FIN1022MX

Signal Switches, Multiplexers, Decoders 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.

Signal Switches, Multiplexers, Decoders 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.

Signal Switches, Multiplexers, Decoders 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.
