Three ways to match your needs, or quickly contact FCom’s engineering team.

By Package & Size

From ultra-miniature SMD sizes (such as 1.6 × 1.2 mm and 2.0 × 1.6 mm) designed for high-density IoT wearables and portable electronics, to robust 7.0 × 5.0 mm systems and traditional through-hole DIP-14 layouts for high-reliability industrial hardware.

Miniature SMD (≤2520)

Standard SMD

Through-Hole DIP

By Output Logic & Performance

Filter by system specifications to secure signal integrity. Choose standard CMOS/HCMOS for single-ended, low-frequency clocking, or select differential outputs like LVPECL and LVDS to minimize phase noise and jitter in high-speed datacom networking.

CMOS Output

Differential (LVPECL/LVDS)

Low Voltage

By Target Application

Optimize your vendor qualification with purpose-built series. Access low-current configurations for consumer gadgets and smart utilities, or choose AEC-Q200 qualified clock oscillators engineered to withstand automotive environments and severe thermal stress.

Consumer & IoT

Industrial Automation

Automotive Grade (AEC-Q200)
