Introduction

The AD9575ARUZLVD is a highly integrated dual-output clock generator, featuring an on-chip PLL core optimized for network timing. The integer N frequency division PLL design is based on ADI's mature high-performance and low-jitter frequency synthesizer series, which can achieve high performance of line cards. Other applications with strict requirements for phase noise and jitter can also benefit from this device.

The AD9575ARUZLVD PLL section consists of a low-noise frequency and phase detector (PFD), a precision charge pump, a low-phase noise voltage-controlled oscillator (VCO), and a pin-optional feedback and output frequency divider. By connecting an external crystal oscillator, the AD9575ARUZLVD can lock the commonly used network output frequencies to the input reference. The output frequency division ratio and feedback frequency division ratio can be programmed through pins according to the required output rate. The AD9575ARUZLVD does not require an external loop filter, thus saving valuable design time and circuit board space.

The AD9575ARUZLVD is available in a 16-pin, 4.4mm × 5.0mm TSSOP package and can be powered by a single 3.3V supply. The temperature range is from -40 °C to +85°C.
