SIT3372AC-4B3-28NX51.200000

Oscillators Overview

The SiTime SIT3372AC-4B3-28NX51.200000 is a MEMS VCXO oscillator operating at a nominal frequency of 51.2 MHz. It utilizes HCSL output signaling and requires a 3.3V supply voltage. The device features ±50ppm frequency stability and an absolute pull range (APR) of ±345ppm. It is housed in a compact 6-SMD, No Lead package with dimensions of 3.2mm x 2.5mm. The unit supports surface mount installation and operates within a temperature range of -20°C to +70°C.

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 for resistance to airflow, thermal gradients, shock, and vibration.
• Factory programmable for specific combinations of frequency, stability, voltage, output signaling, and pull range.

Oscillators Applications

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

Oscillators Procurement Notes

Verify that the specific part number matches the required HCSL output format and 3.3V supply voltage configuration. Confirm the ±345ppm absolute pull range meets system tuning requirements. Ensure the 6-SMD no-lead package footprint aligns with the PCB layout design. Check that the operating temperature range of -20°C to +70°C is sufficient for the intended environment.

Oscillators Selection Notes

Select this component when a differential VCXO with HCSL outputs is required at 51.2 MHz. It is suitable for designs needing high immunity to environmental stressors like vibration and thermal gradients. The integrated regulation simplifies power design by removing external LDO dependencies. Consider factory programming options if standard parameters do not meet exact application needs.
