Product details

100 MHz HCSL clock for PCIe and serial links

HCSL is the reference clock format for PCIe Gen1/2/3, SATA, and USB 3.0 — the 100 MHz frequency directly serves the PCIe reference clock tree without a PLL multiplier. Supply voltage spans 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without an intermediate LDO.

Industrial temp grade and MEMS reliability

6-SMD, No Lead package measuring 5.00 mm x 3.20 mm x 0.90 mm — the same footprint as standard 5x3.2 mm oscillators. Surface-mount reflow profile matches standard JEDEC solder profiles; no special bake required if the MSL is observed.

Frequently asked questions

What is the enable/disable function on DSC1124BI1-100.0000?

The Enable/Disable pin gates the output. When disabled, the oscillator stops switching and supply current drops from 42 mA max to 22 mA max. The pin is active-high by default — tying it low disables the output. This allows the system to power down the clock tree during sleep modes without removing the supply rail.
