SIT3372AC-4E9-33NC30.720000

Oscillators Overview

The SiT3372AC-4E9-33NC30.720000 is a differential MEMS VCXO operating at 30.72 MHz with ±20 ppm frequency stability. It utilizes a 3.3 V supply and features HCSL output signaling within a 5 mm x 7 mm SMD package. The device supports a pull range of 60 ppm and operates across a temperature range of -20°C to +70°C, delivering ultra-low jitter performance suitable for noisy environments.

Oscillators Feature Summary

• Integrates on-chip regulators to filter power supply noise without requiring external LDOs
• Provides resistance to airflow, thermal gradients, shock, and vibration via DualMEMS technology
• Factory programmable for specific combinations of frequency, stability, voltage, and pull range

Oscillators Applications

• Telecommunications systems requiring precise clocking
• Networking equipment demanding low-jitter differential signals
• Industrial applications operating in electrically noisy environments

Oscillators Procurement Notes

Verify the exact suffix configuration against the manufacturer datasheet to ensure compatibility with specific board layouts and signal integrity requirements. Confirm that the HCSL output format matches the receiving component inputs. Check for any recent manufacturing changes or PCNs that may affect pinout or electrical characteristics prior to final design approval.

Oscillators Selection Notes

Select this component when a differential VCXO with HCSL outputs is required at 30.72 MHz. Ensure the application environment stays within the -20°C to +70°C operational range. Consider the 60 ppm pull range capability if frequency tuning is necessary. Verify that the 3.3 V supply voltage aligns with the system power architecture.

Oscillators Part Context

This part belongs to the SiTime Elite Platform family of MEMS oscillators. It replaces traditional quartz VCXOs by offering programmability and superior dynamic performance. The SiT3372 series is designed to eliminate customization costs and long lead times associated with custom quartz devices while maintaining high reliability.

Oscillators Replacement Considerations

Direct replacement requires matching the 30.72 MHz frequency, HCSL output type, and 3.3 V supply. Verify that the alternative component supports the same 60 ppm pull range and fits the 5x7 mm footprint. Ensure the substitute maintains equivalent jitter specifications for the target application.
