Product details

Active supply current is 10 mA max at 133 MHz; when the Standby (Power Down) function is asserted, the disable current drops to 1 µA max—a three-order-of-magnitude reduction that lets a system sleep without a separate power switch.

Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm—a compact footprint that fits tight PCB layouts without requiring a dedicated oscillator can. Surface-mount assembly at 3.3V supply; the exposed pad provides a thermal path to the PCB ground plane, though at 10 mA max draw the thermal demand is low.

Frequently asked questions

What is the frequency stability of this oscillator?

This is tight enough for most 100BASE-T Ethernet and general-purpose clocking applications without external trimming.

Does the DSC1033AI2-133.0000T support a standby or power-down mode?

Yes, the device includes a Standby (Power Down) function. When enabled, the supply current drops from 10 mA max to 1 µA max, allowing the system to conserve power during idle periods.
