AD9511BCPZ

Clock Buffers, Drivers Overview

The AD9511BCPZ is a clock distribution IC featuring an integrated PLL core, dividers, and delay adjust capabilities. It provides five independent outputs: three LVPECL channels operating up to 1.2 GHz with 225 fs rms additive jitter, and two selectable LVDS (800 MHz) or CMOS (250 MHz) channels with 275 fs rms additive jitter. The device accepts reference inputs up to 250 MHz and supports dual 1.6 GHz differential clock inputs. It operates on a single 3.3 V supply within a -40°C to +85°C temperature range, housed in a 48-lead LFCSP package.

Clock Buffers, Drivers Feature Summary

• Integrated low phase noise PLL core with programmable charge pump and separate VCPS supply
• Five independent outputs: three 1.2 GHz LVPECL and two 800 MHz LVDS/250 MHz CMOS
• Programmable integer dividers (1 to 32) with phase select for coarse output-to-output delay adjustment
• Fine delay adjust block on one LVDS/CMOS output providing up to 10 ns of programmable delay

Clock Buffers, Drivers Applications

• Low jitter, low phase noise clock distribution systems
• Clocking high-speed ADCs, DACs, DDSs, DDCs, DUCs, and MxFEs
• High-performance wireless transceivers
• Broadband infrastructure equipment

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and shipping configuration. Ensure compatibility with system voltage requirements, as the charge pump supply (VCPS) may require extension up to 5.5 V for external VCO operation. Confirm moisture sensitivity handling procedures are followed during assembly.

Clock Buffers, Drivers Selection Notes

Select this component when subpicosecond jitter encoding is required for data converter applications. The AD9511 supports frequencies up to 1.6 GHz on inputs and 1.2 GHz on LVPECL outputs. Designers must account for the serial control port interface for register configuration and ensure proper termination for LVPECL (50 Ω to VS − 2 V) and LVDS (100 Ω differential) outputs to maintain signal integrity.

Clock Buffers, Drivers Part Context

The AD9511 belongs to Analog Devices' family of clock distribution and timing solutions. It is designed to maximize data converter performance by minimizing phase noise and jitter. The device integrates both frequency synthesis via its PLL and flexible clock distribution, making it suitable for complex multi-clock architectures in telecommunications and instrumentation.
