Product details

The DSC6003JI2A-048.0000T is a MEMS-based XO (standard oscillator) from Microchip's DSC60XX series, delivering a 48 MHz CMOS output with ±25 ppm frequency stability across the full -40°C to +85°C industrial temperature range. Supply voltage spans 1.71V to 3.63V, allowing it to run from a 1.8V, 2.5V, or 3.3V rail without an external LDO — a single part number covers multiple system power domains.

AEC-Q100 Qualification and Automotive Fit

This part carries AEC-Q100 qualification — the automotive IC stress test standard covering temperature cycling, ESD, and latch-up. The OEM auditor will ask for the PPAP documentation that accompanies this grade.

Obsolete Status and Sourcing Path

Microchip lists this exact order code as Obsolete.

Frequently asked questions

Is there a direct replacement for DSC6003JI2A-048.0000T?

No pin-compatible successor has been announced by Microchip. A functional replacement would require a board-level change — compare the MEMS oscillator's package (4-SMD, 2.50mm x 2.00mm), supply range, and output type against active DSC60XX variants or other AEC-Q100 XOs.

What does the enable/disable function do on this oscillator?

The enable/disable pin lets the system logic pull the output to high-impedance, stopping the clock signal without removing power. This is used for power gating in automotive ECUs during low-power sleep states.
