The DSC2044FI1-H0006 is a MEMS-based XO (Standard) that outputs two identical 156.25 MHz HCSL clocks from a single resonator — a common reference for 10G Ethernet, PCIe Gen3, and FPGA transceiver banks.
Operates from 2.25V to 3.6V — a 3.3V rail is within the range, so no level translator is needed when the oscillator shares a supply with the PHY or FPGA bank.
