sysCLOCK Phase Locked Loops (PLLs)
The LA-MachXO1200 and LA-MachXO2280 provide PLL support. The source of the PLL input divider can come
from an external pin or from internal routing. There are four sources of feedback signals to the feedback divider:
from CLKINTFB (internal feedback port), from the global clock nets, from the output of the post scalar divider, and
from the routing (or from an external pin). There is a PLL_LOCK signal to indicate that the PLL has locked on to the
input clock signal. Figure 2-10 shows the sysCLOCK PLL diagram.
The setup and hold times of the device can be improved by programming a delay in the feedback or input path of
the PLL which will advance or delay the output clock with reference to the input clock. This delay can be either pro-
grammed during conguration or can be adjusted dynamically. In dynamic mode, the PLL may lose lock after
adjustment and not relock until the tLOCK parameter has been satised. Additionally, the phase and duty cycle block
allows the user to adjust the phase and duty cycle of the CLKOS output.
The sysCLOCK PLLs provide the ability to synthesize clock frequencies. Each PLL has four dividers associated
with it: input clock divider, feedback divider, post scalar divider, and secondary clock divider. The input clock divider
is used to divide the input clock signal, while the feedback divider is used to multiply the input clock signal. The post
scalar divider allows the VCO to operate at higher frequencies than the clock output, thereby increasing the fre-
quency range. The secondary divider is used to derive lower frequency outputs.
Figure 2-10. PLL Diagram
Figure 2-11 shows the available macros for the PLL. Table 2-5 provides signal description of the PLL Block.
