Product details

156.25 MHz LVPECL clock for high-speed signal chains

The DSC1122CL1-156.2500T is a MEMS-based XO delivering a 156.25 MHz LVPECL output — a common reference frequency for 10 Gigabit Ethernet PHYs, FPGA transceivers, and high-speed ADC/DAC clocking.

Industrial temperature grade and MEMS reliability

The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz blank, reducing the risk of start-up failures in deployed systems.

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.

Frequently asked questions

Can the DSC1122CL1-156.2500T be used with a 2.5 V supply?

Yes. 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.

Is the DSC1122CL1-156.2500T a direct replacement for a quartz oscillator of the same frequency?

Pin-compatible with standard 6-pin SMD oscillators in the 3.2 mm x 2.5 mm footprint. The MEMS resonator means the start-up time and jitter profile differ from quartz — verify the downstream PLL's lock time and jitter tolerance in your specific application before substituting.
