Frequently asked questions
Where can I buy DSC1033CI1-032.0000T and what is the current price?
No stock-holding claim is made here; all sourcing is quoted to order.
Is DSC1033CI1-032.0000T a direct replacement for standard 32 MHz quartz oscillators?
Yes, in most cases. The DSC1033CI1-032.0000T is a MEMS-based XO with CMOS output and a 3.3V supply, matching the footprint and function of a standard 32 MHz quartz oscillator. It does not require external load capacitors — the MEMS resonator is self-contained. Confirm the pinout matches your existing quartz oscillator's pin 1 (enable/standby) assignment before swapping.
Does DSC1033CI1-032.0000T require external load capacitors or termination?
No. The MEMS resonator and oscillator circuit are integrated inside the package. No external load capacitors or series termination resistors are needed for the CMOS output — it drives a standard CMOS load directly.
Is DSC1033CI1-032.0000T compatible with 2.5V supply?
The listed supply voltage is 3.3V. The evidence does not indicate 2.5V compatibility. For a 2.5V rail, check the DSC1033 series datasheet for a variant specified at that voltage.
