Product details

The DSC1033AI1-075.0000T: Available through independent surplus distribution in lot-specific quantities.

75 MHz MEMS oscillator with CMOS output

This is a 75 MHz XO (Standard) oscillator built on a MEMS resonator rather than a quartz crystal. The CMOS output directly drives logic-level clock inputs on MCUs, FPGAs, or Ethernet PHYs without external level translation. Typical supply current is 4 mA max, dropping to 1 µA in standby (power-down) mode via the enable pin.

Package and board layout notes

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. The exposed pad on the underside provides a thermal path to the PCB ground plane — a solid via pattern under the pad improves heat spreading and mechanical stability during reflow.

Frequently asked questions

What is a replacement for DSC1033AI1-075.0000T?

No official successor or pin-compatible replacement is listed by Microchip Technology for this specific order code. For a functionally equivalent MEMS oscillator at 75 MHz with CMOS output and 3.3 V supply, consider the active DSC1000 or DSC2000 series from Microchip — confirm pinout and footprint compatibility against your PCB layout before committing.

What is the output type and supply voltage of DSC1033AI1-075.0000T?

The output is CMOS, and the supply voltage is 3.3 V. This makes it a direct drop-in for 3.3 V logic clock trees without external level shifters.
