The DSC1121CL2-125.0000: No LTB window to manage, no successor migration to plan — this part stays on the line card.
Automotive-grade MEMS clock for harsh environments
The MEMS resonator construction inherently resists shock and vibration better than quartz — a practical advantage in engine-bay and chassis-mounted ECUs where quartz crystals can fracture under mechanical stress.
125 MHz CMOS with wide supply tolerance
The supply voltage accepts 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without an external regulator — one BOM line serves multiple voltage domains in mixed-signal designs.
6-SMD no-lead — reflow and layout notes
Housed in a 6-SMD no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm. No exposed thermal pad — standard reflow profile per JEDEC J-STD-020 applies; check the MSL rating before the bake decision.
