Product details

What this MEMS oscillator replaces on the BOM

Supply range and standby — why they matter for the power budget

The supply range spans 2.25V to 3.63V, so the same oscillator works on a 2.5V or 3.3V rail without a separate LDO — one less voltage regulator on the BOM. Active current is 32 mA max at 114 MHz — that is the load on the 2.5V or 3.3V rail, so budget 106 mW worst-case for the oscillator alone.

6-SMD no-lead package, 3.20 mm x 2.50 mm body, 0.90 mm seated height — the same footprint as many quartz oscillators in this size, so a board laid out for a 3.2x2.5 mm XO can take this MEMS part without a PCB spin. Surface-mount only — no through-hole variant.

This is a current production part, so you can design it in without worrying about a last-time-buy window closing. No tray or tube option in this order code.

Frequently asked questions

What is the difference between DSC1103 and DSC1123?

The DSC1103 series outputs LVDS; the DSC1123 series outputs HCSL. Both are MEMS-based XOs in the same package and supply range, but the output logic family differs — LVDS for differential clock distribution, HCSL for PCIe reference clocks.

Is DSC1103CI5-114.0000T RoHS compliant?

The evidence does not list a RoHS compliance statement, but Microchip's standard MEMS oscillator series are typically RoHS-compliant and lead-free. Confirm with the datasheet or your Microchip FAE for the specific date-code lot.

Does DSC1103 have a standby function?

Yes. The Standby (Power Down) function disables the output and drops supply current to 95 µA max. The MEMS resonator stops, so the wake-up time is the oscillator start-up time — faster than a quartz crystal.
