AD9518-1 * provides multi-channel output clock allocation function, with sub-picosecond jitter performance, and integrates a phase-locked loop (PLL) and a voltage controlled oscillator (VCO) on the chip. The tuning frequency range of on-chip VCO is 2.30 GHz to 2.65 GHz. External VCO/VCXO up to 2.4 GHz can also be used AD9518-1 has excellent low jitter and phase noise characteristics, which can greatly improve the performance of data converters and is also beneficial for other applications with strict phase noise and jitter requirements. AD9518-1 has six LVPECL outputs (divided into three groups). The operating frequency of LVPECL output can reach 1.6 GHz

Each pair of outputs has a frequency divider, and its division ratio and coarse tuning delay (or phase) can be set. The frequency division range of LVPECL output is 1 to 32 The AD9518-1 offers a 48 pin LFCSP package that can be powered by a single 3.3V power supply. When using an external VCO, a wider voltage range is required, which can be achieved by aligning the charge pump power supply (VCP) with a 5.5 V voltage
