2.7 Clocks

This section describes the daughterboard clocks. It contains the following subsections.

• Overview of clocks

• Daughterboard programmable clock generators on page 2-27

• Test chip PLLs and clock divider logic on page 2-30

• External clocks on page 2-32.

2.7.1 Overview of clocks

The daughterboard sends clocks to, and receives clocks from, the motherboard and generates

local clocks that are imported into the Cortex-A15_A7 MPCore test chip. Additional PLLs

inside the test chip provide phase-shifted and frequency-multiplied versions of these imported

clocks as Figure 2-10 on page 2-26 shows.

Figure 2-9 on page 2-25 shows a functional overview of the CoreTile Express A15×2 A7×3

daughterboard clocks and their connections to the motherboard and a LogicTile Express FPGA

daughterboard.
