266.6667 MHz LVDS MEMS oscillator — what it replaces and why
The MEMS resonator is sealed at the die level, so the part resists vibration and shock better than a quartz can, and it starts up faster (typical 5 ms vs 10+ ms for a quartz oscillator).
Supply range, standby, and package fit
The supply voltage accepts 2.25V to 3.63V — a single 3.3V or 2.5V rail works without an extra regulator. The 6-SMD package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm, so it fits the same footprint as many quartz oscillators in the 3.2x2.5 mm form factor — check your board's pad layout against the DSC1103 datasheet's recommended land pattern before committing.
