12-Output Clock Generator with Integrated 2.2 GHz VCO
The AD9517-2 emphasizes low jitter and phase noise to maximize data converter performance, and it can benefit other applications with demanding phase noise and jitter requirements.
The AD9517-2 features 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 outputs operate to 1.6 GHz, the LVDS outputs operate to 800 MHz, and the CMOS outputs operate to 250 MHz.
For applications that require additional outputs, a crystal reference input, zero-delay, or EEPROM for automatic configuration at startup, the AD9520 and AD9522 are available. In addition, the AD9516 and AD9518 are similar to the AD9517 but have a different combination of outputs.
Each pair of outputs has dividers that allow both the divide ratio and coarse delay (or phase) to be set. The range of division for the LVPECL outputs is 1 to 32. The LVDS/CMOS outputs allow a range of divisions up to a maximum of 1024.
The AD9517-2 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 AD9517-2 is specified for operation over the industrial range of −40°C to +85°C.
