The DSC1123DI1-233.3333 is a 233.3333 MHz XO (Standard) with LVDS output built on a MEMS resonator — the MEMS base gives it faster startup and better resistance to shock and vibration than a quartz crystal oscillator in the same frequency range. Rated over -40°C to 85°C with ±50 ppm frequency stability, it holds the clock edge within tight tolerance across the industrial temperature band — relevant for 10GbE, SFP+ modules, and FPGA reference clocks where the LVDS pair drives a differential input directly.
3.3V supply, enable/disable function, 6-VDFN footprint
Operates from a single 3.3V supply rail, drawing 32 mA max when enabled and 22 mA max when disabled — the enable/disable pin lets the system power down the oscillator for low-power sleep modes without a separate clock buffer. Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm x 0.90 mm, the DSC1123DI1-233.3333 fits dense PCB layouts where board space is tight — the 0.50 mm pitch requires careful fan-out but is manageable on a standard 4-layer stack.
