SIT5001AI-2E-33VQ-51.840000T

Oscillators Overview

The SIT5001AI-2E-33VQ-51.840000T is a MEMS-based Voltage-Controlled TCXO (VCTCXO) manufactured by SiTime. It operates at a nominal frequency of 51.84 MHz with an LVCMOS output interface. The device is powered by a 3.3 V supply and draws a maximum current of 33 mA. It features a wide operating temperature range from -40°C to +85°C and offers high frequency stability of ±5 ppm. The component is housed in a compact 4-SMD, no-lead package measuring 3.20mm x 2.50mm with a maximum height of 0.80mm.

Oscillators Feature Summary

• Utilizes silicon MEMS technology for enhanced ruggedness and reliability compared to traditional quartz oscillators.
• Provides voltage-controlled tuning capability within the TCXO architecture for precise frequency adjustment.
• Delivers stable timing performance across industrial temperature ranges with low phase noise characteristics.

Oscillators Applications

• Telecommunications systems requiring precise frequency control
• Data communication infrastructure components
• Industrial timing systems demanding high stability

Oscillators Procurement Notes

Verify the specific suffix 'T' corresponds to the tape and reel packaging configuration required for automated surface-mount assembly processes. Confirm that the 3.3V supply voltage aligns with the target system's power rails. Ensure the -40°C to +85°C industrial temperature rating meets the environmental specifications of the end application. Cross-reference the DigiKey part number 1473-1528-2-ND for accurate sourcing details.

Oscillators Selection Notes

Select this component when voltage-controlled tuning is necessary alongside the high stability of a TCXO. The MEMS construction offers superior shock and vibration resistance compared to quartz alternatives. The 4-SMD footprint suits space-constrained designs. Verify that the LVCMOS output logic levels are compatible with the receiving circuitry. Consider the 33mA current consumption against total system power budgets.

Oscillators Part Context

This part belongs to the SiT5001 series, which represents SiTime's family of precision MEMS oscillators. The series integrates MEMS resonators with CMOS control circuitry on a single die. This specific model variant includes voltage control functionality, distinguishing it from standard fixed-frequency TCXOs. The series is designed to replace discrete crystal oscillator solutions in demanding applications.

Oscillators Replacement Considerations

Public confirmed substitute part numbers include SIT5001AI-2E-33VQ-51.840000Y. Both variants share identical electrical parameters and functionality; the difference lies solely in the packaging format. Ensure the replacement matches the required reel or tray configuration for manufacturing compatibility.
