PRODUCT OVERVIEW

The AD9540 is Analog Devices’ first dedicated clocking

product specifically designed to support the extremely stringent

clocking requirements of the highest performance data

converters. The device features high performance PLL (phase-

locked loop) circuitry, including a flexible 200 MHz phase

frequency detector and a digitally controlled charge pump

current. The device also provides a low jitter, 655 MHz CML-

mode, PECL-compliant output driver with programmable slew

rates. External VCO rates up to 2.7 GHz are supported.

Extremely fine tuning resolution (steps less than 2.33 μHz) is

another feature supported by this device. Information is loaded

into the AD9540 via a serial I/O port that has a device write

speed of 25 Mbps. The AD9540 frequency divider block can

also be programmed to support a spread spectrum mode of

operation.

The AD9540 is specified to operate over the extended

automotive range of −40°C to +85°C.
