Architecture
LatticeECP/EC Family Data Sheet
grammed during configuration or can be adjusted dynamically. In dynamic mode, the PLL may lose lock after
adjustment and not relock until the tLOCK parameter has been satisfied. 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 2-12 shows the available macros for the PLL. Table 2-5 provides signal description of the PLL Block.
