Automotive-grade MEMS oscillator at 42.5 MHz
The DSC6001JI2B-042.5000T is a MEMS-based XO (Standard) from Microchip's DSC60XXB series, delivering a fixed 42.5 MHz output in CMOS logic levels. The 1.8V–3.3V supply range lets it drop into existing 2.5V or 3.3V clock trees without a level translator.
Rated at ±25 ppm frequency stability over the full -40°C to 85°C range, this oscillator holds the clock edge within 1,050 Hz of 42.5 MHz worst-case — tight enough for a CAN-FD or 100BASE-T1 PHY reference without external trimming.
Housed in a 4-VLGA package measuring 2.50 mm × 2.00 mm with a seated height of 0.89 mm, the DSC6001JI2B-042.5000T occupies roughly the area of a 0805 resistor.
Sourced through independent distribution; quantities confirmed and quoted per RFQ against the BOM line.
