AD9531 Datasheet 3-Channel Clock Generator

Manufacturer: Analog Devices

Overview: Data Sheet 3-Channel Clock Generator, 24 Outputs AD9531.

General Description

The AD9531 provides a multioutput clock generator function and three on-chip phase-locked loop (PLL) cores with SPI programmable output frequencies and formats.

PLL1 provides two reference inputs and 10 outputs and includes four user selectable loop configurations.

The PLL has a fully integrated loop filter requiring on
