CMOS output drives FPGA, MCU, or SoC clock inputs directly without a level translator — the 125 MHz rate suits Gigabit Ethernet MAC/PHY reference, PCIe gen1/2 spread-spectrum, and high-speed serial links.
Operating from 1.7 V to 3.6 V, this oscillator covers 1.8 V, 2.5 V, and 3.3 V logic rails without an external regulator. Active draw is 9.6 mA max at 125 MHz, which keeps the thermal rise low in the 2.50 mm × 2.00 mm 4-SMD no-lead package.
No pin-compatible second source is confirmed, but the DSC1003 series shares the same 4-SMD footprint and supply range across frequency variants — a frequency change within the family keeps the same PCB layout.
