FIN1108MTDX

Signal Buffers, Repeaters, Splitters Overview

The FIN1108MTDX is an LVDS 8-port high-speed repeater manufactured by onsemi. It operates within a supply voltage range of 3.0V to 3.6V and supports data rates exceeding 800Mbps. The device features 8 differential inputs and 8 differential outputs, with a typical output differential voltage of 330mV. It accepts LVPECL, HSTL, and SSTL-2 signals directly for translation to LVDS. Key electrical parameters include a maximum random jitter of 3.5ps and deterministic jitter of 135ps at 800Mbps. The component is housed in a 48-lead TSSOP package (JEDEC MO-153) and operates across a temperature range of -40°C to +85°C.

Signal Buffers, Repeaters, Splitters Feature Summary

• Supports direct input from LVPECL, HSTL, and SSTL-2 logic levels without external translation circuitry.
• Provides power-off protection and open-circuit fail-safe mechanisms to maintain signal integrity during inactive states.
• Includes a dedicated VBB reference output pin designed to facilitate AC coupling on the receiver inputs.

Signal Buffers, Repeaters, Splitters Applications

• High-speed interconnects utilizing Low Voltage Differential Signaling (LVDS) technology.
• Signal distribution systems requiring translation from single-ended or PECL standards to LVDS.
• Data transmission links where low electromagnetic interference (EMI) and ultra-low power consumption are required.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify that the ordering suffix matches the required packing method, as 'X' indicates tape and reel packaging while other suffixes may denote tube packing. Confirm the specific revision level against the manufacturer's current database, as part numbers may have transitioned from Fairchild Semiconductor nomenclature following integration into ON Semiconductor. Ensure compliance with RoHS directives if applicable to the target assembly process.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when an application requires buffering and translating multiple LVDS channels simultaneously. It is suitable for designs needing compatibility with LVPECL, HSTL, or SSTL-2 sources. Consider the 48-lead TSSOP package constraints regarding board space and thermal dissipation. Validate that the system timing budget accommodates the specified propagation delay and skew characteristics for the intended data rate.

Signal Buffers, Repeaters, Splitters Part Context

The FIN1108 belongs to the LVDS repeater family produced originally by Fairchild Semiconductor and now managed by ON Semiconductor. This series includes variants such as the FIN1101 (single port), FIN1102 (dual port), and FIN1104 (quad port). The FIN1108 serves as the high-density solution within this lineup, offering eight independent channels in a single integrated circuit.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The SN65LVDS108 from Texas Instruments is a comparable 8-port LVDS repeater. Verify pinout compatibility and electrical specifications before substitution. Note that ON Semiconductor part numbers formerly containing underscores may require adjustment to hyphenated formats in updated ordering systems.
