3.3V PCIe Gen1- 5 Clock Generator Family
9FGL02x1/04x1/06x1/08x1 Datasheet
Description
The 9FGL02x1/04x1/06x1/08x1 devices prise a family of 3.3V PCIe Gen1- 5 clock generators. There are 2, 4, 6 and 8 outputs versions available and each differential output has a dedicated OE# pin supporting PCIe CLKREQ# functionality.
PCIe Clocking Architectures
- mon Clocked (CC)
- Independent Reference (IR) with and without spread spectrum
(SRIS, SRNS)
Typical Applications
- Servers/High-Performance puting
- n VME Storage
- Networking
- Accelerators
- Industrial Control
Output Features
- 2, 4, 6, or 8 100MHz PCIe output pairs
- One 3.3V LVCMOS REF output with Wake-On-LAN (WOL) support
- See AN-891 for easy AC-coupling to other logic families
Key Specifications
- 90fs RMS typical jitter (PCIe Gen5 CC)
- < 50ps cycle-to-cycle jitter on differential outputs
- < 50ps output-to-output skew on differential outputs
- ±0ppm synthesis error on differential outputs
Features
- Integrated terminations for 100Ω and 85Ω systems save 4 resistors per output
- 112- 206 m W typical power consumption (at 3.3V)
- VDDIO rail allows 35% power savings at optional 1.05V
(9FGL06 and 9FGL08 only)
- Devices contain default configuration; SMBus not required
- SMBus-selectable Features allows optimization to customer...
