The DSC1121NI1-065.0000T is a MEMS-based XO (Standard) oscillator from Microchip's DSC1121 series, delivering a fixed 65 MHz CMOS output from a 6-SMD, no-lead package measuring 7.00 mm x 5.00 mm.
Supply flexibility and output drive
Operating from 2.25 V to 3.6 V, the DSC1121NI1-065.0000T spans the 2.5 V and 3.3 V logic rails common in automotive and industrial systems — no separate voltage translation is needed when feeding a 3.3 V MCU or FPGA clock input. The CMOS output swings rail-to-rail, which simplifies clock distribution in point-to-point or single-load topologies; the 35 mA max supply draw at 65 MHz gives a rough power budget of 115 mW at 3.3 V before the load capacitance is factored in.
