RHFLVDS32AK1

Drivers, Receivers, Transceivers Overview

The RHFLVDS32AK1 is an engineering model of the RHFLVDS32A, a quad low-voltage differential signaling (LVDS) receiver designed for aerospace environments. It operates on a 3.3 V supply with a maximum absolute rating of 4.8 V and consumes 43 mW. The device supports data transmission up to 400 Mbps (200 MHz) and features CMOS outputs compliant with ANSI TIA/EIA-644. It includes internal fail-safe functions and cold spare buffers for all pins. The component is housed in a hermetic Ceramic Flat-16 package and operates within a temperature range of -55 °C to +125 °C.

• Radiation hardened design achieving best-in-class hardness to total ionization dose

Drivers, Receivers, Transceivers Applications

• Aerospace point-to-point baseband data transmission
• Low-power fast data transmission standards in space environments
• High-reliability communication systems requiring radiation tolerance

Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix K1 indicates an engineering model rather than a production flight unit. Confirm the specific quality level requirements against the datasheet's ordering information table. Ensure compatibility with the Gold lead finish specified for this variant. Review the shipping documentation requirements associated with engineering models prior to acquisition.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring radiation-hardened LVDS reception in aerospace settings. Consider the hermetic packaging for environmental protection. Evaluate the 400 Mbps speed capability against system bandwidth needs. Verify that the 3.3 V operating voltage aligns with the target power supply architecture.

Drivers, Receivers, Transceivers Part Context

This part belongs to the RHFLVDS32A family of rad-hard quad LVDS receivers manufactured by STMicroelectronics. It shares functional specifications with the production QML-V variants but is designated as an engineering model. The family utilizes proprietary CMOS processes with mitigation techniques for radiation hardness.
