Product details

The 2.25V to 3.6V supply voltage range means this oscillator can run directly off a 2.5V or 3.3V rail without an intermediate regulator, simplifying the power tree on mixed-voltage boards.

Industrial temperature and MEMS reliability

The MEMS base resonator provides inherent shock and vibration resistance compared to quartz crystal oscillators, reducing the risk of frequency jumps in high-g environments.

Housed in a 6-SMD, No Lead package measuring 7.00mm x 5.00mm with a seated height of 0.90mm (0.035"), this oscillator fits standard 7x5 mm oscillator footprints and is compatible with reflow soldering profiles. Surface-mount mounting type with no leads means the package sits flush on the PCB, reducing parasitic inductance and improving high-frequency signal integrity.

Sourced through independent distribution channels.

Frequently asked questions

What is the frequency stability of DSC1121AL5-024.5760?

The frequency stability is ±10 ppm over the full operating temperature range and supply voltage variation. This tight stability is sufficient for most Ethernet, USB, and wireless base station clocking requirements.

Can DSC1121AL5-024.5760 be used as a replacement for quartz oscillators?

Yes, it is a drop-in MEMS replacement for standard 7x5 mm quartz oscillators with the same footprint and supply voltage range. The MEMS resonator offers better shock and vibration immunity, but the electrical interface (CMOS output, Enable/Disable) is identical.
