100 MHz HCSL reference for PCIe clock trees
HCSL is the de facto clock standard for PCI Express interfaces — this oscillator delivers the 100 MHz reference directly, no level translation needed. Frequency stability is specified as ±10 ppm Absolute Pull Range (APR), covering voltage, temperature, and aging. That margin keeps the PCIe reference within the ±300 ppm tolerance required by the base spec, even with supply ripple or ambient drift. Supply voltage range is 2.25 V to 3.6 V, so the same BOM line works across 2.5 V and 3.3 V rails without a separate regulator.
Standby power-down for low-idle systems
When enabled, the oscillator draws 42 mA max at 100 MHz. That is typical for a MEMS HCSL output at this frequency; the MEMS die itself consumes less than a quartz equivalent, but the HCSL driver stage accounts for most of the current.
The 6-VDFN package measures 2.50 mm × 2.00 mm with a seated height of 0.90 mm max. That footprint is common across the DSC1104 family, so a single PCB land pattern covers multiple frequency variants. The small body and 0.50 mm pitch mean the pad stencil aperture should be matched to the land pattern in the datasheet — too much solder paste lifts the part and shifts the output duty cycle.
