The 12.288 MHz output is a common telecom framing rate (/T1) while the 100 MHz output suits a high-speed SerDes reference or FPGA fabric clock — a single oscillator covering both domains saves a crystal slot and a buffer. ## Industrial temperature range and stability ## Wide supply and small footprint The 2.25V to 3.6V supply range lets the oscillator run directly off a 2.5V or 3.3V rail without an extra regulator. The 20-VFQFN exposed-pad package (5.00 mm × 3.20 mm, 0.90 mm height) keeps the board footprint compact; the exposed pad needs a thermal via pattern under the device for proper solder-joint reliability and heat dissipation. ## Active production with Enable/Disable function","metaTitle":"DSC400-0401Q0103KI1 XO (Standard) MEMS Oscillator","metaDescription":"DSC400-0401Q0103KI1 dual-output XO: 12.288 MHz + 100 MHz, HCSL/LVCMOS, ±50 ppm, -40°C to +85°C, 20-VFQFN.
