MEMS oscillator for automotive and industrial timing
The DSC1001CL5-024.0000T is a MEMS-based XO (standard) from Microchip's DSC1001 series, generating a 24 MHz CMOS clock output with ±10 ppm frequency stability. The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal — the scorch mark on a failed board is rarely the MEMS die itself.
Standby function and supply current
Active supply current is 6.3 mA max, which keeps the thermal budget low in a sealed 4-SMD no-lead package. The standby (power-down) feature drops consumption to 15 µA max — the oscillator stops and the output goes high-impedance, letting the system sleep without draining the battery. For a vehicle ECU that spends most of its life in sleep mode, that 15 µA standby current is the difference between a battery that lasts the parking interval and one that doesn't.
Supply voltage and package fit
Operates from 1.8 V to 3.3 V — a single oscillator covers the common logic rails without a separate regulator. The 3.20 mm x 2.50 mm 4-SMD no-lead package (0.90 mm seated height) is a drop-in replacement footprint for many standard quartz oscillators; the board layout stays the same.
Active product status — no last-time-buy notice, no EOL pressure. The DSC1001 series is current production and suitable for new designs. Sourced through independent distribution; quoted to order against the BOM quantity. Availability confirmed at RFQ.
