20 MHz MEMS clock source — what it is
The DSC1033DI1-020.0000T is a MEMS-based oscillator from the DSC1033 PureSilicon™ series, delivering a 20 MHz CMOS output from a 3.3 V supply.
Microchip lists the DSC1033DI1-020.0000T as Obsolete. For a new design, a current-production MEMS oscillator in the same 2.5 mm × 2.0 mm 4-SMD package should be evaluated — the DSC1033 series itself is discontinued, so the replacement will come from a different series or vendor.
Industrial temperature grade and standby function
Active draw is 3 mA typ at 20 MHz.
