PI90LVB022WE

Overview

The PI90LVB022WE is a Low Voltage Differential Signaling (LVDS) multiplexer and repeater manufactured by Diodes Incorporated. It operates from a 3.3V supply within an industrial temperature range of -40°C to +85°C. The device supports signaling rates up to 650 Mbit/s with a typical propagation delay of 3.5ns. It features two differential receivers and drivers, utilizing S0 and S1 control signals for routing. The 'B' variant provides doubled output drive current for Bus LVDS signaling into a 50 Ohm load, compared to the standard 100 Ohm load requirement. Inputs are TTL compatible and fail-safe.

Feature Summary

• Multiplexing capability allows flexible signal routing between two differential inputs and outputs via control pins.
• Bus LVDS architecture doubles output drive current to support multi-point configurations on 50 Ohm loads.
• Fail-safe input design ensures defined states during open, shorted, or unterminated conditions.
• High impedance output state activates when disabled or when supply voltage drops below 1.5V.

Applications

• Multipoint data transmission over controlled impedance media
• Signal routing and cross-point switching in high-speed digital systems
• LVDS bus line driver applications requiring dual termination

Procurement Notes

Verify the specific suffix 'W' against the manufacturer's ordering guide to confirm the package type, as datasheets list SOIC and TSSOP options. Confirm RoHS compliance status through official documentation before integration. Ensure the design accounts for the 16-pin footprint dimensions provided in the mechanical drawings.

Selection Notes

Select this component when Bus LVDS signaling into 50 Ohm loads is required for multi-point topologies. The standard PI90LV022 handles 100 Ohm loads; choose the B variant specifically for doubled drive current needs. Verify that the 3.3V supply and 650 Mbps speed requirements align with the system interface specifications.

Part Context

This device belongs to the PI90LV series of LVDS interface components produced by Pericom Semiconductor Corporation, now part of Diodes Incorporated. The series includes various drivers, receivers, and mux/repeaters designed for high-speed serial communication standards compliant with ANSI TIA/EIA-644.

Replacement Considerations

The PI90LV022WE serves as the base model for 100 Ohm loads. For direct functional replacement in 50 Ohm Bus LVDS designs, verify pin compatibility with other PI90LVB022 variants. No alternative part numbers are confirmed in the provided source material.
