AD9523BCPZ

The AD9523BCPZ from Analog Devices is a low-power, multi-output clock distribution IC designed for high-performance applications. It features a dual PLL architecture with an integrated VCO tuning from 3.6 GHz to 4.0 GHz, providing a flexible clock generation solution.

This device offers up to 14 differential or 29 LVCMOS outputs, configurable to LVPECL, LVDS, HSTL, and LVCMOS standards. Key electrical specifications include an output frequency range up to 1 GHz, input-to-output edge timing under 150 ps, and output-to-output skew below 50 ps. It also boasts low absolute output jitter of less than 200 fs at 122.88 MHz and a distribution phase noise floor of -160 dBc/Hz.

The AD9523BCPZ supports zero-delay operation and features automatic synchronization on power-up. It includes redundant reference inputs with automatic and manual switchover modes, along with loss of reference detection and holdover capabilities. The device is controlled via an SPI- and I2C-compatible serial port and stores configuration settings in nonvolatile EEPROM.

Packaged in a 72-LFCSP-VQ (10x10) or 72-VFQFN Exposed Pad, CSP, this clock generator is designed for surface mounting. It operates within a temperature range of -40°C to 85°C and requires a supply voltage between 1.71V and 3.465V. Its primary applications include clocking for Ethernet, Fibre Channel, and SONET/SDH protocols, as well as wireless infrastructure and medical instrumentation.
