Product details
Overview
PI90LV02ATEX from Diodes Incorporated is a single-channel LVDS high-speed differential line receiver supporting data rates up to 680 Mbps, translating differential LVDS inputs (±350 mV) to 3.3 V CMOS logic outputs with 2.6 ns typical propagation delay, 100 mV differential input threshold, and operation over –40°C to 105°C. It is used in point-to-point baseband data transmission across PCB traces or cables in telecom backplanes.
For engineers reviewing the PI90LV02ATEX datasheet, PI90LV02ATEX pinout, PI90LV02ATEX application, or PI90LV02ATEX equivalent, key selection criteria include differential input voltage threshold (≤100 mV), propagation delay skew (<0.5 ns), 3.3 V supply compatibility, fail-safe open-circuit behavior, and SOT23-5 thermal derating (3.1 mW/°C).
Technical Context
The PI90LV02ATEX implements a current-mode logic (CML)-compatible differential receiver stage with internal termination-independent input structure, enabling direct interface to LVDS and LVPECL sources without external biasing. Its fail-safe design forces high output when inputs are open or shorted, and its 0 V–3.2 V common-mode input range supports wide-swing signaling on lossy media.
Output stage is CMOS-compatible with 2.4 V VOH at –8 mA and 0.4 V VOL at 8 mA, ensuring robust noise margin against 3.3 V LVTTL systems. Power-off input current remains below 20 µA when VCC = 0 V, supporting hot-swap and partial-power-down configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Signaling Rate | Up to 680 Mbps - enables high-throughput serial links in backplane and FPGA interconnects |
| Propagation Delay | 2.1 ns typ. (tPLH/tPHL) - ensures sub-nanosecond timing alignment for multi-lane synchronization |
| Differential Threshold | ±100 mV - guarantees reliable detection of low-amplitude LVDS signals under noise and skew |
| Supply Voltage | 3.0–3.6 V - compatible with standard 3.3 V rail with ±10% tolerance and no level-shifting required |
| Input Common-Mode Range | 0 V to 3.2 V - accommodates DC-coupled and AC-coupled LVDS/LVPECL sources without bias resistors |

Pinout & Package
Package: 5-pin SOT23 (T5), surface-mount, 1.6 mm × 2.8 mm footprint, 1.1 mm height, JEDEC MO-178 compliant, lead-free and green.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC) | Positive supply input | 3.3 V power connection; decoupling capacitor must be placed within 3 mm for stable high-speed operation |
| 2 (GND) | Ground reference | Return path for supply and signal currents; requires low-inductance connection to ground plane |
| 3 (A) | Inverting differential input | Accepts negative leg of LVDS pair; referenced to B for VID = VA – VB calculation |
| 4 (ROUT) | CMOS output | Single-ended 3.3 V logic output; drives standard LVTTL loads with 8 mA sink/source capability |
| 5 (B) | Non-inverting differential input | Accepts positive leg of LVDS pair; differential voltage VID = VA – VB determines output state |
Key Features
| Feature | Design Value |
|---|---|
| Fail-safe open-circuit output | ROUT defaults to logic high when A/B are unconnected or shorted - prevents undefined states in unterminated stubs |
| 5 V-tolerant inputs | LVTTL-level inputs withstand 5 V without damage - simplifies mixed-voltage system integration with legacy controllers |
| Low power at high speed | 85 mW typical @340 MHz - reduces thermal load in dense routing areas and eliminates need for heatsinking |
| High ESD immunity | 2 kV HBM on all pins - meets IEC 61000-4-2 Level 2 for production handling and field reliability |
| Temperature-stable delay | Propagation delay variation <0.4 ns over –40°C to +105°C - maintains timing budget in wide-temperature applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVDS32DR | Higher supply current (12 mA typ.), wider common-mode range (–1 V to 3.4 V), no 5 V-tolerant inputs | Supports negative common-mode voltages (e.g., RS-422), but lacks LVTTL 5 V compatibility | Select when interfacing to legacy industrial transceivers requiring negative input swing |
| MAX9107ESA+ | Slower max rate (400 Mbps), higher propagation delay (3.5 ns), no fail-safe output | Lower cost for non-critical timing applications; requires external pull-up for open-circuit default | Select when budget constraints outweigh timing precision and robustness requirements |
Compared with SN65LVDS32DR and MAX9107ESA+, the PI90LV02ATEX delivers superior timing fidelity (2.1 ns delay, <0.5 ns skew), built-in fail-safe behavior, and 5 V-tolerant inputs-making it optimal for space-constrained, high-reliability LVDS links where deterministic startup and mixed-voltage interoperability are essential.

FAQ
Does PI90LV02ATEX require an external termination resistor?
No. The PI90LV02ATEX does not integrate internal termination and does not require an external 100 Ω resistor across A and B inputs. Its input stage is high-impedance and designed to interface directly with externally terminated LVDS drivers (e.g., PI90LV01A), where termination resides at the driver end or on the PCB.
What is the function of the ROUT pin, and can it drive multiple LVTTL inputs?
ROUT is a CMOS-compatible output delivering 2.4 V high-level and 0.4 V low-level voltages at ±8 mA. It can drive up to three standard 74LVC inputs (each ~20 µA static load) or one 74ACT input (12 mA fanout), provided trace capacitance stays below 5 pF to preserve 680 Mbps signal integrity.
How does the fail-safe feature behave under floating input conditions?
When both A and B inputs are open-circuit or shorted together, the internal comparator forces ROUT to logic high. This is confirmed by the Function Table showing "H" output for |VID| ≤ 50 mV and "Open" condition, preventing undefined states in unterminated or disconnected links.
Is PI90LV02ATEX qualified for automotive AEC-Q100 applications?
No. The PI90LV02ATEX is specified for extended industrial temperature (–40°C to +105°C) but is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., PI90LV02AQ) with PPAP documentation, IATF 16949 manufacturing, and full AEC-Q100 stress testing for automotive use cases.
