MEMS XO with four outputs and two output types
Three channels run 25 MHz, and the fourth is configurable to 100 MHz or 156.25 MHz — covering a common Ethernet reference and a PCIe or SATA clock on the same die. Outputs are split between HCSL and LVCMOS, so this single oscillator can feed a PCIe reference clock (HCSL) and a logic-level system clock (LVCMOS) without a separate translator.
Supply range is 2.25 V to 3.6 V, meaning it runs on a 2.5 V or 3.3 V rail without an extra LDO.
The 20-VFQFN with exposed pad measures 5.00 mm × 3.20 mm and stands 0.90 mm tall.
