Product Details

The AD9518-2The AD9518-21 provides a multi-output clock distribution function with subpicosecond jitter performance, along with an on-chip PLL and VCO. The on-chip VCO tunes from 2.05 GHz to 2.33 GHz. Optionally, an external VCO/VCXO of up to 2.4 GHz can be used.

The AD9518-2 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 AD9518-2 features six LVPECL outputs (in three pairs). The LVPECL outputs operate to 1.6 GHz.

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 AD9517 are similar to the AD9518 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 AD9518-2 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 AD9518-2 is specified for operation over the industrial range of −40°C to +85°C.

Applications
