This frequency set directly serves PCIe Gen 1/2/3 reference clocks (100 MHz) and Ethernet MAC/PHY or SerDes reference (125 MHz) on the same device. Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails without a separate regulator.
Housed in a 20-VFQFN Exposed Pad (5.00 mm x 3.20 mm, 0.90 mm height), the part requires a thermal pad on the PCB for proper heat dissipation.
The device provides four outputs: two at 125 MHz and two at 100 MHz, all HCSL logic levels.
