The DSC1101AI2-148.5000 is a MEMS-based XO (Standard) delivering a 148.5 MHz CMOS output — a common reference frequency for video clocking (SMPTE 424M), 10G Ethernet, and FPGA transceiver reference clocks. Its 2.25V to 3.6V supply range spans both 2.5V and 3.3V logic rails, so the same part fits a 3.3V FPGA bank or a 2.5V SerDes PLL without a level shifter.
CMOS output — single-ended, rail-to-rail swing, compatible with standard digital logic inputs.
Yes — the supply range is 2.25V to 3.6V, so 3.3V ±10% is well within spec.
The Standby pin disables the output and reduces supply current to 95 µA max, letting the oscillator be gated off between active periods.
6-SMD, no lead exposed pad — 7.00 mm x 5.00 mm body, 0.90 mm seated height.
Yes, if the board footprint matches the 6-SMD package and the supply voltage is within 2.25V–3.6V. The MEMS part offers better shock/vibration tolerance and no crystal aging drift.
