AD9525BCPZ-REEL7

Overview

The AD9525BCPZ-REEL7 is a low jitter clock generator featuring eight LVPECL outputs and an integrated ultralow noise synthesizer. It operates with a single 3.3 V supply and supports frequencies up to 3.6 GHz on the VCO input and outputs. The device includes an on-chip PLL compatible with external VCOs or VCXOs, two differential reference inputs, and one single-ended reference input. All outputs share a common divider providing division ratios from 1 to 6. It is housed in a 48-lead LFCSP package and functions within an extended industrial temperature range of −40°C to +85°C.

Feature Summary

• Eight differential 3.6 GHz LVPECL outputs plus one LVPECL SYNC output
• Integrated ultralow noise synthesizer with on-chip PLL for external VCO/VCXO
• Two differential reference inputs (REFA, REFB) and one single-ended reference input (REFC)
• Common output divider supporting division ratios of 1 to 6

Applications

• LTE and multicarrier GSM base stations
• Clocking high speed ADCs and DACs
• ATE and high performance instrumentation
• 40/100 Gb/sec OTN line side clocking
• Cable/DOCSIS CMTS clocking

Procurement Notes

Verify the REEL7 suffix indicates tape-and-reel packaging when sourcing. Confirm the specific grade matches system requirements as the datasheet lists multiple variants. Check for RoHS compliance status via manufacturer documentation. Ensure ESD precautions are observed during handling due to the LFCSP package sensitivity.

Selection Notes

Select this component for designs requiring low phase noise distribution across multiple channels. Ensure the external VCO or VCXO voltage does not exceed 5.5 V. Verify that the SPI control interface timing meets the 31 MHz maximum clock rate requirement. Account for power dissipation up to 1.25 W under typical operation conditions.

Part Context

This part belongs to the AD9525 family of clock generators designed for converter clocking applications. It serves as a multioutput distribution solution with integrated frequency synthesis capabilities. The BCPZ designation identifies the 48-lead LFCSP package variant suitable for surface mount assembly.
