LVPECL output draws 58 mA max — typical for the logic family, but the wide Vdd tolerance lets the oscillator share a rail with the downstream PLL or SerDes without a dedicated LDO. Housed in a 6-SMD no-lead package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm. The footprint is standard for this form factor — no special fan-out or via-in-pad required.","metaTitle":"DSC1122CE5-077.0000 LVPECL MEMS Oscillator 77 MHz ±10 ppm","metaDescription":"DSC1122CE5-077.0000 Microchip MEMS oscillator, 77 MHz LVPECL output, ±10 ppm stability, 2.25-3.6 V supply, -20°C to 70°C.
