Automotive-grade MEMS clock for infotainment and telematics
The DSC1001BI2-022.5790T is a MEMS-based XO (Standard) oscillator delivering a 22.579 MHz CMOS output — the exact frequency needed for 44.1 kHz audio sample-rate clocks in automotive infotainment head units and digital signal processors.
Timing margin and supply flexibility
The supply voltage spans 1.8V to 3.3V, so the same oscillator BOM line serves 1.8V-core SoCs and 3.3V peripheral rails without a level translator on the clock output.
Housed in a 4-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm — this is the standard 5.0 x 3.2 mm oscillator footprint, compatible with industry-standard land patterns and reflow profiles. Surface-mount mounting on a standard PCB; the no-lead package keeps the parasitic inductance low at 22.579 MHz, so the CMOS output edge rate is clean without series termination resistors in most layouts.
