The DSC2311KI2-R0011: This MEMS-based oscillator delivers two synchronous 50 MHz CMOS outputs from one die, eliminating a second oscillator from the BOM and saving board area in dual-clock applications like Ethernet switch cores or FPGA reference trees.
The 2.25V to 3.6V supply range lets it run directly off a 2.5V or 3.3V rail without a dedicated LDO — a practical simplification for mixed-voltage digital boards.
Yes, the oscillator includes an enable/disable function. When disabled, the maximum supply current is 23 mA, allowing the clock output to be gated for power savings.
Yes, it is a drop-in replacement for a standard 50 MHz crystal oscillator in terms of frequency and CMOS output. The MEMS resonator offers better shock and vibration tolerance versus quartz, and the ±25 ppm stability meets most Ethernet and FPGA clock requirements. Confirm the supply voltage and enable polarity match your existing design.
