TMC2340AH5C1

Overview

The TMC2340AH5C1 is a Direct Digital Synthesis (DDS) integrated circuit manufactured by Fairchild Semiconductor. It features a 16-bit resolution and operates at a clock frequency of 40 MHz. The device utilizes a 32-bit tuning word width for precise frequency control. It is housed in a compact PPGA-121 package, measuring 34.16x34.16 mm, designed for high-density applications. The component supports the generation of analog waveforms including sine, triangular, and sawtooth shapes.

Feature Summary

• Generates analog waveforms such as sine, triangular, and sawtooth signals
• Utilizes a 32-bit tuning word width for high-resolution frequency synthesis
• Operates with a 40 MHz clock frequency and 16-bit output resolution

Applications

• High-performance instrumentation and measurement systems
• Advanced communication systems including wireless local area networks (WLANs)
• Embedded communication applications requiring stable signal generation

Procurement Notes

Verify RoHS compliance status prior to procurement, as sources indicate non-compliance for this specific part number. Confirm the active lifecycle status with the manufacturer or authorized distributors. Ensure the PPGA-121 package dimensions align with your PCB layout requirements. Validate that the 40 MHz operational frequency meets your system design specifications before finalizing orders.

Selection Notes

Select this component when a dedicated DDS solution is required for generating precise analog waveforms. The 32-bit tuning word width offers superior frequency resolution compared to lower-bit alternatives. Consider the PPGA-121 package size for space-constrained high-density designs. Ensure compatibility with existing software tools for embedded integration. Verify power supply voltage levels against the specified operating range.

Part Context

This component belongs to the TMC2340 series of Direct Digital Synthesis ICs from Fairchild Semiconductor. It is designed for applications requiring accurate frequency generation. The series typically includes variants with different packaging options, such as QFP-120, but the AH5C1 suffix specifically denotes the PPGA-121 configuration. It serves as a core signal generator within larger electronic systems.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official distributor catalogs for cross-reference data. Verify pinout and electrical characteristics carefully if considering alternative DDS ICs from other manufacturers.
