FIN1022MX

Overview

The FIN1022MX is a non-blocking 2x2 LVDS high-speed crosspoint switch manufactured by onsemi. It operates on a single 3.3V power supply within a voltage range of 3.0V to 3.6V and supports data rates up to 800 Mbps. The device features fully differential input-to-output data paths with low jitter, achieving a worst-case peak-to-peak jitter of 190 ps at maximum speed using a PRBS 2^23−1 pattern. It provides open-circuit fail-safe protection and fast switching times typical of 1.1 ns. The component is housed in a 16-lead SOIC package.

Feature Summary

• Supports multiple configurations including crosspoint switching, multiplexing, demultiplexing, and signal splitting.
• Accepts LVDS and LVPECL signals directly at the receiver inputs.
• Includes open-circuit fail-safe protection to prevent noise amplification during disconnection.
• Features rail-to-rail common mode range for robust signal integrity.

Applications

• High-speed crosspoint switching
• 2:1 multiplexing
• 1:2 demultiplexing
• 1:2 signal splitting

Procurement Notes

Verify that the specific ordering code includes the 'X' suffix to confirm tape and reel packaging availability. Confirm compatibility with LVTTL control logic levels for enable and select pins. Ensure pull-down resistors are implemented on control inputs as required by specifications. Validate system design against absolute maximum ratings to ensure reliability across operating temperature ranges.

Selection Notes

Select this component for applications requiring low pulse width distortion and minimal channel-to-channel skew. Verify that the 75 ohm load requirement for driver outputs is met to maintain specified DC electrical characteristics. Consider the 16-lead package constraints for PCB layout. Ensure the application environment stays within the recommended operating temperature range.

FAQ

Can the FIN1022MX accept LVPECL signals directly?

Yes, the LVDS receiver inputs can directly interface with LVPECL signal levels without additional translation components.

What is the typical channel-to-channel skew?

The typical pin channel-to-channel skew is 35 ps.

How does the device handle open-circuit conditions?

It provides open-circuit fail-safe protection, ensuring outputs do not amplify noise if the connection is broken.
