FIN1102MTC Equivalent & Substitute Parts

Part Overview

The FIN1102MTC is a 2-channel LVDS buffer and redriver IC manufactured by onsemi, designed for signal conditioning and retiming applications in high-speed digital interfaces. Operating at data rates up to 800 Mbps, this component accepts LVDS or LVPECL input signals and outputs LVDS-compatible signals with minimal propagation delay. The device is currently classified as obsolete, making identification of functionally equivalent alternatives essential for system redesign, legacy product support, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FIN1102MTC is evaluated based on the following critical parameters that define functional equivalence:

• Signal Type Compatibility: Input acceptance of LVDS or LVPECL signals; output generation of LVDS signals
• Channel Count: 2-channel configuration for dual-signal processing
• Data Rate Performance: Maximum throughput of 800 Mbps or greater
• Supply Voltage Range: 3V to 3.6V single supply operation
• Operating Temperature Range: -40°C to 85°C industrial temperature specification
• Package Form Factor: Surface-mount technology with compatible pin count and footprint dimensions
• Propagation Delay: Minimal signal delay suitable for timing-critical applications

The SN65LVDS122D from Texas Instruments is identified as a substitute part. While this device functions as a crosspoint switch rather than a dedicated redriver, it operates within the same supply voltage range (3V ~ 3.6V), supports the same operating temperature range (-40°C ~ 85°C), and is housed in a surface-mount package. Both components are classified as REACH Unaffected and carry the same ECCN and HTSUS codes, indicating regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

The SN65LVDS122D is an active product with current manufacturing support from Texas Instruments, providing supply chain continuity for applications requiring LVDS signal processing. Both the FIN1102MTC and SN65LVDS122D share identical supply voltage specifications (3V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and regulatory compliance status (REACH Unaffected, EAR99 classification).

Selection between these components should account for package footprint differences: the FIN1102MTC uses a 14-TSSOP package (0.173" width), while the SN65LVDS122D employs a 16-SOIC package (0.154" width). PCB layout modifications may be required to accommodate the different pin configurations and package dimensions. The SN65LVDS122D's active product status ensures long-term availability and technical support from the manufacturer.

Frequently Asked Questions (FAQ)

Q: Can the SN65LVDS122D directly replace the FIN1102MTC without circuit modifications?

A: Both devices operate within the same supply voltage range (3V ~ 3.6V) and temperature specifications (-40°C ~ 85°C). However, package differences (14-TSSOP versus 16-SOIC) require PCB layout redesign. Functional compatibility depends on the specific signal routing and circuit topology of your application.

Q: What is the primary difference between these two components?

A: The FIN1102MTC is a dedicated 2-channel LVDS redriver optimized for signal conditioning and retiming. The SN65LVDS122D functions as a crosspoint switch with 1 x 2:2 circuit configuration. While both process LVDS-compatible signals, their internal architectures and pin assignments differ.

Q: Why is the FIN1102MTC classified as obsolete?

A: Obsolete status indicates that onsemi has discontinued manufacturing and support for this component. The SN65LVDS122D, maintained as an active product by Texas Instruments, represents a viable alternative for new designs and legacy product updates.

Q: Are there any compliance or regulatory concerns when substituting these parts?

A: Both components share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS codes (8542.39.0001), indicating regulatory equivalence. Moisture sensitivity levels are identical (MSL 1 - Unlimited).

Q: What packaging considerations should be evaluated?

A: The FIN1102MTC uses 14-TSSOP packaging with 0.173" width, while the SN65LVDS122D uses 16-SOIC packaging with 0.154" width. Pin count and spacing differ between packages, necessitating PCB redesign and potential schematic modifications to accommodate the new component footprint.
