描述
The 9FG107 is a Synthesizer that provides 7 differential output pairs that are compliant to the Intel CK409/ CK410 specification. It provides support for PCI-Express, next generation I/O, and SATA. The part synthesizes several output frequencies from either a 14.31818 MHz crystal or a 25 MHz crystal. The device can also be driven by a reference input clock instead of a crystal. It provides outputs with cycle-to-cycle jitter of less than 85 ps and output-to-output skew of less than 85 ps. 9FG107 also provides a copy of the reference clock and 3 33 MHz PCI output clocks. Frequency selection can be accomplished via strap pins or SMBus control.
特性
- Generates common CPU/PCI Express frequencies from 14.318 MHz or 25 MHz
- Crystal or reference input
- 7 - 0.7 V HCSL differential output pairs
- 3 - 33 MHz PCI outputs
- 1 - REFOUT
- Supports Serial-ATA at 100 MHz
- Two spread spectrum modes: 0 to -0.5 downspread and +/-0.25% centerspread
- Unused inputs may be disabled in either driven or Hi-Z state for power management

PCIe Clocking Architectures (Common and Separate)
This is the first video in our PCIe series. In this video, we define PCIe architectures, focusing on common and separate clock architectures. Watch the rest of the video series below where Ron will cover the impact of different timing architectures.
