74 MHz LVPECL clock source with MEMS reliability
The DSC1122CE5-074.0000T is a MEMS-based XO delivering a 74 MHz LVPECL output with ±10 ppm frequency stability across its -20 °C to +70 °C operating range. 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.
