120 MHz MEMS XO with CMOS output
The DSC1033AI1-120.0000T is a MEMS-based XO (Standard) delivering a 120 MHz CMOS clock from a 3.3V supply rail. Output is CMOS, meaning it drives a rail-to-rail square wave into a standard digital input without external termination. The 120 MHz rate suits high-speed logic, Ethernet PHY reference clocks, or FPGA fabric clocks.
Industrial temperature and low-power standby
That sub-microamp sleep current lets a battery-backed design gate the oscillator off between active periods without draining the cell.
Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. The exposed pad underneath is the thermal path — ensure the PCB has a matching copper land and at least one via to the ground plane to keep the MEMS die within its operating range. The no-lead package is reworkable with hot air if the pad layout is clean and the board is pre-baked per the MSL rating.
