151 MHz LVPECL clock source for high-speed logic
The DSC1122CI2-151.0000 is a MEMS-based XO (Standard) delivering a 151 MHz LVPECL output from a 2.25V to 3.6V supply rail. LVPECL logic levels require a DC termination to VCC – 2V, typically via a Thevenin-equivalent resistor pair to the supply and ground; the 151 MHz edge rate also demands controlled-impedance traces on the receiver side.
Housed in a 6-SMD no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, the footprint matches industry-standard 3.2×2.5 mm XO pads—a drop-in for existing layouts that expect that outline.
Active lifecycle—no last-time-buy pressure
This is useful in power-sensitive designs where the oscillator can be gated during sleep modes without an external load switch.
