Supply voltage spans 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without an external LDO — the LVPECL output swing scales with Vdd, and the receiver's common-mode range must match. ## 6-SMD package — layout checklist The 7.00 mm x 5.00 mm 6-SMD package with no-lead exposed pad requires a thermal-via array under the pad for best heat transfer — the datasheet's recommended land pattern is the starting point, not an option. Seated height is 0.90 mm max, so the oscillator fits under a 1.0 mm board-to-shield clearance — confirm the keep-out zone on the opposite side of the PCB.","metaTitle":"DSC1122AI1-155.5200T Microchip MEMS XO, 155.52 MHz LVPECL","metaDescription":"DSC1122AI1-155.5200T: Microchip DSC1122 series MEMS oscillator, 155.52 MHz LVPECL output, ±50 ppm stability, -40 to 85°C.
