The HCSL (High-Speed Current Steering Logic) output provides the differential swing and common-mode levels required by PCIe without external termination resistors — the receiver's 50 Ω to ground on each leg sets the bias. ## Supply flexibility and enable/disable control The 2.5V to 3.3V supply range lets the same part serve 2.5V and 3.3V logic domains — no separate voltage variant or external LDO needed when moving between FPGA banks or switching to a lower-voltage SoC.","metaTitle":"DSC1224BL2-100M0000T 100 MHz HCSL MEMS Oscillator","metaDescription":"Active Microchip DSC1224BL2-100M0000T XO, 100 MHz HCSL output, ±25 ppm, -40°C to 105°C, 2.5V-3.3V supply, 6-VDFN package.
