Product details

125 MHz LVDS MEMS oscillator for automotive timing

The DSC1123BE2-125.0000T is a 125 MHz LVDS output MEMS-based oscillator from Microchip's DSC1123 series, rated for surface-mount assembly in a 6-SMD package. The LVDS differential output delivers clean edges for high-speed serial links, and the MEMS resonator eliminates the quartz crystal's shock and vibration failure mode — a real advantage on a board that sees engine vibration or frequent thermal cycling. Supply voltage spans 2.25 V to 3.63 V, so it runs from a common 3.3 V or 2.5 V rail without an extra regulator. The Enable/Disable function lets you gate the output for system power sequencing or test modes, pulling the supply current down to 22 mA when disabled.

AEC-Q100 Grade 2 qualification

This part carries AEC-Q100 qualification, meaning it has passed the automotive-grade reliability stress tests — temperature cycling, ESD, latch-up, and extended life. The -20°C to +70°C operating range aligns with passenger-cabin and infotainment domains; for an under-hood ECU that sees 105°C, you would step to the extended-temperature variant in the same DSC1123 family. Lifecycle status is Active, so there is no end-of-life clock ticking on this order code. It is suitable for both new designs and ongoing production replenishment — no last-time-buy planning needed.

Frequently asked questions

How does DSC1123BE2-125.0000T compare to DSC1123BE1-125.0000T?

The two order codes share the same 125 MHz frequency, MEMS resonator, and DSC1123 family. The 'BE2' suffix indicates a ±25 ppm stability grade and the -20°C to +70°C temperature range, while the 'BE1' variant typically carries a different stability or temperature grade. Confirm the specific datasheet marking for the BE1 code to verify pin compatibility — the 6-SMD footprint is identical, so a swap on the same board is possible if the timing budget and temperature range match.

Can DSC1123BE2-125.0000T be used with a 3.3 V supply?

Yes. The supply voltage range is 2.25 V to 3.63 V, so a 3.3 V rail is well within the operating window. The LVDS output common-mode voltage and swing are specified for that supply, and the 32 mA max supply current is drawn from the same rail.
