The DSC1122AI2-150.0000T is a 150 MHz LVPECL-output XO built on a MEMS resonator — no quartz crystal inside, which eliminates frequency drift from mechanical shock and vibration that plagues crystal oscillators in motor-drive or outdoor telecom environments. Supply voltage spans 2.25 V to 3.6 V, so a single oscillator serves both 2.5 V and 3.3 V logic domains without a level translator on the output.
It is a MEMS-based XO, not a quartz crystal oscillator. The 6-SMD, no-lead exposed-pad footprint is common among 7.0 x 5.0 mm oscillators, but the pad layout and enable/disable logic polarity may differ from other vendors. Confirm the output type (LVPECL), supply range (2.25-3.6 V), and enable pin function against your current BOM part before substituting.
