200 MHz LVPECL clock source for high-speed serial links
The DSC1102AI2-200.0000 is a 200 MHz LVPECL oscillator from Microchip's DSC1102 series, built around a MEMS resonator rather than a quartz crystal. The LVPECL output delivers the differential swing needed for driving FPGA reference clock inputs, SerDes PLLs, and high-speed ADC/DAC sampling clocks without an external level translator.
MEMS resonator — shock-tolerant alternative to quartz
The MEMS base resonator eliminates quartz crystal startup issues and offers higher resistance to shock and vibration — a practical advantage in motor drives, outdoor telecom cabinets, and portable instrumentation where a quartz oscillator might fail or frequency-pull under mechanical stress. Standby (Power Down) function reduces supply current to 95 µA max when the clock is disabled, allowing the oscillator to be gated by a GPIO without an external load switch. The 58 mA max active current is typical for a 200 MHz LVPECL driver into a 50-Ω terminated line.
Active lifecycle — no end-of-life risk for new designs
It is suitable for both new design-ins and production replenishment.
