Product details

What this 148.5 MHz MEMS oscillator does that a quartz can't

The DSC1003DL5-148.5000T is a MEMS-based XO that delivers a fixed 148.5 MHz CMOS clock with ±10 ppm frequency stability across the full -40 to 105°C industrial-automotive temperature range. It is rated for under-hood and cabin modules where the ambient temperature hits 105°C and the clock must stay within ±10 ppm of 148.5 MHz — think ADAS camera serializers, automotive Ethernet PHYs, or infotainment SerDes links. Supply voltage spans 1.7V to 3.6V, so it can run directly from a 1.8V or 3.3V rail without an external LDO.

Package, footprint, and board-level fit

Housed in a 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm.

Frequently asked questions

How can I order DSC1003DL5-148.5000T or check stock and price?

Submit an RFQ through this page. The part is active and sourced through independent distribution — we confirm availability and current pricing per your BOM quantity at quote time.

Is DSC1003DL5-148.5000T AEC-Q100 qualified?

Yes, the ratings field explicitly lists AEC-Q100. That means it has passed automotive-grade reliability stress tests including temperature cycling, ESD, latch-up, and extended life — suitable for under-hood and cabin modules where ambient temperature reaches 105°C.

Can DSC1003 be used as a drop-in replacement for DSC1002?

The evidence does not confirm pin-compatibility between DSC1003 and DSC1002. Both are 4-SMD no-lead MEMS oscillators from Microchip, but the electrical specifications (supply range, stability, output type) may differ. Verify the land pattern and electrical ratings against your BOM before substituting.

Is the DSC1003 series RoHS compliant?

The evidence does not explicitly list RoHS compliance. However, as an active Microchip product in a standard 4-SMD package, it is reasonable to expect RoHS compliance — confirm on the latest datasheet or certificate of compliance from Microchip.
