Product details

Clock generator with PLL and 1:10 fanout — what it covers

It accepts a single crystal input and delivers up to ten clock outputs in CMOS, LVDS, or LVPECL logic levels. The maximum output frequency is 156.25 MHz, making it a fit for mid-speed SERDES reference clocks, Ethernet PHY timing, or ADC/DAC sample clocks in communications and instrumentation equipment. The part operates from a 2.97 V to 3.63 V supply and is rated over the industrial temperature range of -40°C to 85°C.

Package and mounting — 40-LFCSP with exposed pad

Surface-mount only.

ADI lists the AD9571ACPZLVD as Active with ROHS3 compliance.

Frequently asked questions

Does AD9571ACPZLVD support 1:10 clock fanout with LVPECL outputs?

Yes. The part has a 1:10 input-to-output ratio and its outputs can be configured as LVPECL, LVDS, or CMOS. All ten outputs can be set to LVPECL simultaneously.

What is a direct replacement for AD9571ACPZLVD if it becomes obsolete?

ADI has not announced a successor or direct pin-compatible replacement. The AD9516-4BCPZ and AD9517-0ABCPZ are higher-frequency (2.95 GHz) clock generators with similar output types and a 1:14 or 1:12 fanout, but they differ in pinout, supply voltage (3.135 V), and differential input capability. A drop-in replacement is not available; a board redesign would be required.
