150 MHz LVPECL clock source with MEMS resonator
The LVPECL output delivers the differential signal swing needed for high-speed clock distribution to FPGAs, SERDES, and Gigabit Ethernet PHYs, where single-ended CMOS would pick up noise over long traces. Supply voltage spans 2.25V to 3.6V, so the oscillator can run from a 2.5V or 3.3V rail without a separate LDO.
Temperature grade and board-level fit
The 6-SMD, No Lead package (3.20 mm x 2.50 mm) with a 0.90 mm seated height fits tight PCB profiles; the small footprint demands careful decoupling placement directly under the supply pin to keep the LVPECL output jitter within the ±25 ppm stability window. The 58 mA max supply current at 150 MHz is typical for an LVPECL output at this frequency — the differential pair draws constant current regardless of the toggle rate.
No pin-compatible second source or official replacement is listed; the DSC1122 series is the active family. Confirm the exact ordering code suffix for the temperature grade and stability before committing to the BOM line.
