AD9516-5BCPZ

14路输出时钟发生器 14-Output Clock Generator

Product Details

The AD9516-51 provides a multi-output clock distribution function with subpicosecond jitter performance, along with an on-chip PLL that can be used with an external VCO/VCXO of up to 2.4 GHz.

The AD9516-5 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 AD9516-5 features six LVPECL outputs in three 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.

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 AD9516-5 is available in a 64-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 5.5 V. A separate LVPECL power supply can be from 2.375 V to 3.6 V nominal.

The AD9516-5 is specified for operation over the industrial range of −40°C to +85°C.

For applications requiring an integrated EEPROM, or needing additional outputs, the AD9520-5 and AD9522-5 are available.
