Product details

MEMS XO with LVPECL output at 47.999 MHz

The DSC1122CI5-047.9990T is a MEMS-based XO (Standard) from Microchip's DSC1122 series, delivering a 47.999 MHz LVPECL output. 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.
