Overview
The SiT3822AI-2D2-XXXX000.FP0000X is a programmable MEMS Voltage-Controlled Crystal Oscillator (VCXO) from the SiT3822 series. It features an LVDS output interface and operates within a frequency range of 220 MHz to 625 MHz. The device supports supply voltages of 2.5V and 3.3V, with a total frequency stability of ±25ppm. Designed for industrial temperature ranges (-40°C), it utilizes a 6-SMD, no-lead package. This specific part number represents an unprogrammed blank unit requiring user configuration.
Feature Summary
- Utilizes silicon MEMS technology for high reliability and shock resistance compared to traditional quartz.
- Provides differential LVDS output signals suitable for high-speed digital interfaces.
- Offers full programmability for frequency and pinout flexibility across the family.
- Supports voltage control for precise frequency tuning applications.
Applications
- High-speed serial communication transceivers
- Clock generation for data converters
- Test and measurement equipment timing
- Telecommunications infrastructure
Procurement Notes
Verify that the 'Blank' designation requires end-user programming before integration. Confirm supply voltage compatibility (2.5V/3.3V) and LVDS load requirements. Check current availability status as product lifecycle stages may affect long-term supply. Ensure ordering quantities align with manufacturer reel specifications.
Selection Notes
Select this model when differential LVDS outputs are required for frequencies between 220 MHz and 625 MHz. Choose based on the need for ±25ppm stability over the industrial temperature range. Consider the SiT3822 series if MEMS robustness against vibration is critical. Verify that the unprogrammed nature fits the manufacturing workflow.
Part Context
This component belongs to the SiT3822 family of high-performance differential VCXOs. It replaces legacy quartz oscillators in applications demanding superior performance-to-size ratios. The AI suffix indicates industrial temperature rating, while 2D2 specifies the package and pinout configuration within the SiTime ecosystem.
Replacement Considerations
Direct substitutes include other SiT3822 variants with pre-programmed frequencies or different output types such as LVPECL. Cross-reference with SiT3809 series for single-ended alternatives if differential signaling is not mandatory. Always verify pinout compatibility when replacing with non-blank programmable units.
FAQ
Is this oscillator pre-programmed?
No, this is an unprogrammed blank unit. The end user must configure the frequency and parameters using SiTime's programming tools.
What is the output signal type?
The SIT3822AI-2D2-XXXX000.FP0000X provides a differential LVDS output signal.
What is the operating frequency range?
The device supports programmable frequencies ranging from 220 MHz to 625 MHz.
