Product details

Active MEMS XO at 100 MHz with HCSL drive

Supply voltage spans 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without an external regulator; the 42 mA max supply current covers the HCSL output stage and the MEMS PLL core.

Commercial temp grade and ±25 ppm stability

Frequency stability of ±25 ppm across the full temperature range means the 100 MHz clock stays within 2500 Hz of nominal — tight enough for a 1 GbE reference or a PCIe Gen 1/2 spread-spectrum clock, but check the jitter budget if the downstream SERDES requires sub-1 ps RMS phase noise.

6-SMD package and board layout note

Housed in a 6-SMD, No Lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm — the same footprint as many quartz oscillators in this form factor, so a layout swap from a quartz XO to this MEMS part often requires only a BOM change, not a board spin.

Frequently asked questions

Can DSC1104BE2-100.0000 replace a standard 100 MHz HCSL oscillator?

Yes, if the existing oscillator is a 6-SMD, No Lead package with a 5.00 mm × 3.20 mm footprint and operates from a 2.25V–3.6V supply. The MEMS base resonator eliminates quartz start-up delay and frequency-pull sensitivity, but confirm the downstream jitter tolerance — the ±25 ppm stability is typical for PCIe and Ethernet reference clocks, not for ultra-low-jitter SERDES that require sub-1 ps RMS phase noise.
