Dual-frequency MEMS XO — 100 MHz and 125 MHz on one chip
The DSC2044FI2-F0012T is an active MEMS-based XO (standard oscillator) that outputs two frequencies simultaneously: 100 MHz on Output 1 and 125 MHz on Output 2, both HCSL logic levels. This dual-output architecture lets a single oscillator feed two clock domains — for example, a 100 MHz PCIe reference and a 125 MHz Ethernet MAC clock — without a second crystal or PLL.
Enable/Disable for system power management
The Enable/Disable function (pin-controlled) allows the oscillator outputs to be tri-stated, dropping supply current from 60 mA typical to 23 mA max.
