Product details
Overview
SN65MLVD201DR from Texas Instruments is a multipoint-LVDS (M-LVDS) transceiver IC integrating one driver and one Type-1 receiver in an 8-pin SOIC package. It supports signaling rates up to 200 Mbps, operates from 3.0 V to 3.6 V supply, features ±25 mV input hysteresis, and delivers differential output voltage of 480–650 mV into 50 Ω. It is used in backplane and cabled multipoint data transmission for network switches.
For engineers reviewing the SN65MLVD201DR datasheet, SN65MLVD201DR pinout, SN65MLVD201DR application, or SN65MLVD201DR equivalent, key selection criteria include its M-LVDS compliance (TIA/EIA-899), Type-1 receiver fail-safe behavior, 2.4 ns max propagation delay, –1 V to 3.4 V common-mode input range, and bus-pin high-impedance disable state.
Technical Context
The SN65MLVD201DR implements a true bidirectional M-LVDS transceiver architecture with independent driver enable (DE) and receiver enable (RE) controls. Its driver uses controlled transition times to minimize stub reflections on multipoint buses with loads as low as 30 Ω, while the Type-1 receiver incorporates 25 mV hysteresis to suppress oscillation during slow signal transitions or loss of input.
It meets the TIA/EIA-899 M-LVDS standard - not LVDS (TIA/EIA-644) - and supports operation across –40°C to +85°C. The device maintains stable output common-mode voltage (0.8–1.2 V) and exhibits ≤130 ps peak-to-peak jitter at 200 Mbps with 215–1 PRBS input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Signaling rate | Up to 200 Mbps - enables high-speed backplane clock/data distribution without EMI-intensive single-ended signaling. |
| Differential output voltage | 480–650 mV into 50 Ω - ensures robust noise margin over long stubs and noisy industrial environments. |
| Common-mode input range | –1 V to 3.4 V - tolerates up to 2 V ground potential difference between nodes in distributed systems. |
| Receiver hysteresis | 25 mV (Type-1) - prevents metastability and chatter on slowly rising/falling bus signals or open-circuit conditions. |
| Propagation delay | 1–2.4 ns (driver), 2–6 ns (receiver) - supports tight timing budgets in synchronous multi-drop timing chains. |
| Supply voltage | 3.0–3.6 V - compatible with standard 3.3 V logic domains and industrial power rails. |
| Operating temperature | –40°C to +85°C - qualified for deployment in telecom infrastructure and industrial control cabinets. |
Pinout & Package
SN65MLVD201DR is housed in an 8-pin SOIC (D) package with 1.27 mm pitch, JEDEC MS-012AC compliant, body size 3.91 × 4.90 mm, and thermal pad omitted. Pin functions are validated per TI SLLS558C datasheet Figure 11 and PIN ASSIGNMENTS section.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (R) | Receiver output | CMOS-compatible single-ended logic output; high-impedance when RE = high. |
| 2 (RE) | Receiver enable | Active-low control; disables R output and reduces receiver ICC to ≤4 mA. |
| 3 (DE) | Driver enable | Active-high control; enables A/Y and B/Z outputs; disables them to high-Z when low. |
| 4 (D) | Driver input | Single-ended TTL/CMOS logic input driving differential output pair. |
| 5 (VCC) | Power supply | 3.0–3.6 V supply; decoupling capacitor required within 1 cm for signal integrity. |
| 6 (B) | Bus terminal (in/out) | Inverted differential bus node; connects to twisted-pair backbone or stub. |
| 7 (A) | Bus terminal (in/out) | Non-inverted differential bus node; paired with B for M-LVDS signaling. |
| 8 (GND) | Ground reference | Analog/digital return; must be low-inductance connection to minimize common-mode noise. |
Key Features
| Feature | Design Value |
|---|---|
| M-LVDS standard compliance | Fully conforms to TIA/EIA-899, enabling interoperability with other M-LVDS transceivers in multipoint topologies. |
| Type-1 receiver with hysteresis | 25 mV hysteresis eliminates false triggering on noisy or unterminated bus segments during idle or fault conditions. |
| Glitch-free power-up/down | Driver outputs remain high-impedance until VCC stabilizes - critical for live insertion into active M-LVDS backplanes. |
| Wide common-mode range | –1 V to 3.4 V input tolerance accommodates ground shifts across chassis-mounted modules without level-shifting circuitry. |
| Controlled driver edge rates | Rise/fall times of 1–1.6 ns reduce EMI and improve signal integrity on stubbed transmission lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar M-LVDS transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65MLVD203DR | Same 8-pin SOIC package and Type-1 receiver, but includes internal 120 Ω bus termination resistor; higher ICC (up to 24 mA). | Reduces external component count in point-to-point or short-stub configurations; less suitable for long stubs due to loading. | Select SN65MLVD203DR only if board layout allows direct termination at transceiver and stub lengths are ≤5 cm. |
| SN65MLVD206DR | Same footprint and driver specs, but uses Type-2 receiver with 100 mV offset threshold for open-bus detection. | Provides defined logic state during cable disconnect or driver failure; lacks hysteresis, increasing susceptibility to noise near threshold. | Choose SN65MLVD206DR where failsafe idle-bus reporting is mandatory, such as safety-critical control networks. |
Compared with SN65MLVD203DR and SN65MLVD206DR, the SN65MLVD201DR offers optimal noise immunity via hysteresis without added termination load or offset-induced sensitivity - making it preferred for electrically noisy, long-stub multipoint backplanes requiring stable signal detection.

FAQ
What is the maximum signaling rate supported by the SN65MLVD201DR?
The SN65MLVD201DR supports signaling rates up to 200 Mbps under recommended operating conditions. This performance is verified with 215–1 PRBS input patterns and 50 Ω termination, and is sustained across the full –40°C to +85°C temperature range. The SN65MLVD201DR achieves this rate while maintaining <130 ps peak-to-peak jitter and clean eye diagrams per TI SLLS558C Figure 25–27.
Does the SN65MLVD201DR include built-in bus termination resistors?
No, the SN65MLVD201DR does not integrate bus termination resistors. Unlike the SN65MLVD203DR (which includes a 120 Ω internal termination), the SN65MLVD201DR requires external 50 Ω or 100 Ω differential termination at the bus end(s) to prevent reflections. This design provides flexibility for varying stub lengths and topology configurations in multipoint systems.
How does the Type-1 receiver in the SN65MLVD201DR handle open-circuit bus conditions?
The SN65MLVD201DR's Type-1 receiver has no built-in failsafe bias and relies on external termination or bus biasing to define idle state. With no differential voltage (VID ≈ 0 V), its output becomes indeterminate due to lack of offset threshold - unlike Type-2 receivers (e.g., SN65MLVD206DR). System designers must implement external biasing if deterministic idle-bus detection is required.
What is the common-mode voltage range supported by the SN65MLVD201DR inputs?
The SN65MLVD201DR accepts bus input common-mode voltages from –1 V to 3.4 V. This wide range allows reliable operation despite up to 2 V of ground potential difference between interconnected nodes - a critical capability in large rack-mounted systems or factory-floor installations where ground loops are unavoidable.
Is the SN65MLVD201DR suitable for hot-swap applications?
Yes, the SN65MLVD201DR features glitch-free power-up/down behavior: driver outputs remain in high-impedance state until VCC reaches a valid operating level, preventing bus contention during live insertion. However, the receiver output (R pin) may exhibit a brief glitch during VCC ramp - system firmware should wait for VCC stabilization before sampling R to avoid misreads.
