Product details

The DSC1123AL2-025.0000 is a 25 MHz LVDS MEMS oscillator from Microchip's DSC1123 series, qualified to AEC-Q100 Grade 1 (-40°C to +105°C). The MEMS resonator eliminates the startup reliability concerns of quartz — no activity dips, no frequency jumps over temperature. The LVDS output provides a differential signal with typical edge rates under 1 ns, suitable for clocking high-speed ADCs, FPGAs, or SerDes transceivers.

The wide supply range of 2.25V to 3.63V allows direct connection to 2.5V or 3.3V rails without an intermediate LDO.

Housed in a 6-SMD no-lead exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm.

Frequently asked questions

Is DSC1123AL2-025.0000 AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, which means it has passed the automotive-grade stress tests: temperature cycling, ESD, latch-up, and extended life at 105°C. Suitable for under-hood and cabin electronics.

What is the difference between DSC1123AL2-025.0000 and DSC1123BL2-025.0000?

The evidence does not contain a specification for the DSC1123BL2 variant. Based on Microchip's DSC1123 series naming convention, the 'A' and 'B' typically denote different temperature grades or stability options — confirm the exact BL2 datasheet for the delta. The AL2 variant is rated -40°C to 105°C with ±25 ppm stability.

Is DSC1123AL2-025.0000 RoHS compliant?

The evidence does not explicitly list RoHS compliance. Microchip's standard MEMS oscillator products are typically RoHS-compliant and lead-free per EU Directive 2011/65/EU, but this should be verified against the manufacturer's certificate of compliance for the specific date code.
