LVPECL is the differential standard for low-jitter clock distribution to high-speed SerDes, FPGAs, and 10G Ethernet PHYs — the 74 MHz rate fits reference-clock inputs that expect a clean, fast-edge clock rather than a single-ended LVCMOS signal. ## Supply range and enable/disable control The part operates from 2.25 V to 3.6 V, covering the common 2.5 V and 3.3 V logic rails without an external regulator. The part ships on Tape & Reel (TR), consistent with high-volume pick-and-place assembly.","metaTitle":"DSC1122CE5-074.0000T MEMS XO 74 MHz LVPECL ±10 ppm –","metaDescription":"DSC1122CE5-074.0000T MEMS oscillator: 74 MHz LVPECL output, ±10 ppm stability, 2.25–3.6 V supply, -20 to +70 °C, 6-SMD.

The base resonator is MEMS, not a quartz crystal. MEMS oscillators are inherently more resistant to shock and vibration and typically offer faster start-up than quartz-based XOs."},{"question":"Does the DSC1122CE5-074.0000T support a 2.5 V supply?","answer":"Yes. The supply voltage range is 2.25 V to 3.6 V, so both 2.5 V and 3.3 V rails are within spec."},{"question":"What is the difference between DSC1122CE5-074.0000T and DSC1122CE5-074.0000?","answer":"The suffix 'T' typically indicates Tape & Reel packaging. The DSC1122CE5-074.0000 (without 'T') would be the same oscillator in a different packaging format, such as cut tape or tube.
