AD9525:  Low Jitter Clock Generator Eight LVPECL Outputs

Product Details

Product Status:Recommended for New Designs

The AD9525 is designed to support converter clock requirements for long-term evolution (LTE) and multicarrier GSM base station designs.

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 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 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.
