Clock generator with PLL and 1:10 fanout — what it covers
The AD9571ACPZLVD from Analog Devices is a clock generator IC that integrates a PLL, a crystal oscillator interface, and a 1:10 fanout distribution buffer. 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
Housed in a 40-lead LFCSP-WQ (6x6 mm) with an exposed pad for thermal dissipation. Surface-mount only. The exposed pad must be soldered to a ground plane for rated thermal performance; the datasheet's recommended land pattern should be followed closely to avoid solder voids under the pad.
Lifecycle and sourcing
ADI lists the AD9571ACPZLVD as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect. The part is available through independent distribution and is sourced to order against an RFQ; current pricing and lead time are confirmed at quote time.
