The AD9573 is a PCI-Express clock generator IC with a fully integrated VCO/PLL core, low jitter, and low phase noise. It is suitable for line cards, switches, routers, CPU/PCIe applications, and other applications with demanding phase noise and jitter requirements.
The AD9573 provides a highly integrated dual‑output clock generator for PCI‑Express applications. It includes an on‑chip PLL, loop filter, and output buffers, requiring only a 25 MHz external crystal and a 3.3 V supply.
Key features include 0.54 ps rms jitter (12 kHz‑20 MHz), low phase‑noise outputs, and a compact 16‑lead TSSOP package. The device operates from –40 °C to +85 °C and is RoHS compliant.
