The ADF4030 provides for 10 bidirectional synchronized clock (BSYNC) channels and accepts a reference clock input (REFIN) signal as a frequency reference for generating an output clock on any BSYNC channels that are configured as an output. The hallmark feature of the ADF4030 is the ability to time align the clock edges of any one or more BSYNC channels to <5 ps (at the device pins) with respect to the BSYNC channel selected as the reference BSYNC channel.
The ADF4030 is well adapted for multiple connections with other ADF4030 devices for synchronizing clock signals in a system. Each BSYNC is bidirectional, allowing for reversing the direction of the clock signal to measure the propagation delay of the transmission medium. Round trip constructions that use replica paths are also supported. The bidirectional nature of the round trip delay measurement greatly reduces the error in determining the propagation delay through the BSYNC transmission medium as compared to using a replica path. This feature makes the ADF4030 capable to time align the clock edges of BSYNC channels across multiple ADF4030 devices, independent of the tree or cascade architecture in which the ADF4030 system is designed. The benefits of bidirectional clocking extend to devices other than the ADF4030 (assuming those devices support bidirectional clock exchanges).
The output divider block associated with each BYSNC channel has an optional pseudorandom binary sequence (PRBS) generator for Rev. 0 DOCUMENT FEEDBACK TECHNICAL SUPPORT FUNCTIONAL BLOCK DIAGRAM Figure 1.

The ADF4030 may be used as a standalone differential time-to-digital converter (TDC) to measure the difference in time between clocks arriving at the inputs.
The RMS jitter of one ADF4030 BSYNC clock is 4.3 ps typical.
The ADF4030 is available in a 48-lead, 7 mm × 7 mm, land grid array [LGA] package and operates over the −40°C to +105°C ambient temperature range.
Throughout the data sheet, the letter x is used to mean any integer. For example, in BSYNCx, x refers to any channel from Channel 0 to Channel 9.
