GENERAL DESCRIPTION

The AD9525 is designed to support converter clock requirements

for long-term evolution (LTE) and multicarrier GSM base station

designs.

The AD9525 offers a dedicated output that can be used to provide

a programmable signal for resetting or synchronizing a data

converter. The output signal is activated by a SPI write.

The AD9525 provides a low power, multioutput, clock distribution

function with low jitter performance, along with an on-chip PLL

that can be used with an external VCO or VCXO. The VCO input

and eight LVPECL outputs can operate up to a frequency of

3.6 GHz. All outputs share a common divider that can provide

a division of 1 to 6.

The AD9525 is available in a 48-lead LFCSP and can be operated

from a single 3.3 V supply. The external VCXO or VCO can

have an operating voltage of up to 5.5 V.

The AD9525 operates over the extended industrial temperature

range of −40°C to +85°C.
