2 OUTPUT PCIE GEN1-2-3 SYNTHESIZER
DATASHEET
IDT5V41315
Recommended Applications
PCIe Gen1-2-3 Synthesizer for Common and
SRNS-clocked systems
General Description
The IDT5V41315 is a PCIe Gen1-2-3 clock synthesizer
suitable for use in both Common-Clocked and Separate
Reference clock with No Spread (SRNS) timing
architectures. The IDT5V41315 uses a 25MHz input to
generate 4 different output frequencies. The output
frequency is selectable via select pins.
Output Features
• 2 - 0.7V current mode differential HCSL output pairs
Features/Benefits
• 16-pin TSSOP or VFQFPN package; small board
footprint
• Outputs can be terminated to LVDS; can drive a wider
variety of devices
• OE control pin; greater system power management
• Industrial temperature range available; supports
demanding embedded applications
Key Specifications
• Cycle-to-cycle jitter: 80ps
• Output-to-output skew: <50 ps
• PCIe Gen2 phase jitter: <3.0ps RMS (Common Clock)
• PCIe Gen3 phase jitter: <1.0ps RMS (Common Clock)
• Low Phase Noise: 12KHz to 20MHz <6ps RMS
