MEMS oscillator with HCSL drive for PCIe clock trees
The DSC8104BI2: Its 10 MHz to 460 MHz available frequency range covers common PCIe Gen1 through Gen4 reference clock rates, 100/125/156.25 MHz Ethernet, and SerDes PLL references — the blank (user must program) variant means the final frequency is set during manufacturing programming, not at the factory.
Maximum supply current is 42 mA at the highest frequency — budget this into the power rail; the standby function (pin-controlled) drops the output stage to near-zero quiescent current for system sleep modes.
Package, footprint, and assembly
Surface-mount assembly with a no-lead construction means the solder joints are under the package — verify the stencil aperture for adequate solder volume; the datasheet recommends a 0.15 mm stencil thickness for the pad geometry.
The DSC8104BI2 is a current catalog part, not a phase-out or NRND device.
