9DS400A中文资料4 output PCIe PLL with spread injection数据手册Renesas规格书

描述 Description

The 9DS400 is a 4-output PCIe PLL with the ability to inject spread spectrum onto the incoming differential clock, while maintaining good phase noise.

特性 Features

• 4- 0.7V current-mode differential output pairs
• Supports Spread Injection mode and fanout mode
• Two pin selectable down spread amounts: 0.5% and 0.25%
• 50-110 MHz operation in PLL mode
• 50-400 MHz operation in Bypass mode
• Bypass mode
• Supports undriven differential outputs in PD# and SRC_STOP# modes for power management
• Output cycle-cycle jitter < 50ps
• Output to Output skew <50ps
• Phase jitter: PCIe Gen1 < 86ps peak to peak
• Phase jitter: PCIe Gen2 < 3.0/3.1ps rms
