Overview
The AD9572ACPZPEC-RL is a fully integrated dual VCO/PLL clock generator optimized for fiber channel applications. It provides seven clock outputs: two at 106.25 MHz, one at 156.25 MHz, one selectable at 100 MHz or 125 MHz, one at 33.33 MHz, and one at 25 MHz. The device operates from a single 3.3 V supply in a 40-lead LFCSP package. Jitter performance includes 0.22 ps rms (637 kHz to 10 MHz) at 106.25 MHz and 0.19 ps rms (1.875 MHz to 20 MHz) at 156.25 MHz.
Feature Summary
- Dual PLL cores with integrated loop filters and preprogrammed divide ratios
- Seven clock outputs supporting LVPECL, LVDS, and CMOS formats
- Low jitter performance of 0.19 ps rms at 156.25 MHz
- Supports 25 MHz input crystal or reference clock
Applications
- Fiber channel line cards
- Fiber channel switches and routers
- Gigabit Ethernet support circuits
- PCIe support systems
Procurement Notes
Verify the component against the official Analog Devices datasheet Rev. B specifications. Confirm that the 40-lead LFCSP package matches the required footprint and thermal characteristics. Ensure the operating temperature range of −40°C to +85°C aligns with the system environment requirements.
Selection Notes
Select this component when low phase noise and high integration are required for fiber channel networking. The fixed output frequencies eliminate the need for external programming. Verify that the power dissipation limits (0.71 W for LVDS, 1.07 W for LVPECL) fit within the board's thermal design constraints.
Part Context
This part belongs to the AD9572 series of clock generators. It is designed specifically for high-performance networking equipment requiring precise timing synchronization across multiple interfaces without complex configuration.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation.
