Product details

27 MHz MEMS oscillator – key ratings for clock-tree fit

The ±50ppm frequency stability over 0°C to 70°C is typical for general-purpose clocking in office equipment or indoor appliances.

Package and board layout – 4-SMD no-lead

Housed in a 5.00mm x 3.20mm 4-SMD no-lead package, 0.90mm seated height. The footprint is compatible with standard quartz XO layouts of the same dimensions – a drop-in swap for a quartz part is possible if the supply voltage and output type match. No via-in-pad required; standard SMD reflow profile applies.

Frequently asked questions

How can I order the DSC1030BC1-027.0000T or check availability?

This part is obsolete. We source it through independent surplus channels per your RFQ. Submit a quote request with your target quantity; we confirm availability and pricing at quote time. No stock-holding claim is made.

Does the DSC1030BC1-027.0000T have a standby function?

Yes, the function is listed as Standby (Power Down). When the enable pin is inactive, the supply current drops to 1µA maximum.

Can this MEMS oscillator drop into a quartz XO board?

If the existing quartz XO is a 5.0x3.2mm 4-pin SMD, 3V supply, CMOS output, then yes – the footprint and electrical interface are compatible. The MEMS die has different startup and jitter characteristics; review the datasheet timing specs against your system clock budget.
