The DSC1001BI2-003.1250: This is a MEMS-based standard oscillator (XO) that delivers a 3.125 MHz CMOS clock output with ±25 ppm frequency stability — tight enough for a CAN bus or sensor timing reference without external tuning. The supply voltage range spans 1.8 V to 3.3 V, so the same part can be used across multiple power domains without a dedicated regulator — a single BOM line covers 1.8 V, 2.5 V, and 3.3 V rails.
Housed in a 4-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard 5×3.2 mm footprint that matches many quartz oscillator land patterns.
The base product number DSC1001 covers the series; the full order code DSC1001BI2-003.1250 encodes the specific frequency, stability grade, and temperature range.
