20 MHz MEMS oscillator with ±10 ppm hold
The DSC1101NI5-020.0000T is a 20 MHz MEMS-based XO from Microchip's DSC1101 series, delivering CMOS output with ±10 ppm frequency stability across the full industrial temperature range. The MEMS resonator replaces a quartz crystal — it starts up faster and survives higher shock and vibration, which matters for portable and industrial gear where a quartz can crack or drift.
Supply rail flexibility and standby power-down
Runs on any rail from 2.25V to 3.6V — covers 2.5V and 3.3V logic without an extra LDO. The standby (power down) function pulls the output to high-Z and drops the current draw, letting a battery-powered system shut the clock tree when idle. Maximum supply current is 35 mA — budget this into the power budget for the oscillator alone; the actual draw is lower at lower supply voltages.
Housed in a 6-VDFN package measuring 7.00mm x 5.00mm with a seated height of 0.90mm — a low-profile, surface-mount footprint that fits tight board stacks.
This part is suitable for new designs and volume production without a last-time-buy clock.
