SIT8208AC-3F-28E-74.250000X

Oscillators Overview

The SiTime SIT8208AC-3F-28E-74.250000X is a MEMS oscillator operating at 74.25 MHz with LVCMOS/LVTTL output formats. It functions on a 2.8V supply voltage, drawing a maximum current of 31 mA during operation and 10 µA in disabled mode. The device provides ±20 ppm frequency stability across an industrial temperature range of -40°C to +85°C. It utilizes a 4-SMD, no-lead package measuring 5.0 mm x 3.2 mm with a maximum height of 0.80 mm. This component supports enable/disable functionality and features ultra-low phase jitter characteristics typical of the SiT8208 series.

Oscillators Feature Summary

• Ultra-low phase jitter performance for high-speed signal integrity
• 100% pin-to-pin drop-in replacement for quartz-based oscillators
• Configurable enable/disable control for power management
• Robust silicon reliability with low failure rates

Oscillators Applications

• SATA and SAS storage interfaces
• Ethernet networking equipment
• PCI Express peripheral connections
• Video transmission systems
• WiFi access points and routers

Oscillators Procurement Notes

Verify that the suffix 'X' corresponds to the specific tape and reel packaging quantity required for your assembly line, as this differs from standard tray or cut tape options. Confirm the 2.8V supply voltage compatibility with your system's power rails before integration. Ensure the 5.0x3.2mm footprint matches your PCB design constraints. Cross-reference the exact part number with official distributor catalogs to confirm current availability and lead times, as manufacturing schedules may vary.

Oscillators Selection Notes

Select this model when a 74.25 MHz clock signal is required with strict size constraints due to its 5.0x3.2mm package. Choose the 2.8V variant if your system architecture operates at this specific voltage level rather than 1.8V or 3.3V. The ±20 ppm stability is suitable for general timing applications where extreme precision is not critical. Consider the enable/disable feature if dynamic power saving is necessary for the specific application environment.

Oscillators Part Context

The SIT8208AC-3F-28E-74.250000X belongs to the SiT8208 family of MEMS oscillators manufactured by SiTime. This series is designed to replace legacy quartz, SAW, and overtone oscillators while offering superior reliability and shorter lead times. The AC grade indicates industrial temperature range compliance, and the 3F suffix typically denotes the 5.0x3.2mm package size within the product coding structure.
