AD9544/PCBZ

AD9544/PCBZ is an evaluation board for AD9544 dual digital PLL and 1 PPS synchronizer. This board is a compact, easy-to-use platform for evaluating all features of the AD9544 dual digital PLL and 1 PPS synchronizer. The AD9544 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 IEEE 1588 Version 2, 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 output differential transmission line pairs use 50 ohm single ended characteristic impedance and are connected to standard edge launch SMA connectors. AD9544/PCBZ has a fully configurable power supply to allow user to evaluate AD9544 while being powered directly by a step down switching regulator or external LDOs.
