PI90LVB022L

Overview

The PI90LVB022L is a Low Voltage Differential Signaling (LVDS) multiplexer and repeater manufactured by Diodes Incorporated. It operates from a single 3.3V supply within an industrial temperature range of -40°C to +85°C. The device supports signaling rates up to 650 Mbit/s and meets ANSI TIA/EIA-644-1995 requirements. It features two differential inputs and outputs, with propagation delay typically at 3.5ns. The L suffix indicates availability in a 16-pin Thin Shrink Small Outline Package (TSSOP).

Feature Summary

• Multiplexing capability allows routing either input channel to one or both output channels via S0 and S1 control signals.
• Bus LVDS signaling design doubles output drive current to support multi-point configurations on 50 Ohm loads.
• Inputs are fail-safe against open, short, and terminated conditions, ensuring stable operation during undefined states.
• Outputs enter high impedance when disabled or when the supply voltage drops below 1.5V.

Applications

• Multipoint data transmission over controlled impedance media.
• Signal routing and cross-point switching in base-band communication systems.
• Clock distribution networks requiring signal splitting or re-routing.

Procurement Notes

Verify the package type matches the 'L' suffix designation for the 16-pin TSSOP configuration. Confirm that the application environment requires Bus LVDS signaling levels suitable for 50 Ohm loads rather than standard point-to-point 100 Ohm loads. Ensure supply voltage stability remains within the recommended 3.0V to 3.6V range to maintain specified electrical characteristics.

Selection Notes

Select this component when a system requires flexible signal routing between two differential pairs using a single integrated circuit. The PI90LVB022L is distinct from the PI90LV022 due to its enhanced drive strength for Bus LVDS applications. Verify that the required signaling rate does not exceed 650 Mbit/s and that the operating temperature falls within the industrial specification limits.

Part Context

This device belongs to the PI90LV022 family of LVDS interface components produced by Pericom Semiconductor Corporation, now part of Diodes Incorporated. The family includes variants for point-to-point connections and multipoint bus architectures. The PI90LVB022 specifically addresses the need for higher drive currents in multi-drop environments compared to standard LVDS drivers.

Replacement Considerations

The PI90LV022W serves as a functional equivalent for point-to-point applications but lacks the specific Bus LVDS drive characteristics of the PI90LVB022. Substitution requires verifying load impedance compatibility and ensuring the replacement package matches the board footprint constraints.
