Renesas Electronics 9DBL PCIe 零延迟缓冲器
IDT 9DBL PCIe 零延迟缓冲器是 3.3V 器件，支持 PCIe Gen1-4 共同时钟 (CC) 系统。 9DBL 还支持 PCIe Gen2 独立扩展频谱的分离式基准时钟 (SRIS) 系统。 缓冲器可直接连接到 85Ω 或 100Ω 传输线路，可选择集成输出终端。 通过用户定义的通电默认 SMBus 配置，可对 9DBL PCIe 零延迟缓冲器进行工厂编程。
特性
- Direct connection to 100Ω (xx41, xx42) or 85Ω (xx51, xx52) transmission lines
- SMBus-selectable features allow optimization to customer requirements:
- Control input polarity
- Control input pull up/downs
- Slew rate for each output
- Differential output amplitude
- Output impedance for each output
- 50MHz, 100MHz, or 125MHz operating frequency
- Customer defined SMBus power up default can be programmed into P1 device; allows exact optimization to customer requirements
- OE# pins; support DIF power management
- HCSL-compatible differential input; can be driven by common clock sources
- Spread Spectrum tolerant; allows reduction of EMI
- Pin/SMBus selectable PLL bandwidth and PLL Bypass; minimize phase jitter for each application
- Outputs blocked until PLL is locked; clean system start-up
- Device contains default configuration; SMBus interface not required for device operation
- Three selectable SMBus addresses; multiple devices can easily share an SMBus segment
- Space-saving 24-pin 4x4mm VFQFPN; minimal board space
