DSC1121NI1-100.0000 MEMS Oscillator 100 MHz CMOS XO

The supply voltage range of 2.25 V to 3.63 V covers 2.5 V and 3.3 V logic rails with margin — no extra regulator needed if your board already runs one of those. For a 100 MHz clock, that is ±5 kHz of jitter budget — tight enough for most Ethernet PHY, FPGA, and MCU reference clock applications without needing a TCXO.

The 6-SMD no-lead package measures 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 — no via-in-pad required, and it reflows on a standard FR-4 board with a 0.5 mm stencil aperture for the ground pad.
