AD9515BCPZ-REEL7

Clock Buffers, Drivers Overview

The AD9515BCPZ-REEL7 is a two-output clock distribution IC designed for low jitter and phase noise performance. It accepts a differential clock input up to 1.6 GHz and provides one LVPECL output operating to 1.6 GHz and one configurable LVDS or CMOS output operating to 800 MHz or 250 MHz, respectively. Each output includes a programmable integer divider with a range of 1 to 32. The device features a delay block on the LVDS/CMOS output for coarse and fine timing adjustments. Configuration is managed via 11 logic pins (S0–S10) using a 4-level voltage scheme without requiring an external controller.

Clock Buffers, Drivers Feature Summary

• Two independent outputs: 1.6 GHz LVPECL and 800 MHz LVDS/250 MHz CMOS
• Programmable integer dividers (÷1 to ÷32) on both channels
• Additive output jitter of 225 fs rms (LVPECL), 300 fs rms (LVDS), and 290 fs rms (CMOS)
• Delay block with selectable full-scale values (1.5 ns, 5 ns, 10 ns) and 16-step fine adjustment

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 REEL7 suffix indicates tape and reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the supply voltage matches the specified 3.3 V nominal requirement for proper operation within the -40°C to +85°C temperature range.

Clock Buffers, Drivers Selection Notes

Select this component when sub-picosecond jitter performance is critical for data converter applications. The LVDS/CMOS output mode must be chosen based on the target interface requirements, as it supports either differential LVDS or single-ended CMOS signaling. Verify that the required divide ratios fall within the 1 to 32 integer range and that the input clock slew rate meets the 1 V/ns minimum specification.

Clock Buffers, Drivers Part Context

The AD9515BCPZ-REEL7 belongs to the Analog Devices AD9515 series of clock drivers and distributors. It is housed in a 32-lead LFCSP package and operates from a single 3.3 V supply. The device is part of a family designed to maximize data converter performance by minimizing added phase noise and jitter compared to standard buffer solutions.
