133 MHz MEMS oscillator for high-speed clocking
The DSC1033CE2-133.0000T is a 133 MHz MEMS-based XO with CMOS output, designed for applications requiring a stable, low-jitter clock source in a compact 3.20mm x 2.50mm 4-SMD package. Frequency stability of ±25 ppm ensures tight timing margins for high-speed serial interfaces like Ethernet, PCIe, or SATA, where even a few ppm drift can cause link errors. The MEMS resonator offers inherent shock and vibration immunity compared to quartz crystals, making this oscillator a fit for industrial or portable equipment that sees mechanical stress.
Power budget and standby operation
Active supply current is 10 mA max at 133 MHz, while the standby (power-down) mode draws just 1 µA max — a 10,000× reduction that lets a battery-powered system idle for months without draining the cell. The standby function is controlled via a dedicated pin, allowing the system to gate the clock when the peripheral or core is asleep, then wake and resume within the oscillator's start-up time.
Temperature grade and commercial environment
If your design sees -40°C or +85°C ambient — outdoor telecom, engine bay, factory floor — the DSC1033 family includes industrial-temperature variants; verify the full part number suffix before committing.
