Product details
Overview
DS90C401MX/NOPB from Texas Instruments is a dual-channel LVDS driver IC designed for high-speed point-to-point serial data transmission in embedded display and industrial interface systems. It delivers 340 mV typical differential output swing, operates at ≥155.5 Mbps, complies with TIA/EIA-644 standard, and draws only 3.0 mA no-load supply current at +5 V. It serves as the transmit-side driver paired with DS90C402 receiver in low-power, noise-immune digital links.
For engineers reviewing the DS90C401MX/NOPB datasheet, DS90C401MX/NOPB pinout, DS90C401MX/NOPB application, or DS90C401MX/NOPB equivalent, this page provides verified technical context, real-world design meaning of key specs, SOIC-8 package layout, functional alternatives, and supply support for volume deployment in timing-critical interconnects.
Technical Context
The DS90C401MX/NOPB implements a current-mode differential driver architecture with two independent channels, each sourcing ±3.4 mA into a 100 Ω termination to generate 340 mV differential voltage. Its fixed-current switching eliminates overlap current, enabling flat power consumption across frequency - unlike voltage-mode drivers whose ICC rises exponentially above 20 MHz.
Each channel features matched propagation delay (tPHLD/tPLHD ≤ 3.5 ns), low skew (tSK1 ≤ 1.0 ns channel-to-channel, tSK2 ≤ 3.0 ns chip-to-chip), and TTL/CMOS-compatible inputs driving LVDS-compliant outputs. The device requires external 100 Ω termination at the receiver end and does not support AC-coupled or unterminated configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Differential Output Swing | 250–450 mV (typ. 340 mV): Enables robust noise margin >240 mV when terminated into 100 Ω, meeting LVDS receiver threshold requirements. |
| Max Data Rate | ≥155.5 Mbps: Supports high-resolution video pixel clocking and fast control bus signaling without signal integrity degradation. | Supply Current (No Load) | 1.7–3.0 mA (at VCC = 5.0 V): Ultra-low static power enables use in thermally constrained or battery-backed systems. |
| Propagation Delay | 0.5–3.5 ns (per channel): Ensures sub-nanosecond timing alignment critical for synchronous parallel-to-serial conversion interfaces. |
| Channel Skew | ≤1.0 ns (channel-to-channel): Maintains inter-pair timing integrity for dual-lane applications like RGB666 display links. |
| Input Logic Compatibility | TTL/CMOS (VIH ≥ 2.0 V, VIL ≤ 0.8 V): Directly interfaces with FPGA I/O banks and microcontroller GPIO without level-shifting. |
| Operating Temperature | −40°C to +85°C: Qualified for industrial-grade operation in factory automation and outdoor display enclosures. |
Pinout & Package
DS90C401MX/NOPB uses an 8-pin SOIC (Package D) with 1.27 mm pitch, 3.91 mm body width, and 1.75 mm max height - compatible with standard surface-mount assembly processes and IPC-7351 land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | +5.0 V ±10% power supply input; decoupling capacitor required within 10 mm for stable high-frequency operation. |
| 2, 6 | DOUT− | Inverting LVDS output per channel; must be routed as controlled-impedance differential pair (Z₀ ≈ 100 Ω). |
| 3, 7 | DOUT+ | Non-inverting LVDS output per channel; paired with adjacent DOUT− for balanced EMI suppression. |
| 4, 8 | DIN | TTL/CMOS logic input per channel; accepts 0–5 V swing; no internal pull-up/down; requires clean edge rates. |
| 5 | GND | Analog/digital ground reference; must connect to low-impedance PCB plane adjacent to VCC decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Current-mode driver topology | Delivers constant 3.4 mA loop current regardless of frequency - eliminates exponential ICC rise seen in RS-422 voltage-mode drivers. |
| TIA/EIA-644 compliance | Guarantees interoperability with industry-standard LVDS receivers (e.g., DS90C402, SN65LVDS1) without signal conditioning. |
| Low EMI emission | 340 mV differential swing and tightly matched edge rates (tTLH/tTHL ≤ 2.0 ns) reduce radiated emissions in dense PCB layouts. |
| ESD protection | HBM ≥3500 V ensures handling robustness during SMT assembly and board-level test without conductive foam. |
| SOIC-8 footprint | Enables drop-in replacement in legacy designs using 8-pin SO packages; supports automated optical inspection (AOI) and reflow profiling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVDS1DR | Single-channel, 3.3 V supply only, 400 mV min VOD, higher ICC (8 mA typ) | Requires separate devices for dual-channel needs; better suited for 3.3 V systems with tighter noise margins | Select when migrating to 3.3 V logic domains or needing higher VOD headroom |
| DS90LV011ATM/NOPB | Single-channel, 3.3 V supply, 350 mV typ VOD, 2.5 ns max tPD, SOIC-8 | Lower power (1.8 mA ICC) but lacks dual integration; identical pinout per channel | Choose for cost-sensitive single-lane links where board space permits two units |
Compared with DS90C401MX/NOPB, SN65LVDS1DR offers higher noise immunity at 3.3 V but doubles component count for dual lanes, while DS90LV011ATM/NOPB reduces power by 40% yet requires duplicated layout and routing - making DS90C401MX/NOPB optimal for compact, 5 V, dual-channel LVDS interconnects.

FAQ
What is the recommended termination for DS90C401MX/NOPB?
The DS90C401MX/NOPB requires a 100 Ω differential termination resistor placed as close as possible to the receiver input pins. This resistor converts the 3.4 mA constant output current into the specified 340 mV differential voltage swing. AC coupling or unterminated configurations are not supported and will cause signal integrity failure.
Does DS90C401MX/NOPB support 3.3 V operation?
No. DS90C401MX/NOPB is specified only for +4.5 V to +5.5 V supply operation (typ. +5.0 V). Its input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and output offset voltage (VOS = 1.25 V typ) are optimized for 5 V logic domains. For 3.3 V systems, consider DS90LV011ATM/NOPB or SN65LVDS1DR instead.
Can DS90C401MX/NOPB drive multiple receivers in a multidrop configuration?
No. DS90C401MX/NOPB is designed strictly for point-to-point topologies per TIA/EIA-644. Multidrop configurations introduce impedance discontinuities, stub reflections, and degraded noise margin - all uncharacterized and unsupported. Use dedicated bus LVDS transceivers (e.g., SN65LVDS31) for multidrop applications.
What is the thermal performance limit of DS90C401MX/NOPB?
DS90C401MX/NOPB has a maximum junction temperature of +150°C and a thermal derating of 8.5 mW/°C above +25°C in its SOIC-8 package. At full load (14.0 mA ICC), power dissipation remains below 100 mW - well within the 1068 mW max rating at +25°C - ensuring reliable operation without heatsinking in ambient temperatures up to +85°C.
Is DS90C401MX/NOPB pin-compatible with DS90C401M/NOPB?
Yes. DS90C401MX/NOPB and DS90C401M/NOPB share identical SOIC-8 (Package D) mechanical dimensions, pinout, electrical specifications, and thermal characteristics. The only difference is packaging: MX/NOPB ships in 2500-unit tape-and-reel, while M/NOPB uses 95-unit tubes - both are functionally and electrically interchangeable.
