Подробнее о продукте

The AD9545 evaluation board is a compact, easy-to-use platform for evaluating all features of the AD9545 dual digital PLL and 1 pps synchronizer. The AD9545 provides high-precision, multi-output clock generator functions, along with two on-chip jitter cleaning digital PLL cores. PLL0 and PLL1 are optimized for high performance synchronous clocking applications such as GPS, IEEE1588v2, Synchronous Ethernet, OTN, and next generation wireless baseband protocols. The PLLs are fully configurable via serial port control as well as configurable via an external EEPROM for power on ready configurations.


The AD9545 can output up to 5 differential clock signals, plus two single-ended clocks driven by a mix of two high performance digital PLLs, plue two high-precision NCOs (numerically controlled oscillators). 12 total outputs and 4 reference inputs are accessible on the evaluation board.


The output differential transmission line pairs use 50Ω single ended characteristic impedance and are connected to standard edge launch SMA connectors. The AD9545/PCBZ has a fully configurable power supply to allow the user to evaluate the AD9545 while being powered directly by a step down switching regulator or external LDOs. The AD9545 evaluation board uses RoHS-compliant FR-4 material. For convenience, detailed information from the AD9545 data sheet has been included here. Use this user guide in conjunction with the datasheet that has been provided by ADI.
