SIT3373AC-2E9-25NZ245.760000

Oscillators Overview

The SiTime SIT3373AC-2E9-25NZ245.760000 is a MEMS-based Voltage-Controlled Crystal Oscillator (VCXO) operating at a nominal frequency of 245.76 MHz. It features LVDS output format and operates on a 2.5V supply voltage with a stability of ±35 ppm. The device supports an absolute pull range of ±70 ppm and functions within a temperature range of -20°C to +70°C. Packaged in a compact 6-SMD, no-lead exposed pad form factor measuring 3.2 mm x 5.2 mm with a maximum height of 0.90 mm, it utilizes surface mount technology for integration into high-speed digital systems.

Oscillators Feature Summary

• Utilizes silicon MEMS resonator technology for robust performance
• Provides differential LVDS output signals for noise immunity
• Offers programmable frequency and voltage configurations
• Supports wide absolute pull range for clock tuning applications

Oscillators Applications

• High-speed serial communication interfaces requiring precise clocking
• Data acquisition systems needing stable frequency references
• Telecommunications equipment utilizing VCXO tuning capabilities
• Industrial control systems operating in moderate temperature environments

Oscillators Procurement Notes

Verify the specific package dimensions and pinout configuration against the official datasheet before PCB layout finalization. Confirm that the LVDS output voltage levels are compatible with the receiving logic inputs. Ensure the power supply decoupling meets the manufacturer's recommendations to maintain signal integrity and jitter performance specifications during operation.

Oscillators Selection Notes

Select this component when a differential LVDS output is required alongside voltage-controlled frequency adjustment. The ±35 ppm stability suits applications demanding moderate precision without the cost of higher-grade oscillators. Consider the 3.2 mm x 5.2 mm footprint for space-constrained designs where standard crystal packages do not fit. Validate the ±70 ppm pull range against the system's maximum frequency deviation requirements.

Oscillators Part Context

This part belongs to the SiT3373 Elite Platform series, which focuses on low-jitter differential oscillators. The platform leverages SiTime's proprietary MEMS technology to replace traditional quartz components. The series offers extensive customization options for frequency, package, and output type, allowing designers to tailor timing solutions specifically for complex digital system architectures.

Oscillators Replacement Considerations

Direct replacements must match the 245.76 MHz frequency, LVDS output, and 2.5V supply. Verify that substitute parts offer comparable jitter performance and pull range. Check for identical package dimensions to ensure mechanical compatibility. Note that some alternatives may require different biasing or termination networks.
