• Supports up to 10 inputs and 20 CMOS or 10 differential outputs
• Integrates up to eight DPLLs for hitless reference switching and holdover
• Includes MiToDSync and MiToDBasic time-of-day interfaces

Applications

• Line card timing for SyncE, SyncE+1588, routers, switches, and OTN systems
• Wireless base stations including 3G, W-CDMA, 4G/LTE, LTE-A, and 5G
• Remote Radio Units (RRU), Remote Access Networks (RAN), and small cells

Procurement Notes

Verify the specific suffix 'S' against the manufacturer's official documentation to confirm packaging details such as tape-and-reel configuration. Ensure that the ordering information matches the exact pinout and electrical specifications defined in the ZL3064x product brief DS20006635A before finalizing procurement.

Selection Notes

Select this component when designs require up to five independent synthesizers and extensive input/output flexibility. Verify that the required output frequencies fall within the 0.5 Hz to 750 MHz range and that the system can accommodate the 64-lead VQFN package dimensions. Confirm power supply requirements for both 1.8V and 3.3V domains.

Part Context

This part belongs to the ZL30641-ZL30645 family of line card timing ICs. The series offers scalable channel counts and I/O configurations while maintaining consistent core features like low-jitter synthesis and advanced DPLL capabilities for carrier-grade synchronization applications.

Replacement Considerations

Consult the ZL3064x product brief for confirmed substitute part numbers within the same family. Verify pin compatibility and feature parity before replacing existing components.
