The MEMS resonator replaces a quartz crystal, giving better shock and vibration immunity than a traditional crystal oscillator — relevant for motor drives or outdoor telecom gear that sees mechanical stress. ## Industrial temperature range and ±10 ppm stability The ±10 ppm frequency stability keeps the clock edge within tight jitter budgets for 1 GbE or SFP+ modules — no external TCXO needed. The Enable/Disable function pulls the output to high-impedance and drops supply current from 58 mA to 22 mA, useful for power-gated designs. ## Active lifecycle — no end-of-life risk This part is suitable for new designs and volume production without a last-time-buy window. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1122CI5-047.9990T MEMS XO, LVPECL, 47.999 MHz, Active","metaDescription":"Microchip DSC1122CI5-047.9990T: MEMS-based XO (Standard), LVPECL output, 47.999 MHz, ±10 ppm stability, -40°C to 85°C.
