AD9525: Low Jitter Clock Generator with Eight LVPECL Outputs Data Sheet (Rev. A)10/11/20121296 kB
Features and Benefits
- Integrated ultra low noise synthesizer
- 8 differential 3.6 GHz LVPECL outputs and 1 LVPECL or 2 CMOS SYNC Outputs
- 2 differential reference inputs and 1 single-ended reference inputs
Product DetailsThe 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.Applications

Evaluation Kits (1)
The AD9525 evaluation board is a compact, easy to use platform for evaluating all features of the AD9525. Two versions of the evaluation board are available: one with a prepopulated external VCO and loop filter (AD9525/PCBZ-VCO) and one with no VCO/VCXO and no loop filter (AD9525/PCBZ). The user guide focuses on the AD9525/PCBZ-VCO, which already has a VCO and loop filter on board. 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 also offers a dedicated output that can be used to provide a programmable signal for resetting or synchronizing a data converter. For more information about the device, see the AD9525 data sheet. The user guide should be used in conjunction with the AD9525 data sheet and the software documentation available at www.analog.com/clocks.
