AD9540BCPZ (ANALOG DEVICES)
Clock Generator, 655 MHz, 1.8V supply, 1 Output, LFCSP-48
The AD9540BCPZ is a low-jitter Clock Generator 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 200MHz phase frequency detector and a digitally controlled charge pump current. The device also provides a low jitter, 655MHz CML-mode, PECL-compliant output driver with programmable slew rates. External VCO rates up to 2.7GHz are supported. Extremely fine tuning resolution (steps less than 2.33µHz) 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 25Mbps. The AD9540 frequency divider block can also be programmed to support a spread spectrum mode of operation.
