AD9575ARUZPEC

Overview

The AD9575ARUZPEC is a dual-output network clock generator from Analog Devices, featuring an integrated VCO/PLL core optimized for low jitter applications. It operates on a single 3.3 V supply within a 16-lead TSSOP package (4.4 mm × 5.0 mm). The device supports input crystal frequencies of 19.44 MHz, 25 MHz, or 25.78125 MHz. Pin-selectable divide ratios generate output frequencies including 33.33 MHz, 62.5 MHz, 100 MHz, 106.25 MHz, 125 MHz, 155.52 MHz, 156.25 MHz, 159.375 MHz, 161.13 MHz, and 312.5 MHz. Output formats include LVDS, LVPECL, and LVCMOS.

Feature Summary

• Integrated VCO/PLL core with no external loop filter required
• Low RMS jitter: 0.39 ps (12 kHz to 20 MHz) at 156.25 MHz
• Pin-programmable output frequency selection
• Supports LVDS, LVPECL, and LVCMOS output formats

Applications

• GbE/FC/SONET line cards, switches, and routers
• CPU/PCI-E applications
• Low jitter, low phase noise clock generation

Procurement Notes

Verify the ordering suffix PEC confirms the LVPECL output format, as distinct from the LVD variant. Confirm RoHS compliance status via official documentation. Ensure the 16-TSSOP package dimensions match the PCB footprint requirements. Check for any specific handling instructions regarding moisture sensitivity levels before assembly.

Selection Notes

Select this component when a highly integrated clock solution with minimal external components is required. The pin-selectable nature allows flexibility in generating standard network frequencies without software configuration. Consider the power supply current requirements (120 mA typical for LVPECL) during thermal design. Verify that the required output frequency is supported by the available crystal options and divider settings.

Part Context

The AD9575 belongs to the AD9575 series of network clock generators. The ARUZPEC designation indicates the -40°C to +85°C industrial temperature range, TSSOP-16 package, and LVPECL output configuration. It is part of Analog Devices' portfolio of integer-N PLL frequency synthesizers designed for high-performance telecommunications and networking equipment.

Replacement Considerations

The AD9575ARUZLVD serves as a direct functional substitute if LVDS outputs are preferred instead of LVPECL. Both share identical electrical characteristics, pinouts, and packaging, differing only in the output driver type.
