That 480:1 ratio means a CAN transceiver or ECU that only needs the clock during active bus cycles can shut the oscillator off between messages without draining the battery.
The 4-SMD no-lead package measures 2.50 mm × 2.00 mm with a seated height of 0.90 mm — a small footprint that fits tight PCB real estate. The 0.098″ × 0.079″ land pattern matches standard 2.0 × 2.5 mm oscillator pads; no via-in-pad or microvia required for routing.
Yes, the DSC1001DL2-050.0000T carries AEC-Q100 qualification, which means it has passed automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up immunity. This qualifies it for under-hood and chassis-domain applications where ambient temperature reaches 105°C.
The oscillator operates from 1.8V to 3.3V, covering the two most common digital logic rails. No external regulator is needed if the board already has a 3.3V or 1.8V supply; the part auto-ranges within that window.
Functionally yes — it outputs a CMOS clock at 50 MHz just like a quartz-based XO. The MEMS resonator is more shock- and vibration-tolerant than quartz, and the ±25 ppm frequency stability is comparable to a basic quartz oscillator. However, the pinout and footprint (4-SMD, no lead) must match the board layout; confirm the land pattern matches the existing oscillator footprint before substitution.
