Four-channel HCSL clock source with dual-frequency outputs
This makes it a direct fit for PCIe Gen1/2/3 reference clocks or 25 MHz Ethernet PHY multiplied up to 125 MHz — one device replaces four discrete oscillators on the BOM.
Supply voltage tolerance and temperature grade
Rated for a 2.25 V to 3.6 V supply, the oscillator accepts 2.5 V or 3.3 V rails without an external LDO — useful when the board has a shared 3.3 V plane and the downstream logic runs at 2.5 V.
Package and board-level considerations
Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm), the part requires a thermal via array under the pad for heat sinking and a solder stencil aperture that covers 50-70% of the pad area to avoid voiding.
