That frequency sits in the range used for 10 GbE reference clocks, PCIe Gen 3/4 spread-spectrum references, and high-speed serial transceivers — the 156.25 MHz value is not arbitrary; it is the standard SerDes reference for 10 GbE and many FPGA transceiver banks. Supply voltage spans 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V logic rails without a dedicated LDO. The wide range means the same oscillator can serve a 3.3 V FPGA bank and a 2.5 V SoC on the same board by tying the supply to the respective rail — no level translation needed on the output side because CMOS logic thresholds scale with VDD. The MEMS resonator does not exhibit the same frequency-vs-temperature inflection that quartz crystals show near 0 °C; the ±50 ppm stability holds across the full band without a temperature-compensation curve. ## Package and footprint — 6-SMD, no lead Housed in a 6-SMD, No Lead package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. The 0.276\" x 0.197\" footprint is a standard oscillator land pattern — it matches the common 7x5 mm ceramic SMD footprint used across the DSC1101 family and many quartz-based oscillators, so a single PCB layout can accommodate multiple sources.","metaTitle":"DSC1101NI1-156.2500T – 156.25 MHz MEMS XO, CMOS","metaDescription":"Microchip DSC1101NI1-156.2500T: 156.25 MHz XO (Standard), CMOS output, MEMS resonator, 2.25-3.6 V, -40 to +85 °C, ±50 ppm stability, 6-SMD.
