The 100 MHz frequency aligns with the base reference for PCIe Gen 1/2/3 (100 MHz ±300 ppm), and the ±25 ppm stability of this part provides substantial margin against the 300 ppm total budget, leaving headroom for the PLL and board-level spread-spectrum if needed. The 2.25V to 3.6V supply range covers 2.5V and 3.3V rails, so the same BOM line can serve both voltage domains without a separate regulator or level translator on the clock input. ## 6-SMD footprint — board layout notes The 7.00 mm x 5.00 mm, 6-SMD no-lead package (0.90 mm seated height) is a standard form factor shared by many quartz oscillators, so the PCB footprint can often serve either a MEMS or a quartz device with a layout change. The no-lead construction means the terminations are flush with the package body—verify the solder-paste stencil aperture for a 0.50 mm pad width to avoid bridging between the signal and ground pads during reflow.","metaTitle":"DSC1124NL2-100.0000T - 100 MHz MEMS XO HCSL Output -","metaDescription":"100 MHz MEMS XO, HCSL output, ±25 ppm stability, -40°C to +105°C, 2.25V-3.6V supply.
