Product details

48 MHz MEMS XO with ±10ppm stability and CMOS output

The MEMS resonator replaces a quartz crystal, eliminating the startup-time jitter and vibration sensitivity that plagues quartz oscillators in motor-drive and outdoor telecom environments.

Wide supply range and standby power-down

Supply voltage spans 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without an external regulator. The standby (power-down) function drops current consumption to 95µA max — low enough to keep the oscillator alive on a backup battery during system sleep.

Active lifecycle, sourced to order

Product status is Active per Microchip. Sourced through independent distribution — quoted to order against the BOM quantity.

6-SMD no-lead exposed pad package

Housed in a 7.00mm x 5.00mm 6-SMD no-lead exposed pad package, seated height 0.90mm max. The exposed pad provides a thermal path to the PCB copper plane — critical for dissipating the internal MEMS driver heat in high-ambient environments. The no-lead design reduces parasitic inductance compared to a gull-wing package, keeping the 48 MHz CMOS edge clean.

Frequently asked questions

How can I order the DSC1101AI5-048.0000T or check current pricing and availability?

The DSC1101AI5-048.0000T is Active and available through independent distribution. No stock-holding claim is made — availability is verified per inquiry.

What is the output signal of the DSC1101AI5-048.0000T?

CMOS output, single-ended, rail-to-rail swing from the 2.25V to 3.6V supply rail. It drives standard CMOS logic inputs without external level translation.

What voltage range does the DSC1101AI5-048.0000T support?

Supply voltage range is 2.25V to 3.6V, covering 2.5V and 3.3V nominal rails with margin.

Can the DSC1101AI5-048.0000T replace a 48 MHz quartz oscillator as a drop-in?

Pin-compatible with standard 6-pin SMD quartz oscillators in the same 7.0mm x 5.0mm footprint. The MEMS resonator offers faster startup and better vibration immunity, but the output drive strength and load capacitance may differ — confirm the downstream logic input threshold and any series termination resistor on the existing board.

What is the closest pin-compatible alternative in the DSC1101 family?

The DSC1101 series includes multiple frequency and stability variants in the same 6-SMD no-lead package. For a direct CMOS-output 48 MHz alternative, the DSC1101AI5-048.0000 is the base product number without tape-and-reel suffix — same electrical specs.
