |
| SN65LVDS1 | SOIC-8 package, higher supply current (14 mA typ), no integrated termination resistor | Requires external 100 Ω termination; larger footprint unsuitable for space-constrained automotive modules | Choose when board layout allows SOIC placement and external termination is preferred for impedance tuning flexibility |

The DS90LT012AQMF/NOPB operates from −40°C to +125°C and is qualified to AEC-Q100 Grade 1 standards, making it suitable for under-hood and cabin-mounted automotive electronics where extreme thermal cycling occurs. This range is validated per TI's recommended operating conditions and absolute maximum ratings tables in the SNLS297E datasheet.
Does the DS90LT012AQMF/NOPB require external termination resistors?
No, the DS90LT012AQMF/NOPB integrates a 100 Ω differential termination resistor optimized for point-to-point LVDS applications. This eliminates the need for external termination components, reduces PCB area, and simplifies layout-confirmed by TI's functional diagram, truth table, and "Integrated Line Termination Resistor" feature listing in the datasheet.
How does the fail-safe functionality of the DS90LT012AQMF/NOPB work?
The DS90LT012AQMF/NOPB guarantees a TTL HIGH output when inputs are open, shorted, or properly terminated-due to its internal fail-safe circuitry and enhanced −100 mV to 0 V threshold region. As shown in the truth table and application notes, this behavior prevents undefined states during cable disconnection or driver power loss, ensuring robust system-level fault tolerance.
Can the DS90LT012AQMF/NOPB accept non-LVDS differential inputs?
Yes, the DS90LT012AQMF/NOPB accepts LVDS, CML, and LVPECL input signals per its datasheet specification. Its input stage is designed for wide common-mode range (0.1 V to 2.35 V) and differential sensitivity down to 100 mV, enabling interoperability with multiple high-speed signaling standards used in automotive image sensors and FPGAs.
What is the maximum data rate supported by the DS90LT012AQMF/NOPB?
The DS90LT012AQMF/NOPB supports data rates exceeding 400 Mbps (200 MHz), verified by TI's switching characteristics table and fMAX specification of 250 MHz under defined test conditions (tr/tf < 1 ns, 15 pF load).
