FIN1047M

Overview

The FIN1047M is a quad driver designed for high-speed interconnects utilizing Low Voltage Differential Signaling (LVDS) technology. It translates LVTTL signal levels to LVDS levels with a typical differential output swing of 350mV, providing low EMI and ultra-low power dissipation at high frequencies. The device supports data rates greater than 400Mbps, operates on a 3.3V power supply, and features a maximum differential pulse skew of 0.4 ns and a maximum propagation delay of 1.7 ns. It meets or exceeds the TIA/EIA-644 LVDS standard and includes power-off protection.

Feature Summary

• Translates LVTTL input signals to LVDS output levels for high-speed data transfer
• Flow-through pinout architecture simplifies printed circuit board layout processes
• Provides power-off protection to prevent bus contention during system power cycles

Applications

• High-speed clock distribution networks
• Data transmission over high-speed interconnects
• Systems requiring low electromagnetic interference signaling

Procurement Notes

Verify manufacturer documentation for current production status, as Fairchild Semiconductor operations have transitioned. Confirm package availability in 16-Lead SOIC or TSSOP formats. Ensure compatibility with existing LVDS receiver components such as the FIN1048. Check for updated specifications from ON Semiconductor if applicable.

Selection Notes

Select this component when LVTTL to LVDS translation is required for high-speed interfaces. The flow-through pinout is advantageous for dense PCB layouts. Ensure the design environment supports 3.3V operation and complies with TIA/EIA-644 standards. Consider pin compatibility with RS-422 and LVPECL devices if migration is planned.

Part Context

The FIN1047M belongs to the FIN104x family of LVDS drivers manufactured by Fairchild Semiconductor. It is often paired with companion receivers like the FIN1048. The device is part of a series designed for high-speed digital communication applications requiring low power and low noise performance.

Replacement Considerations

The FIN1047MTC variant offers the same functionality in a TSSOP package. Equivalent devices may include RS-422 or LVPECL compatible drivers with similar pinouts. Verify electrical characteristics and package dimensions before substitution.
