MEMS resonator, LVDS output, 10-460 MHz range
The DSC8123DI2-PROGRAMMABLE: This covers the common clock rates for high-speed serial interfaces (PCIe, SATA, Gigabit Ethernet) and FPGA reference clocks without needing a different crystal for each frequency.
For a 100 MHz reference, that is ±2.5 kHz of total drift — tight enough for most Ethernet PHY and SerDes PLLs without external VCXO trimming.
Package and board-fit
The 2.0 mm x 2.5 mm footprint is the same as many standard quartz oscillators, so the PCB layout can accept either technology.
