AD9546BCPZ-REEL7

Overview

The AD9546BCPZ-REEL7 is a dual DPLL digitized clock synchronizer in a 48-lead LFCSP package. It supports up to eight input references and provides ten clock outputs with frequencies up to 500 MHz. The device operates on a single 1.8 V supply (1.7 V to 1.89 V) and consumes 325 mA, dissipating 760 mW. It features two DPLLs for jitter cleaning and frequency translation, along with analog PLLs. The component includes nine UTS blocks, two IUTS blocks, and auxiliary NCOs for IEEE 1588 applications. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual DPLL architecture synchronizes 1 Hz to 750 MHz physical layer clocks with jitter cleaning.
• Ten configurable clock outputs supporting differential LVDS/HCSL/CML or single-ended modes.
• Integrated time stamping with nine UTS and two IUTS blocks for precise synchronization.
• Supports ITU-T G.8262, G.812, G.813, G.823, G.824, G.825, and G.8273.2 standards.

Applications

• 5G timing transport and high precision synchronization
• GPS, PTP (IEEE 1588), and SyncE jitter cleanup
• OTN, SDH, and macro/small cell base station clocking
• Stratum 2/3e/3 holdover and phase transient control
• JESD204B ADC/DAC clocking

Procurement Notes

Verify the REEL7 suffix indicates tape-and-reel packaging containing 750 units per reel. Confirm the specific revision matches the required design specifications. Check for moisture sensitivity level compliance before assembly. Ensure the ordering part number aligns with the manufacturer's current production status.

Selection Notes

Select this component for designs requiring dual independent DPLLs and extensive time-stamping capabilities. The 48-lead LFCSP package suits space-constrained layouts. Verify that the 1.8 V power supply requirement fits the system voltage rails. Consider the 500 MHz maximum output frequency against the target application needs.

Part Context

This part belongs to the AD9546 family of digitized clock synchronizers. The REEL7 suffix denotes the specific reel packaging format used for automated surface-mount assembly. It shares core functionality with the tray-packaged AD9546BCPZ variant.

Replacement Considerations

The AD9546BCPZ is a pin-compatible alternative available in tray packaging. No other direct substitutes are confirmed in the provided documentation.
