The AD9540 is Analog Devices’ first dedicated clockingproduct specifically designed to support the extremely stringentclocking requirements of the highest performance dataconverters. The device features high performance PLL (phase-lockedloop) circuitry, including a flexible 200 MHz phasefrequency detector and a digitally controlled charge pumpcurrent. The device also provides a low jitter, 655 MHz CML-mode,PECL-compliant output driver with programmable slewrates. External VCO rates up to 2.7 GHz are supported.
Extremely fine tuning resolution (steps less than 2.33 µHz) isanother feature supported by this device. Information is loadedinto the AD9540 via a serial I/O port that has a device writespeed of 25 Mbps. The AD9540 frequency divider block canalso be programmed to support a spread spectrum mode ofoperation.
The AD9540 is specified to operate over the extendedautomotive range of −40°C to +85°C.
