FIN1048M

Overview

The FIN1048M is a quad LVDS receiver designed for high-speed interconnect applications. It translates Low Voltage Differential Signaling (LVDS) inputs to LVTTL outputs, featuring a typical differential input threshold of 100mV. The device supports data rates exceeding 400Mbps with a maximum propagation delay of 2.5ns and a pulse skew of 0.4ns. Operating on a single 3.0V to 3.6V supply, it consumes low power dissipation. Available in 16-lead SOIC and TSSOP packages, the FIN1048M includes fail-safe protection for open-circuit conditions and meets TIA/EIA-644 standards.

Feature Summary

• Translates LVDS signals to LVTTL levels for direct interface with standard logic circuits
• Includes fail-safe protection that ensures defined output states during open-circuit or shorted input conditions
• Features flow-through pinout architecture to simplify printed circuit board layout processes

Applications

• High-speed transfer of clock and data signals
• Point-to-point or multi-drop serial communication links
• Interfacing between LVDS sources and LVTTL destination devices

Procurement Notes

Verify the specific package variant required, as the base model number corresponds to the SOIC package while suffixes indicate TSSOP options. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the design accounts for the specified operating temperature range and voltage limits to maintain signal integrity and device reliability.

Selection Notes

Select this component when interfacing LVDS drivers with LVTTL receivers requiring high-speed data translation. Verify that the system operates within the 3.0V to 3.6V supply range and requires fail-safe behavior for unconnected lines. Consider the 16-lead package constraints and ensure adequate thermal management for the intended application environment.

Part Context

This device belongs to the FIN1048 series of high-speed differential receivers manufactured by onsemi (formerly Fairchild Semiconductor). It is part of a family of LVDS components designed for low electromagnetic interference and low power consumption. The series typically pairs with companion drivers like the FIN1047 to form complete transmission line interfaces.

Replacement Considerations

Check for pin-compatible equivalents such as the DS90LV047ATM/NOPB from Texas Instruments. Verify that any substitute maintains the same LVDS-to-LVTTL translation capability, operating voltage range, and package dimensions to ensure mechanical and electrical compatibility.
