Product details

MEMS oscillator at 133.3333 MHz — what the standby and stability mean

For a 133.3333 MHz carrier, that is a maximum drift of ±6.67 kHz — enough margin for most Ethernet or FPGA reference clocks, but tight enough that the load capacitance and board layout must match the datasheet's recommended termination.

Microchip lists the DSC1033AE1-133.3333T as Obsolete. No stock-holding claim — sourced per order.

Package and mounting — 4-SMD with exposed pad

The 4-SMD, No Lead Exposed Pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm.

Frequently asked questions

Does the DSC1033AE1-133.3333T have a standby function?

Yes, the part includes a Standby (Power Down) function. When disabled, the supply current drops to 1 µA max, making it suitable for battery-powered or duty-cycled designs.
