200 MHz HCSL — what it drives
The DSC1124CI2-200.0000: This oscillator delivers a 200 MHz HCSL output, the differential signaling standard for PCIe reference clocks and SerDes reference inputs. The MEMS resonator starts up faster than a quartz crystal — no millisecond wait for the oscillation to stabilize — which matters in power-gated designs where the clock must be ready before the PLL lock sequence.
Runs from 2.25V to 3.6V, covering both 2.5V and 3.3V rails without a separate LDO.
6-SMD no-lead package, 3.20 mm x 2.50 mm, seated height 0.90 mm.
