SIT3373AI-1E3-33NH222.750000

Oscillators Overview

The SiTime SIT3373AI-1E3-33NH222.750000 is a MEMS Voltage-Controlled Oscillator (VCXO) operating at a nominal frequency of 222.75 MHz. It features LVPECL output signaling and requires a 3.3V supply voltage. The device exhibits a frequency stability of ±25 ppm and an Absolute Pull Range (APR) of ±20 ppm. It is housed in a compact 6-SMD, No Lead Exposed Pad package with dimensions of 7.00mm x 5.00mm. The component supports an operating temperature range from -40°C to +85°C and utilizes DualMEMS technology for enhanced dynamic performance.

Oscillators Feature Summary

• Integrates multiple on-chip regulators to filter power supply noise, eliminating the need for dedicated external LDOs.
• Utilizes DualMEMS temperature sensing and TurboCompensation technology to provide resistance against airflow, thermal gradients, shock, and vibration.
• Offers factory-programmable combinations of frequency, stability, voltage, output signaling, and pull range.

Oscillators Applications

• Telecommunications systems requiring precise timing
• Networking equipment demanding low-jitter clock signals
• Industrial applications operating in noisy environments

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure correct output type and pull range configuration. Confirm that the 6-SMD package matches the PCB footprint requirements. Check RoHS compliance status if restricted substances are prohibited. Ensure the operating temperature range aligns with the environmental conditions of the target application. Validate the LVPECL output compatibility with downstream receiver circuits.

Oscillators Selection Notes

Select this VCXO when low jitter and high linearity are critical for signal integrity. Consider the ±20 ppm APR for applications requiring moderate frequency tuning. The integrated regulation simplifies board design by reducing component count. Evaluate the 222.75 MHz frequency against system clock distribution needs. Ensure the 3.3V supply voltage is compatible with the system power architecture.

Oscillators Part Context

This component belongs to the SiT3373 Elite Platform series, designed for differential MEMS VCXO applications. It replaces traditional quartz oscillators in scenarios requiring programmability and robustness against mechanical stress. The platform supports frequencies up to 725 MHz, offering designers flexibility in clock generation without custom manufacturing lead times.

Oscillators Replacement Considerations

Direct substitutes include other SiT3373 variants with matching frequency and output types, such as SIT3373AI-1E2-33NB222.750000. Verify pinout compatibility and electrical specifications before substitution. Cross-reference absolute maximum ratings to ensure equivalent reliability under similar operating conditions.
