Product details

It operates from a 1.8V to 3.3V supply rail, so a single part serves 1.8V, 2.5V, or 3.3V logic domains without a level translator on the output.

Standby power-down and current draw

Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard footprint that reflows with the same profile as other 5x3.2 mm oscillators. Surface-mount assembly; the no-lead construction reduces parasitic inductance compared to a through-hole crystal can, which matters for jitter-sensitive PLLs.

Frequently asked questions

Does DSC1001BI2-048.0000 support a standby or power-down mode?

Yes, the function is Standby (Power Down). When disabled, the supply current drops to 15 µA max, which lets the oscillator be gated off during system sleep without an external load switch.

Is DSC1001BI2-048.0000 compatible with 3.3V logic?

Yes, the CMOS output swings rail-to-rail, and the supply range includes 3.3V. No level translator is needed when feeding a 3.3V MCU or FPGA clock input.
