150 MHz LVPECL clock from a MEMS resonator
The DSC1122BE1-150.0000T delivers a 150 MHz LVPECL output from a MEMS resonator, eliminating the quartz-crystal startup and aging concerns. The LVPECL swing requires a 50-ohm terminated differential pair on the PCB — the trace impedance must match the receiver's input structure to avoid reflections at this frequency.
Listed as Active by Microchip — no last-time-buy window, no end-of-life notice. The DSC1122 series shares the same 6-SMD footprint across frequency variants, so a BOM change to a different frequency keeps the same PCB layout.
Commercial temperature grade limits deployment
The oscillator will not meet spec in an outdoor base station, engine bay, or cold-storage environment. For industrial applications, the DSC1122 series offers extended-temperature variants; confirm the suffix before committing the BOM.
