FIN1028M

Overview

The FIN1028M is a dual receiver designed for high-speed interconnects utilizing Low Voltage Differential Signaling (LVDS) technology. Manufactured by Fairchild Semiconductor, it translates LVDS levels to LVTTL signal levels with a typical differential input threshold of 100mV. The device supports data rates greater than 400Mbps and operates on a 3.3V power supply. It features a maximum differential pulse skew of 0.4ns and a maximum propagation delay of 2.5ns. Packaged in a 14-lead TSSOP, it meets or exceeds the TIA/EIA-644 LVDS standard.

Feature Summary

• Flow-through pinout architecture simplifies printed circuit board layout processes.
• Integrated fail-safe protection ensures stable operation during open-circuit, shorted, or terminated non-driven input conditions.
• Power-off protection functionality prevents erroneous output states when the device is unpowered.

Applications

• High-speed transfer of clock signals in digital systems.
• High-speed transfer of data signals in communication interfaces.
• General purpose LVDS to LVTTL level translation applications.

Procurement Notes

Verify the specific suffix 'M' against the manufacturer's official documentation to confirm package type and temperature range specifications. Ensure compatibility with existing 3.3V logic families and LVDS drivers such as the FIN1025. Confirm RoHS compliance status through current datasheets prior to procurement.

Selection Notes

Select this component for designs requiring reliable LVDS reception at speeds exceeding 400Mbps. The 14-lead TSSOP package is suitable for space-constrained layouts. Consider pairing with compatible LVDS drivers and ensure proper termination resistors are used to maintain signal integrity according to TIA/EIA-644 standards.

Part Context

The FIN1028M belongs to the FIN102x series of LVDS receivers from Fairchild Semiconductor. This series includes companion drivers like the FIN1025 and crosspoint switches like the FIN1022. These components are engineered to work together to provide complete low-voltage differential signaling solutions for high-speed digital interconnects.

Replacement Considerations

Direct substitutes within the same family include the FIN1026. Verify pinout compatibility and electrical characteristics before substitution. Cross-reference with other LVDS receivers from different manufacturers if pin-compatible alternatives are required.
