What the dual-frequency output buys you
The DSC6021CI2A-00EK: This MEMS-based XO (Standard) delivers two independent CMOS clock outputs from a single 4-VDFN package: 48 MHz and 50 MHz. That means one oscillator can feed two clock domains — say a 48 MHz USB PHY and a 50 MHz Ethernet MAC — without a second crystal or a PLL multiplier. Typical current draw is 1.3 mA — low enough for battery-powered or thermally constrained designs.
Temperature range and stability for industrial use
That covers the industrial temperature band — factory-floor control cabinets, outdoor telecom enclosures, and engine-bay-adjacent electronics that see 85°C soak.
