PI90LVB022LE

Overview

The PI90LVB022LE is a Low Voltage Differential Signaling (LVDS) multiplexer and repeater manufactured by Diodes Incorporated. It integrates two differential line drivers and receivers capable of signaling rates up to 650 Mbit/s. The device operates from a single 3.3V supply within an industrial temperature range of -40°C to +85°C. It features Bus LVDS signaling with doubled output drive current for 50 Ohm loads, TTL-compatible inputs, and fail-safe input protection. The component is available in 16-pin SOIC and TSSOP packages.

Feature Summary

• Multiplexing capability allows flexible signal routing between two channels using control signals S0 and S1.
• Bus LVDS architecture doubles output drive current to support multi-point configurations on 50 Ohm loads.
• Inputs are designed to be open, short, and terminated fail-safe with high impedance states when disabled.

Applications

• Multipoint data transmissions over controlled impedance media
• Signal routing and cross-point switching functions
• Splitter applications for distributing LVDS signals

Procurement Notes

Verify the specific package variant required, as the LE suffix indicates a TSSOP-16 housing. Confirm that the design supports Bus LVDS requirements for 50 Ohm termination, distinguishing it from standard point-to-point LVDS variants. Ensure the system voltage aligns with the specified 3.3V operating range.

Selection Notes

Select this component when multipoint connectivity or signal routing is required within an LVDS network. The PI90LVB022LE is distinct from the PI90LV022 due to its enhanced drive current for 50 Ohm loads. Verify that the application utilizes a 3.3V power supply and requires TTL-level input compatibility for control signals.

Part Context

This part belongs to the PI90LV022 family of LVDS interface devices. While the base PI90LV022 handles point-to-point connections with 100 Ohm loads, the PI90LVB022 variant specifically addresses Bus LVDS standards. The 'LE' designation identifies the physical packaging as a 16-pin Thin Shrink Small Outline Package (TSSOP).

Replacement Considerations

The PI90LV022LE serves as a functional alternative for point-to-point applications requiring 100 Ohm loads instead of Bus LVDS. Other members of the PI90LV022 series may offer different packaging options such as SOIC-16.
