AD9515BCPZ

Clock Buffers, Drivers Overview

The AD9515BCPZ is a two-output clock distribution integrated circuit designed for low jitter and phase noise applications. It accepts a differential clock input up to 1.6 GHz and provides two independent outputs: an LVPECL output operating up to 1.6 GHz and a secondary output configurable as either LVDS (up to 800 MHz) or CMOS (up to 250 MHz). Each output includes a programmable divider with integer division ratios from 1 to 32. The device operates on a single 3.3 V supply within a temperature range of -40°C to +85°C and is housed in a 32-lead LFCSP package.

Clock Buffers, Drivers Feature Summary

• Dual independent outputs: LVPECL (1.6 GHz max) and LVDS/CMOS (800 MHz/250 MHz max)
• Programmable divide-by counters ranging from 1 to 32 for each output
• Additive output jitter of 225 fs rms for LVPECL, 300 fs rms for LVDS, and 290 fs rms for CMOS
• Hardware configuration via 11 logic pins (S0-S10) without external controller requirement

Clock Buffers, Drivers Applications

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

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging type. The base part number may be available in tray or reel formats. Confirm that the required voltage supply is 3.3 V and that the PCB layout accommodates the exposed thermal pad of the 32-LFCSP-VQ package for proper grounding and heat dissipation.

Clock Buffers, Drivers Selection Notes

Select this component when subpicosecond jitter performance is critical for data converter applications. Ensure the input clock signal meets the required slew rate of 1 V/ns to maintain specified jitter and phase noise characteristics. Verify that the system power supply transitions from 2.2 V to 3.1 V within 35 ms during power-on to ensure proper output synchronization.

Clock Buffers, Drivers Part Context

The AD9515 belongs to Analog Devices' family of clock distribution ICs focused on maximizing data converter performance. It serves as a buffer and divider solution for systems requiring precise timing relationships between multiple clock domains. The device eliminates the need for complex serial programming interfaces by utilizing direct hardware logic pin configuration.
