Product details

The DSC1001BI1-012.2880 is a MEMS-based oscillator (XO) delivering a 12.288 MHz CMOS output — a common frequency for audio codec master clocks, USB isochronous timing, and serial bus reference clocks in automotive infotainment and telematics.

Standby power and supply flexibility

Supply voltage range spans 1.8V to 3.3V without a separate regulator — the same BOM entry works across a 3.3V I/O bank or a 1.8V core rail, simplifying multi-voltage designs. Max supply current is 6.3 mA during active operation — low enough that the 4-SMD no-lead package (5.00 mm x 3.20 mm) does not require thermal vias or copper pour for heat spreading.

Sourced through independent distribution on a quoted-to-order basis.

Frequently asked questions

Does DSC1001BI1-012.2880 support a standby mode for power saving?

Yes. The part includes a Standby (Power Down) function. When disabled, the supply current drops to 15 µA max, and the output goes high-impedance — useful for battery-powered or sleep-mode systems.

Is DSC1001BI1-012.2880 compatible with 3.3V systems?

Yes. The supply voltage range is 1.8V to 3.3V, so it works directly on a 3.3V rail without an external level translator or regulator.

What is the closest pin-compatible alternative to DSC1001BI1-012.2880?

Within the Microchip DSC1001 family, other frequency variants share the same 4-SMD no-lead footprint and supply range. A same-frequency peer from a different MEMS oscillator family (e.g., SiTime SiT8008) would require comparing pinout and control logic — confirm the standby function and enable polarity against your schematic before substituting.
