SIT3372AC-4E3-30NZ204.800000

Oscillators Overview

The SiTime SIT3372AC-4E3-30NZ204.800000 is a differential MEMS VCXO operating at 204.8 MHz with ±50 ppm frequency stability and a ±1600 ppm pull range. It functions within a 2.8 V to 3.2 V supply voltage range, delivering a maximum supply current of 97 mA. The device utilizes LVPECL output signaling and is housed in a compact 7.0 x 5.0 mm SMD package. It supports an industrial temperature range from -40°C to +85°C.

Oscillators Feature Summary

• DualMEMS temperature sensing and TurboCompensation technology for dynamic performance against thermal gradients and vibration
• Integrated on-chip regulators filter power supply noise without requiring external LDOs
• Factory programmable for specific frequency, stability, voltage, and pull range combinations

Oscillators Applications

• Telecommunications equipment requiring precise clocking
• Networking infrastructure utilizing high-speed data transmission
• Industrial applications demanding robust timing in noisy environments

Oscillators Procurement Notes

Verify the exact ordering suffix matches the required pull range and output format. Confirm that the 7x5mm package aligns with PCB footprint constraints. Ensure the LVPECL output level compatibility with downstream logic inputs. Cross-reference the ±50 ppm stability requirement against system jitter budgets before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 204.8 MHz reference with significant pullability is required. The LVPECL output suits high-speed differential interfaces. Consider the integrated regulation benefits for simplified power designs. Evaluate the ±1600 ppm pull range against modulation requirements. Verify the 7x5mm package availability for assembly processes.

Oscillators Part Context

This part belongs to the SiT3372 family of ultra-low jitter differential VCXOs. The series covers frequencies from 1 MHz to 220 MHz with various output formats including LVDS and HCSL. The Elite Platform enables extensive programmability across multiple package sizes and voltage options.

Oscillators Replacement Considerations

Direct substitutes include other SiT3372 variants with matching 204.8 MHz frequency and LVPECL outputs. Check alternative packages like 3.2x2.5mm if space allows. Quartz VCXOs are not direct replacements due to lack of programmability and different environmental resilience.
