The DSC1104AE1-100.0000T is a MEMS-based XO delivering a 100 MHz HCSL output — the differential signalling standard for PCIe, USB 3.x, and 10GbE reference clocks. HCSL swings 700-900 mV peak-to-peak into a 50-Ω termination to ground, which means the AC-coupling caps and termination resistors on the receiver side must match that swing for proper edge rates.
6-VDFN with exposed pad, 7.00 x 5.00 mm footprint, 0.90 mm seated height.
Buyers need immediate availability to avoid production delays.
Pricing affects sourcing decisions and cost budgets.
Lead time impacts supply chain planning and project timelines.
Designers need drop-in alternatives for risk mitigation or second-sourcing.
Voltage compatibility is critical for circuit integration.
Physical dimensions must match board layout and assembly constraints.
