Analog Devices AD9518-1 Manuals

This product is a low phase noise, phase-locked loop (PLL) 6-output clock generator with integrated 2.5 GHz VCO. It has 1 differential or 2 single-ended reference inputs, and can accept LVPECL, LVDS or CMOS reference signals, up to 250 MHz. Digital or analog lock detect can be selected. It has 3 pairs of 1.6 GHz LVPECL outputs. Each output pair shares a 1:32 divider with coarse phase delay. Additive output jitter is 225 fs rms. Channel-to-channel skew paired outputs are less than 10 ps. All outputs are automatically synchronized on power-up. Manual output synchronization is available. This product is suitable for low jitter, low phase noise clock distributors, digital baseband and wireless communication systems.
