Microchip lists the DSC1122CL1-156.2500T as Active — no EOL notice, no last-time-buy window. It is suitable for both new designs and production replenishment. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1122CL1-156.2500T – 156.25 MHz LVPECL MEMS Oscillator","metaDescription":"Active Microchip DSC1122CL1-156.2500T XO (Standard) with LVPECL output, 156.25 MHz, ±50 ppm stability, 2.25V–3.6V supply, industrial temp.

The supply voltage range is 2.25 V to 3.6 V, so a 2.5 V rail is within spec. The LVPECL output swing scales with Vdd, so confirm the receiver's input common-mode range at the chosen supply voltage."},{"question":"Is the DSC1122CL1-156.2500T a direct replacement for a quartz oscillator of the same frequency?","answer":"Pin-compatible with standard 6-pin SMD oscillators in the 3.2 mm x 2.5 mm footprint.
