DS90C032W-QMLV

Overview

The DS90C032W-QMLV is a quad CMOS differential line receiver designed for high-speed point-to-point interfaces. It translates low voltage differential signals to CMOS levels with a supply voltage range of +4.5V to +5.5V and an operating temperature range of -55°C to +125°C. The device supports data rates up to 155.5 Mb/s, featuring a typical propagation delay of 1.0 ns and a maximum of 8.0 ns. It offers low differential skew (3.0 ns) and chip-to-chip skew (7.0 ns). Key features include Single Event Latchup immunity up to 120 MeV-cm²/mg, power-off high impedance inputs, and failsafe capabilities for open or terminated inputs.

Feature Summary

• Single Event Latchup (SEL) Immune up to 120 MeV-cm²/mg
• High Impedance LVDS Inputs during Power-Off
• Low Differential Skew and Chip to Chip Skew
• Pin Compatible with DS26C32A

Applications

• Military and Defense Applications
• Space-based applications requiring radiation tolerance
• High speed point-to-point interface systems

Procurement Notes

Verify the specific ordering suffix against the Package Option Addendum to confirm the exact package type (CFP NAD) and material specifications. Ensure that the procurement documentation includes the required radiation test reports and wafer level TID data if applicable for the intended mission profile. Confirm compliance with MIL-STD-883G testing requirements.

Selection Notes

Select this component when radiation hardness and wide temperature operation are critical. It serves as a direct replacement for the commercial DS90C032 in environments requiring QML certification. Consider the CFP package dimensions and thermal resistance characteristics for PCB layout. Verify that the system noise environment does not exceed the internal failsafe threshold without external biasing.

Part Context

This part belongs to the DS90C032QML family, which is qualified for military and space applications. It complements the DS90C031 driver to form a complete LVDS interface solution. The QML qualification ensures adherence to strict reliability standards for harsh environments, distinguishing it from standard commercial grade counterparts.

Replacement Considerations

The DS90C032E-QML is a pin-compatible alternative within the same family. For non-radiation-hardened applications, the commercial DS90C032B may be considered, though it lacks the specified radiation immunity and extended temperature range.
