Diodes Incorporated PI90LV01ATEX

Overview

PI90LV01ATEX from Diodes Incorporated is a 3.3V, SOT23-5 LVDS differential line driver compliant with ANSI TIA/EIA-644, supporting signaling rates up to 660 Mbps, delivering 350 mV typical differential output voltage into 100 Ω, and featuring 1.5 ns typical propagation delay. It serves as a high-speed interface transmitter in point-to-point and multi-point baseband data links over PCB traces or cables.

For engineers reviewing the PI90LV01ATEX datasheet, PI90LV01ATEX pinout, PI90LV01ATEX application, or PI90LV01ATEX equivalent, key selection criteria include LVDS compliance, 3.3V supply operation, sub-2ns propagation delay, 2kV HBM ESD rating, and SOT23-5 space-constrained packaging for high-density routing.

Technical Context

The PI90LV01ATEX translates LVTTL/CMOS input logic (5V-tolerant) into low-voltage differential signals using current-mode logic architecture, maintaining signal integrity at 660 Mbps across controlled-impedance media. Its output stage delivers tightly matched rise/fall times (0.6–1.5 ns) and <0.3 ns pulse skew to preserve timing margins in high-speed serial links.

Designed for robust noise immunity, it supports ≥1 V ground potential difference between transmitter and receiver while meeting TIA/EIA-644 minimum differential output magnitude (247 mV) and steady-state common-mode voltage (1.125–1.375 V), enabling reliable operation in electrically noisy industrial environments.

FAQ

What is the recommended termination for PI90LV01ATEX outputs?

The PI90LV01ATEX differential outputs (Y and Z) require a 100 Ω termination resistor placed across them at the receiver end. This resistor may be split into two 50 Ω resistors tied to a common 1.25 V bias (V_CC/2) for DC-coupled operation, or AC-coupled with a single 100 Ω resistor to ground if common-mode voltage matching is handled by the receiver. The device itself does not integrate termination.

Can PI90LV01ATEX operate with a 2.5V supply?

No. The absolute maximum supply voltage is 4.0 V, but the recommended operating range is strictly 3.0–3.6 V per the datasheet. Operation below 3.0 V violates the specified minimum V_CC, resulting in undefined output voltage swing, increased propagation delay, and potential failure to meet TIA/EIA-644 differential output magnitude requirements (247 mV min).

Does PI90LV01ATEX support hot-swap or power-off isolation?

Yes. When V_CC = 0 V, the outputs enter high-impedance state with ≤±1 µA power-off output current, preventing back-driving of downstream receivers. This feature allows safe insertion/removal in live backplane systems and supports partial power-down modes in modular industrial controllers without requiring external isolation switches.

How does the 5V-tolerant DIN input function internally?

The DIN input uses a clamped input structure with internal series resistance and ESD diodes referenced to V_CC, allowing safe operation up to 6 V even when V_CC = 3.3 V. Logic thresholds remain fixed at VIH ≥ 2.0 V and VIL ≤ 0.8 V, ensuring compatibility with 5V CMOS outputs without external level translation, while drawing only 2–20 µA input current across the full valid input range.
