Two clock rails from one MEMS die
The DSC2311KI2-R0055T is a dual-output XO (Standard) from Microchip's DSC2311 series, delivering 16 MHz on output 1 and 27.034483 MHz on output 2 from a single MEMS resonator. This eliminates the need for two separate crystal oscillators on the board, saving one component line and the associated PCB area. The CMOS output levels track the supply rail, which spans 2.25V to 3.6V — covering 2.5V and 3.3V logic without an external level translator.
The 6-VDFN package measures 2.50 mm x 2.00 mm with a 0.90 mm height — a compact footprint that fits dense PCB layouts.
