AD9517-0
1Provides multiple-output clock distribution with subpicosecond jitter performance and on-chip phase-locked loop (PLL) and voltage-controlled oscillator (VCO). The on-chip VCO is tuned over a frequency range of 2.55 GHz to 2.95 GHz. External VCCO/VCXOs up to 2.4 GHz can also be used.
The AD9517-0 has excellent low jitter and phase noise to greatly improve dataconverterand also benefit other applications with demanding phase noise and jitter.
The AD9517-0 has four LVPECL outputs in two pairs and four LVDS outputs in two pairs. Each LVDS output can be reconfigured as two CMOS outputs. The LVPECL output operates at 1.6 GHz, the LVDS output at 800 MHz, and the CMOS output at 250 MHz.
Each pair of outputs has a divider with programmable divider ratio and coarse delay (or phase). The LVPECL output is divided over a frequency division range of 1 to 32. The LVDS/CMOS output has a crossover range of up to 1024.
AD9517The -0 is available in a 48-pin LFCSP package and can operate from a single 3.3 V supply. An external VCO can be used when connecting a charge pump supply (VCP) to a 5V voltage, which requires a wider voltage range. The stand-alone LVPECL supply can be from 2.5 V to 3.3 V nominal.
The AD9517-0 is specified over the industrial temperature range of −40°C to +85°C.
