SIT1602BC-31-18S-74.250000

Oscillators Overview

The SiTime SIT1602BC-31-18S-74.250000 is a standard MEMS clock oscillator operating at 74.25 MHz with 20 ppm frequency stability. It features an LVCMOS/HCMOS output format and operates within a supply voltage range of 1.62 V to 1.98 V. The device supports a 15 pF load capacitance and functions in temperatures from -20°C to +70°C. Housed in a 5 mm x 3.2 mm SMD package, it includes standby functionality for power management.

Oscillators Feature Summary

• MEMS-based timing solution offering robustness against shock and vibration compared to traditional quartz oscillators.
• Integrated standby mode allows for active power reduction when the oscillator is not in use.
• Configurable architecture enables flexible voltage and frequency combinations without custom mask sets.

Oscillators Applications

• Consumer electronics requiring low-power clock sources
• Industrial control systems needing reliable timing signals
• Automotive infotainment and instrumentation modules

Oscillators Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure compatibility with your system's voltage and temperature requirements. Confirm that the 5x3.2mm package dimensions fit your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards. Ensure the LVCMOS/HCMOS output levels match your receiving logic inputs.

Oscillators Selection Notes

Select this component when a 74.25 MHz frequency is required with 20 ppm stability and a 1.8V nominal supply. Consider the 5x3.2mm footprint for board space availability. Compare against other SiT1602 variants if different voltage ranges or industrial temperature grades (-40°C to +85°C) are needed. Verify that the single-ended output format suits your circuit design before finalizing the part number.

Oscillators Part Context

This part belongs to the SiT1602 family of MEMS oscillators, designed as drop-in replacements for quartz crystals and oscillators. The 'BC' indicates a specific performance grade, while '31' denotes the 5x3.2mm package size. The '18S' specifies the 1.8V supply voltage with standby capability. This series emphasizes smaller size and lower power consumption compared to legacy timing components.

Oscillators Replacement Considerations

Direct replacement requires matching the 74.25 MHz frequency, 1.8V supply, and 5x3.2mm package. Verify input/output logic levels and load capacitance requirements. Other SiT1602 parts with different voltage or temperature ratings may require circuit adjustments.
