MEMS XO with dual CMOS outputs at 24 MHz and 72 MHz
The DSC2311KL2-R0048T is a MEMS-based XO (Standard) from Microchip's DSC2311 series, delivering two independent CMOS clock outputs: 24 MHz on output 1 and 72 MHz on output 2.
Frequency stability is ±25 ppm across the full -40°C to 105°C industrial temperature range — tight enough for 10/100 Ethernet MAC reference clocks and USB full-speed crystal-less designs, where the ppm budget includes the oscillator plus the PHY's internal PLL.
Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a 0.90 mm seated height, the DSC2311KL2-R0048T fits under low-profile enclosures and alongside dense BGA components on a 4-layer board. The 0.90 mm height is a common constraint for mezzanine card spacing — confirm the keep-out zone above the oscillator when stacking boards at 5 mm pitch.
