Overview
Description
The 9VRS4420D is a main clock for Avoton and Rangley Microservers. 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.
Features
- 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
- I-temperature (-40°C to +85°C) version available; supports severe operating environments
- DIF cycle-to-cycle jitter < 85ps
- SRC/SATA cycle-to-cycle jitter < 85ps
- SRC(6:1) and DIF(1:0) are PCIe Gen1-3 compliant
