AD9531BCPZ-REEL7

Overview

The AD9531BCPZ-REEL7 is a three-channel clock generator and baseband clock distributor from Analog Devices, housed in an 88-lead LFCSP package. It integrates three PLL/VCO cores (PLL1, PLL2, PLL3) to provide 24 outputs with typical jitter performance of 0.462 ps rms. The device supports input frequencies ranging from 9.5 MHz to 260 MHz and generates output frequencies up to 400 MHz. It operates on 3.3 V and 1.8 V supplies within a temperature range of −40°C to +85°C.

Feature Summary

• Three fully integrated PLL cores: PLL1 (fractional/integer-N), PLL2 (integer-N), and PLL3 (integer-N).
• Low jitter performance with 0.462 ps rms typical absolute time jitter for PLL1 fractional mode.
• Supports HSTL, CMOS, and LVDS output formats across 24 channels.
• Includes loss of reference detection, lock detection, and automatic/manual output synchronization.

Applications

• Radio equipment controller clocking
• SONET, 10GE, and 10G FC protocol clock generation
• 40 Gbps/100 Gbps networking line cards
• High performance wireless transceivers

Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm the specific REEL7 packaging suffix matches system requirements. Check current availability status as supply conditions may vary. Ensure compliance with RoHS directives and environmental regulations relevant to the deployment region.

Selection Notes

Select this component when multiple low-jitter clock domains are required from a single source. Verify that the input frequency range (9.5 MHz to 260 MHz) aligns with the reference source. Ensure the target output frequencies do not exceed 400 MHz. Consider the 88-lead LFCSP thermal characteristics and PCB layout constraints during design.

Part Context

This part belongs to the AD9531 series of multi-output clock generators. It is designed for high-performance timing applications requiring precise phase relationships between multiple outputs. The device replaces discrete clock distribution solutions by integrating multiple PLLs and output drivers into a single compact package.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative Analog Devices clock generators based on channel count, jitter specifications, and package compatibility if replacement is necessary.

FAQ
