SIT8208AC-G1-18S-16.369000X

Oscillators Overview

The SIT8208AC-G1-18S-16.369000X is a MEMS-based standard clock oscillator manufactured by SiTime, operating at a fixed frequency of 16.369 MHz. It utilizes an LVCMOS/LVTTL output format and functions within a supply voltage range of 1.71 V to 1.89 V. The device features a frequency stability of ±20 ppm and supports a standby power-down mode. Designed for surface-mount installation, it is housed in a compact 4-SMD, no-lead package measuring 2.70 mm x 2.40 mm with a maximum height of 0.80 mm. The component operates reliably across an industrial temperature range of -20°C to +70°C.

Oscillators Feature Summary

• Utilizes silicon MEMS technology to replace traditional quartz oscillators, offering enhanced reliability and configurability.
• Supports low-power operation with a dedicated standby (power-down) function to minimize energy consumption during idle states.
• Provides flexible output drive capabilities through compatible LVCMOS and LVTTL signal formats.

Oscillators Applications

• Industrial control systems requiring stable timing references
• Consumer electronics utilizing serial communication interfaces
• Embedded computing modules needing precise clock synchronization

Oscillators Procurement Notes

Verify the specific suffix 'X' corresponds to the required tape-and-reel packaging quantity and orientation. Confirm that the AC grade temperature range (-20°C to +70°C) aligns with the target application environment, as opposed to the wider AI grade range. Ensure the 1.8V supply voltage matches the system design constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a fixed 16.369 MHz frequency is required with ±20 ppm stability. Choose the AC grade for applications operating between -20°C and +70°C. Opt for the 1.8V supply variant if the system logic levels are lower than 3.3V. The 4-SMD package is suitable for high-density PCB layouts where space is limited compared to larger crystal packages.

Oscillators Part Context

This part belongs to the SiT8208 series of standard clock oscillators from SiTime. The series leverages MEMS First technology to provide robust timing solutions. The AC designation indicates the commercial/industrial temperature rating, while the G1 suffix typically denotes specific pinout or configuration parameters defined by the manufacturer for this form factor.

Oscillators Replacement Considerations

Direct parameter-equivalent substitutes include SIT8208AI-G1-18S-16.369000Y and SIT8208AI-G1-18S-16.369000T. Note that these alternatives belong to the AI grade, which offers an extended temperature range of -40°C to +85°C compared to the AC grade's -20°C to +70°C limit. Verify thermal requirements before substitution.
