The DSC1101DI5-125.0000T: This is a current-production MEMS oscillator suitable for new BOM commits and volume builds.
125 MHz CMOS clock with ±10 ppm stability
This is a fixed-frequency XO (Standard) oscillator delivering a 125 MHz CMOS output — the most common interface for FPGAs, Ethernet PHYs, and SoC reference clocks. The ±10 ppm frequency stability holds the jitter budget for 1000BASE-T and USB 2.0 without external tuning.
Wide supply range and standby power-down
The supply voltage spans 2.25V to 3.6V — a single DSC1101DI5-125.0000T can serve a 2.5V FPGA bank and a 3.3V PHY on the same BOM line. No separate regulator is needed when the rail is within this window.
6-VDFN package — board layout notes
The 6-VDFN package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits under a BGA overhang or on a dense mixed-signal board.
