The DSC1001BI2-030.0000 is a MEMS-based XO (Standard) from Microchip Technology's DSC1001 series, delivering a 30 MHz CMOS output with ±25ppm frequency stability. For an ECU, ADAS sensor module, or infotainment system that needs a clean 30 MHz reference, this part saves the board space and supply-chain complexity of a separate crystal plus oscillator IC.
No last-time-buy window or successor part has been announced.
Industrial temperature range and wide supply voltage
The supply voltage range of 1.8V to 3.3V lets it run from a 3.3V rail or a 1.8V core supply without an external regulator, simplifying the power tree.
4-SMD no-lead package — rework and layout notes
Housed in a 5.00mm x 3.20mm, 4-SMD no-lead package with a seated height of 0.90mm. The 0.197" x 0.126" footprint is a standard oscillator land pattern — reflow profile follows the JEDEC J-STD-020 for a 4-layer board. Layout engineers should place the decoupling cap within 2 mm of the supply pin to keep the 7.2 mA switching current loop tight.
