AD9540
PRODUCT OVERVIEW
The AD9540 is Analog Devices’ first dedicated clocking product
specifically designed to support the extremely stringent clock-
ing requirements of the highest performance data converters.
The device features high performance PLL 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. Informa-
tion is loaded into the AD9540 via a serial I/O port that has a
device write-speed of 25 Mb/s. 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.
