AD9543

Quad Input, 10-Output, Dual DPLL/IEEE 1588 Synchronizer and Jitter Cleaner

Manufactured by:

Product Details

The AD9543 supports existing and emerging ITU standards for the delivery of frequency, phase, and time of day over service provider packet networks.

The 10 clock outputs of the AD9543 are synchronized to any one of up to four input references. The digital phase-locked loops (DPLLs) reduce timing jitter associated with the external references. The digitally controlled loop and holdover circuitry continuously generate a low jitter output signal, even when all reference inputs fail.

The AD9543 is available in a 48-lead LFCSP (7 mm × 7 mm) package and operates over the −40°C to +85°C temperature range.

Note that throughout this data sheet, multifunction pins, such as SDO/M5, are referred to either by the entire pin name or by a single function of the pin, for example, M5, when only that function is relevant.

Product Details

The AD9543 evaluation board is a compact, easy-to-use platform for evaluating all features of the AD9543 dual digital PLL and 1 PPS synchronizer. The AD9543 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 AD9543 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 AD9543 has a fully configurable power supply to allow the user to evaluate the AD9543 while being powered directly by a step down switching regulator or external LDOs. The AD9543 evaluation board uses RoHS-compliant FR-4 material. For convenience, detailed information from the AD9543 data sheet has been included here. Use this user guide in conjunction with the datasheet that has been provided by ADI.
