Analog Devices Inc. AD9518-1ABCPZ

Description
The AD9518-1 is a multi-output clock generator with subpicosecond jitter performance. It features an on-chip PLL and VCO that tunes from 2.30 GHz to 2.65 GHz. Optionally, an external VCO/VCXO of up to 2.4 GHz can be used.
The AD9518-1 emphasizes low jitter and phase noise to maximize data converter performance. It can also benefit other applications with demanding phase noise and jitter requirements.
The AD9518-1 features six LVPECL outputs (in three pairs). The LVPECL outputs operate to 1.6 GHz. Each pair of outputs has dividers that allow both the divider ratio and coarse delay (or phase) to be set. The range of division for the LVPECL outputs is 1 to 32.
The AD9518-1 is available in a 48-lead LFCSP and can be operated from a single 3.3 V supply. An external VCO, which requires an extended voltage range, can be accommodated by connecting the charge pump supply (VCP) to 5 V. A separate LVPECL power supply can be from 2.5 V to 3.3 V (nominal).
The AD9518-1 is specified for operation over the industrial range of -40°C to 85°C.
