FIN212ACBFX

Overview

The FIN212ACBFX is a high-performance serializer/deserializer (SerDes) component belonging to the µSerDes family, manufactured by Fairchild Semiconductor. It features a configuration of 12 parallel inputs and 2 serial outputs for serialization, and conversely 2 serial inputs with 12 parallel outputs for deserialization. The device operates within a supply voltage range of 1.65V to 3.6V and supports LVCMOS logic levels for both input and output interfaces. It is housed in a compact 32-WFQFN package with an exposed pad, measuring 5x5 mm, suitable for surface mount installation. The operational temperature range extends from -30°C to 70°C.

Feature Summary

• Integrates dual-channel serialization and deserialization capabilities within a single compact integrated circuit.
• Supports low-voltage CMOS logic interface standards for direct compatibility with digital systems.
• Utilizes a small form-factor surface-mount package designed for space-constrained board layouts.

Applications

• High-speed data transmission links requiring parallel-to-serial conversion
• Serial-to-parallel data recovery in communication interfaces
• Embedded systems with limited pin count needing expanded I/O capability

Procurement Notes

Verify the manufacturer origin carefully, as Fairchild Semiconductor's semiconductor assets were acquired by ON Semiconductor. Ensure the part number suffix matches the specific package variant required for your design. Confirm RoHS compliance status and moisture sensitivity level requirements before procurement to align with assembly processes.

Selection Notes

Select this component when a 12-bit to 2-bit or 2-bit to 12-bit data rate conversion is needed without external logic. Compare against other µSerDes variants if different pin counts or package types are preferred. Ensure the system power supply remains stable within the 1.65V to 3.6V range to maintain signal integrity and proper operation.

Part Context

This part is part of the µSerDes product line, which provides simple, low-power serializing and deserializing solutions. It serves as a bridge between parallel microprocessor buses and serial communication channels, reducing trace count and electromagnetic interference in dense electronic designs.

Replacement Considerations

Check for equivalents under the ON Semiconductor brand, as they inherited the Fairchild portfolio. Verify pinout compatibility and electrical specifications before substituting. Other models in the same series may offer different I/O configurations or packaging options.
