That means one oscillator replaces four cans on the board, saving real estate and reducing the BOM line count for a multi-rail clock tree. For a 200 MHz LVPECL clock, that jitter budget is tight enough to meet the reference-clock requirements of most 1 GbE PHYs and PCIe Gen 2/3 controllers without an external PLL clean-up. ## 2.25V–3.6V supply with enable/disable The wide 2.25V–3.6V supply range lets it run directly off a 2.5V or 3.3V rail — no extra LDO needed. Microchip lists the DSC400-2222Q0105KE2T as Active. The MEMS resonator construction also avoids the long lead times sometimes associated with quartz crystals.","metaTitle":"DSC400-2222Q0105KE2T MEMS XO – Quad LVPECL Oscillator","metaDescription":"Microchip DSC400-2222Q0105KE2T: MEMS-based XO, LVPECL outputs at 200/156.25/125/100 MHz, ±25 ppm stability, 2.25–3.6V supply, 20-VFQFN.
