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 CMLmode, PECL-compliant output driver with programmable slew rates. External VCO rates up to 2.7 GHz are supported.
