Oscillators Selection Notes

Select this oscillator when a precise 118.70248 MHz reference is required in space-constrained applications. The 1.8V operating voltage makes it suitable for low-power portable or battery-operated devices. Consider the 50 ppm stability specification for applications requiring moderate frequency accuracy over temperature variations. The enable/disable feature allows for dynamic power savings in systems with intermittent usage patterns.

Oscillators Part Context

This component belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series offers various frequency options within a standardized small outline package format. The 'OE' suffix typically denotes specific packaging or tape-and-reel configurations provided by distributors. This model represents a high-frequency variant designed for modern high-speed digital circuits requiring stable clock sources.

Oscillators Replacement Considerations

Direct replacements must match the 118.70248 MHz frequency, 1.8V supply voltage, and 2.0x1.6 mm footprint. Verify that substitute components offer comparable 50 ppm stability and LVCMOS output characteristics. Check if alternative manufacturers provide equivalent enable/disable functionality and current consumption profiles to ensure seamless integration into existing designs.
