DS90LV032AW-QML

Drivers, Receivers, Transceivers Overview

The DS90LV032AW-QML is a quad CMOS differential line receiver designed for ultra-low power dissipation and high data rates. It accepts low voltage (350 mV typical) differential input signals and translates them to 3V CMOS output levels. The device supports a TRI-STATE function for multiplexing outputs and features power-off high impedance LVDS inputs to minimize bus loading when VCC is absent. It operates within an extended temperature range of -55°C to +85°C and complies with ANSI/TIA/EIA-644 standards.

Drivers, Receivers, Transceivers Feature Summary

• Low chip-to-chip skew and low differential skew ensure accurate signal transmission.
• High impedance LVDS inputs provide minimal loading effect on the bus lines during power-off conditions.
• Accepts small swing (330 mV) differential signal levels for compatibility with various drivers.
• Compatible with ANSI/TIA/EIA-644 standards and pin-compatible with DS90C032A and DS26C32A.

Drivers, Receivers, Transceivers Applications

• High-speed point-to-point interface applications
• Military and defense systems requiring QML certification
• Ultra-low power dissipation environments

Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix matches the required package type, specifically CFP (NAD). Confirm the presence of the -QML designation to ensure compliance with Mil-Std-883, Method 5005 Group A quality conformance inspection requirements. Ensure the component meets the specified operating temperature range of -55°C to +85°C for your application environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad LVDS receiver with extended military temperature ratings (-55°C to +85°C) is required. It serves as a direct replacement for older PECL/ECL devices in high-speed interfaces. Ensure the design accommodates the specific NAD ceramic package dimensions and utilizes appropriate decoupling capacitors as recommended in the datasheet.

Drivers, Receivers, Transceivers Part Context

This part belongs to the DS90LV032A family of LVDS receivers. It is a specialized, radiation-tolerant version intended for space and military applications. Unlike standard commercial variants, it undergoes rigorous qualification processes including Mil-Std-883 testing to ensure reliability in harsh environments.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include DS90LV032AQML and DS90LV032AW-MLS. Both share identical functional specifications and packaging options. Verify that any replacement maintains the same QML or MLS qualification status if required by the system design.

Drivers, Receivers, Transceivers FAQ

What happens to the LVDS inputs when VCC is not present?

The device features power-off high impedance LVDS inputs, which assure minimal loading effect on the LVDS bus lines when VCC is not present.

How does the fail-safe feature work for open inputs?

If unused channel inputs are left open, internal high-value pull-up and pull-down resistors bias the input to set the output to a HIGH state, ensuring a stable known state.

Is the DS90LV032AW-QML compatible with RS-422 receivers?

Yes, the footprint of the DS90LV032A is the same as the industry standard 26LS32 Quad Differential (RS-422) Receiver.
