Product details

54.8352 MHz MEMS oscillator for industrial timing

An integrated enable/disable pin lets the system gate the oscillator output for power-down or test modes, saving the external load switch and its associated PCB area.

Package and supply compatibility

Housed in a 6-VDFN package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, this oscillator fits standard surface-mount assembly flows and reflow profiles.

Sourced through independent distribution, this part is quoted to order against the BOM quantity.

Frequently asked questions

Is the DSC1121AI3-054.8352T compatible with a 3.3 V supply?

Yes. The CMOS output swings rail-to-rail, so it drives 3.3 V logic inputs directly.

What is the frequency stability of the DSC1121AI3-054.8352T?

This is tight enough for 100BASE-TX Ethernet, USB full-speed, and most general-purpose clocking without needing a TCXO.

Does the DSC1121AI3-054.8352T have an enable/disable function?

Yes, the enable/disable pin lets you gate the output. When disabled, the supply current drops to a maximum of 35 µA, which is useful for power-sensitive designs.
