FIN1032M

Overview

The FIN1032M is a quad receiver designed for high-speed interconnect utilizing Low Voltage Differential Signaling (LVDS) technology. It translates LVDS levels to LVTTL signal levels, featuring a typical differential input threshold of 100mV. The device supports data rates greater than 400Mb/s with a maximum propagation delay of 2.5ns and a maximum differential pulse skew of 0.4ns. Operating on a 3.3V power supply within a range of 3.0V to 3.6V, it consumes 15mA when enabled and 5mA when disabled. It operates between -40°C and +85°C and is housed in a 16-lead SOIC package.

Feature Summary

• Translates LVDS signals to LVTTL levels for high-speed clock and data transfer
• Includes fail-safe protection for open-circuit, shorted, and terminated conditions
• Provides power-off protection to prevent interference during system shutdown
• Pin-compatible with equivalent RS-422 and LVPECL devices

Applications

• High-speed serial communication links
• Clock distribution networks
• Data bus interfaces requiring low EMI

Procurement Notes

Verify the specific ordering suffix to confirm the package type, as the base model number applies to both SOIC and TSSOP variants. Confirm RoHS compliance status through official documentation before integration. Ensure the design accounts for the recommended operating conditions regarding supply voltage and temperature ranges to maintain reliability.

Selection Notes

Select this component when a four-channel LVDS-to-LVTTL translation is required for high-speed applications. Consider pairing with the companion FIN1031 driver for optimized performance. Evaluate the 16-lead SOIC package for space-constrained designs where pin compatibility with RS-422 or LVPECL standards is beneficial.

Part Context

This device belongs to the FIN1032 series of LVDS receivers manufactured by Fairchild Semiconductor, now part of onsemi. It is specifically engineered to meet or exceed the TIA/EIA-644 LVDS standard. The series focuses on providing low power dissipation and low electromagnetic interference (EMI) characteristics suitable for demanding digital environments.

Replacement Considerations

Check for direct equivalents that match the 16-lead SOIC footprint and electrical specifications. Verify if alternative suppliers offer compatible quad LVDS receivers with similar propagation delays and power supply requirements.

FAQ

What is the function of the EN and EN pins?

These are the Driver Enable pins used to control the state of the outputs. When enabled, the receiver functions normally; when disabled, the outputs enter a high-impedance state.

How does the device handle open-circuit inputs?

The FIN1032 includes fail-safe protection that ensures a defined logic HIGH output level when the differential inputs are open-circuited, shorted, or terminated.

What is the maximum differential pulse skew?

The maximum differential pulse skew is 0.4ns, ensuring precise timing alignment between the rising and falling edges of the output signals.
