FIN1022MTCX

Signal Switches, Multiplexers, Decoders Overview

The FIN1022MTCX is a non-blocking 2x2 LVDS high-speed crosspoint switch manufactured by onsemi. It operates on a single 3.3V power supply (3.0V to 3.6V) and supports data rates up to 800 Mbps with a maximum toggle frequency of 900 Mbps. The device features fully differential input-to-output data paths, low jitter (worst case 190ps at 800 Mbps), and fast switching times (typical 1.1 ns). It includes open-circuit fail-safe protection and 7.5 kV HBM ESD protection. The component is housed in a 16-lead TSSOP package.

Signal Switches, Multiplexers, Decoders Feature Summary

• Supports multiple functions including crosspoint switching, multiplexing, demultiplexing, and signal splitting via LVTTL control inputs.
• Provides fully differential LVDS data paths for low noise generation and minimal pulse width distortion.
• Features direct interface capability with LVPECL signals at LVDS receiver inputs.
• Includes open-circuit fail-safe protection to prevent noise amplification during connection breaks.

Signal Switches, Multiplexers, Decoders Applications

• High-speed crosspoint switching systems
• LVDS to LVDS repeater circuits
• Signal distribution networks requiring 1:2 splitting

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'X' indicates tape and reel packaging rather than tube. Confirm current availability status as the base model may be obsolete. Ensure compatibility with existing PCB footprints for the 16-lead TSSOP package. Check for RoHS compliance documentation if required for the manufacturing environment.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a non-blocking 2x2 configuration is required for LVDS signal routing. It is suitable for applications needing direct LVPECL interfacing without level shifting. Consider the 3.3V operating voltage and the requirement for pull-down resistors on control inputs. Evaluate the 16-lead TSSOP package constraints against board space limitations.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the FIN1022 family of high-speed crosspoint switches originally developed by Fairchild Semiconductor, now part of onsemi. The family includes variants like the FIN1022MTC and FIN1022M, differing primarily in packaging and reel specifications. These devices are designed for communication and networking applications requiring reliable high-speed signal routing.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include DS90CP22M-8/NOPB and DS90CP22MX-8/NOPB from Texas Instruments. SN65LVCP22DR is listed as a similar alternative. Verify pinout and electrical characteristics match before substitution.
