Product details

12.5 MHz MEMS XO with automotive-grade qualification

The DSC1001CI2-012.5000T is a 12.5 MHz MEMS-based oscillator from Microchip Technology's DSC1001 series, delivering a CMOS output in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm.

No pin-compatible second source or official successor is documented — the DSC1001 series is the sole reference. For a direct alternative, confirm the BOM position package and frequency tolerance before substituting.

MEMS base resonator — no quartz aging curve

The ±25 ppm stability is specified across the full temperature range, not just at 25 °C. The disable current of 15 µA supports wake-on-event architectures without a dedicated power switch.

Frequently asked questions

Is DSC1001CI2-012.5000T a drop-in replacement for a 12.5 MHz quartz crystal oscillator?

Functionally yes — it provides the same 12.5 MHz CMOS clock. However, the MEMS die has different supply-current and start-up characteristics than a quartz oscillator. Verify the supply voltage range (1.8-3.3 V), package footprint (3.20 mm x 2.50 mm 4-SMD), and output drive strength against your existing oscillator before substituting.

What is the frequency tolerance of DSC1001CI2-012.5000T?

Frequency stability is ±25 ppm across the -40 to +85 °C operating range. This is the total variation including temperature, supply voltage, and aging — not a room-temperature-only figure.
