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.
