AD9517-4ABCPZ

The AD9517-4ABCPZ from Analog Devices is a versatile clock generator and fanout distribution IC designed for applications requiring low jitter and phase noise. It features an on-chip VCO that tunes from 1.45 GHz to 1.80 GHz, with options for external VCO/VCXO up to 2.4 GHz.

This device provides multiple output types, including two pairs of 1.6 GHz LVPECL outputs and two pairs of 800 MHz LVDS outputs. Each LVDS output can be reconfigured as two 250 MHz CMOS outputs. The AD9517-4ABCPZ supports various reference inputs (LVPECL, LVDS, CMOS) up to 250 MHz and includes features like automatic reference switchover and holdover modes.

Packaged in a 48-lead LFCSP, the AD9517-4ABCPZ is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C, and it operates from a 3.135V to 3.465V supply. This clock generator is ideal for demanding clock distribution needs in networking, high-speed data converters, and instrumentation.

Key electrical specifications include additive output jitter of 225 fs rms for LVPECL outputs and 275 fs rms for LVDS outputs. Channel-to-channel skew for paired LVPECL outputs is less than 10 ps. The device also offers programmable delays and selectable digital or analog lock detect.
