Product details

MEMS resonator with ±10 ppm stability across industrial temperatures

The DSC1101BL5-018.4320T is an active-production MEMS-based XO from Microchip Technology, delivering a 18.432 MHz CMOS output with ±10 ppm frequency stability over the full -40°C~105°C industrial range.

6-VDFN package and tape-and-reel for automated assembly

Housed in a 6-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — the 0.197" x 0.126" footprint matches common quartz oscillator pads, simplifying the BOM swap.

Frequently asked questions

How can I order DSC1101BL5-018.4320T or request a quote?

The DSC1101BL5-018.4320T is an active-production part.

What is the difference between DSC1101 and DSC1121?

The DSC1101 series includes a standby (power-down) function, while the DSC1121 series offers a different output-enable feature. The standby function in DSC1101 drops supply current to 95 µA max when disabled — useful for power-sensitive designs where the oscillator must be shut off without removing the supply rail.
