Product details

Frequency stability is rated at ±10 ppm — tighter than the ±25 ppm or ±50 ppm common on commodity quartz oscillators. For a 10 MHz clock, ±10 ppm is ±100 Hz of absolute error, which keeps the timing margin comfortable for USB full-speed (12 MHz) or 10/100 Ethernet reference clocks.

Supply range and current draw

The supply voltage range is 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails. Maximum supply current is 22 mA — typical for a 10 MHz CMOS oscillator; the actual draw depends on the load capacitance on the output.

Package, mounting, and temperature grade

Housed in a 6-SMD, no-lead exposed-pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. This limits deployment to indoor, office, or consumer environments. Not rated for industrial floor or outdoor telecom enclosures without active temperature management.

Frequently asked questions

Can DSC1121AE5-010.0000T replace a standard 10 MHz quartz oscillator?

Yes, it is a direct drop-in replacement for a 10 MHz quartz XO with CMOS output and enable/disable function. The MEMS base resonator means better shock tolerance (tested to 50 g) and faster lead times than quartz. The pinout and supply range are the same as industry-standard 7.0 x 5.0 mm oscillators.
