AD9549ABCPZ Description

Short technical summary and product information.

The AD9549ABCPZ is a dual input network clock generator/synchronizer from Analog Devices Inc., designed for synchronization in networking and telecommunications systems. It incorporates a PLL with a programmable digital loop filter offering bandwidth from <1 Hz to ~100 kHz. The device accepts two reference inputs with loss of reference indicators and supports automatic holdover and smooth phase transitions.

 

Key specifications include an input frequency range of 8 kHz to 750 MHz. Output options include differential HSTL clock up to 750 MHz and single-ended CMOS up to 150 MHz. The device operates from a 1.71V to 3.465V supply and is rated for an industrial temperature range of -40°C to 85°C.

 

The AD9549ABCPZ is housed in a surface-mount 64-VFQFN exposed pad package (64-LFCSP-VQ, 9x9 mm). It is suitable for network synchronization, SONET/SDH clock generation up to OC-192, Stratum 3/3E reference clocks, wireless base station controllers, and cable infrastructure applications.
