Operates from 2.25V to 3.6V, covering both 2.5V and 3.3V rails — a single BOM line works across mixed-voltage systems without a regulator swap. Housed in a 6-SMD, no-lead exposed-pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. The HCSL outputs require external series termination resistors (50 Ω to ground at each output) to set the differential swing; the termination is not integrated.

HCSL outputs are open-emitter and require a 50 Ω resistor from each output to ground, placed close to the oscillator pins. The differential swing is set by the current through these resistors; the termination is not integrated into the DSC1124."},{"question":"Is DSC1124AL2-100.0000 pin-compatible with other DSC1124 frequencies?","answer":"The DSC1124 series shares the same 6-SMD footprint and pinout across all frequencies.
