The LVPECL differential output provides the low-jitter edge rates these serial protocols require, while the MEMS resonator gives better shock and vibration immunity than a quartz crystal in the same footprint. Microchip lists the DSC1122BI2-155.5200 as Active. This part is suitable for both new designs and ongoing production without a forced migration timeline. ## Package and enable/disable function Housed in a 6-SMD no-lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm. The Enable/Disable function lets the system shut down the oscillator output to save power — the disable current drops to 22 mA max versus 58 mA max when active. Surface-mount assembly with standard reflow profiles; no special handling beyond normal MSL precautions.","metaTitle":"DSC1122BI2-155.5200 MEMS XO 155.52 MHz LVPECL - Microchip","metaDescription":"Active Microchip DSC1122BI2-155.5200 MEMS oscillator, 155.52 MHz LVPECL output, ±25 ppm stability, -40°C to 85°C.
