The DSC1001CE2-012.2880T: A 12.288 MHz MEMS-based oscillator in a 4-SMD, no-lead package — the frequency is a standard multiple of 8 kHz, directly usable in TDM, VoIP, and audio codec clock trees without an external PLL.
Supply flexibility and standby power savings
Accepts any supply from 1.8V to 3.3V — one line item covers 1.8V, 2.5V, and 3.3V logic rails, simplifying BOM planning for multi-voltage designs. Active current consumption is 6.3 mA max, typical for a MEMS XO at this frequency — no surprise for a 12.288 MHz CMOS output.
MEMS vs quartz: what the silicon resonator changes
Frequency stability is ±25 ppm — comparable to a basic quartz XO, not tight enough for precision GPS or Stratum 3, but adequate for general-purpose clocking in audio, telecom, and automotive body electronics.
The 3.20 mm x 2.50 mm footprint with 0.90 mm seated height fits standard oscillator pads — no layout change from a quartz XO of the same dimensions.
