AD9516-0BCPZ

ANALOG DEVICES  AD9516-0BCPZ  芯片, 时钟发生器, 2.95GHZ, LFCSP-64

GENERAL DESCRIPTION

The AD9516-01 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 2.55 GHz to 2.95 GHz. Optionally, an external VCO/VCXO of up to 2.4 GHz may be used.

The AD9516-0 emphasizes low jitter and phase noise to maximize data converter performance, and can benefit other applications with demanding phase noise and jitter requirements.

The AD9516-0 features six LVPECL outputs in three pairs; four LVDS outputs in two pairs; and eight CMOS outputs two per LVDS output. The LVPECL outputs operate to 1.6 GHz, the LVDS outputs operate to 800 MHz, and the CMOS outputs operate to 250 MHz
