9VRS4420DKLFT

9VRS4420DKLFT is a main clock for avoton and rangley microserver in 48 pin VFQFPN package. It is driven with a 14.31818MHz crystal and generates a variety of clocks, including two DIF clocks suitable for Ethernet applications. An SMBus interface allows full control of the device.

• DIF outputs run in power-down, supports Wake-On-LAN
• 25MHz output can run in power down; supports Wake-On-LAN
• Selectable spread % on SRC, PCI, supports margining
• External 14.318MHz crystal; supports tight ppm
• CLKREQ# pins, support SRC power management
• LP-HCSL clock outputs, reduced power and board space
• LP-HCSL outputs internally terminated to 85Ω differential impedance; reduced board space
• Extended high commercial (0 to +85°C) operating range
• DIF cycle-to-cycle jitter <lt/> 85ps
• SRC/SATA cycle-to-cycle jitter <lt/> 85ps, SRC(6:1) and DIF(1:0) are PCIe Gen1-3 compliant
