The DSC2311KI2-R0034 is a MEMS-based XO (Standard) from Microchip's DSC2311 series, delivering two fixed CMOS output frequencies: 33.3333 MHz on output 1 and 26.041641 MHz on output 2.
The 6-VDFN package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a low-profile footprint that fits under a heatsink or in a tight mezzanine stack.
Output 1 is 33.3333 MHz and output 2 is 26.041641 MHz, both CMOS levels. These are fixed frequencies — not programmable — so confirm they match your FPGA reference clock and SoC core clock requirements before committing the BOM.
