Lattice Semiconductor
Table 2-4 provides signal descriptions of the PLL block.
sysMEM Embedded Block RAM Memory
The MachXO2-640/U and larger devices contain sysMEM Embedded Block RAMs (EBRs). The EBR consists of a
9-Kbit RAM, with dedicated input and output registers. This memory can be used for a wide variety of purposes
including data buffering, PROM for the soft processor and FIFO.
sysMEM Memory Block
The sysMEM block can implement single port, dual port, pseudo dual port, or FIFO memories. Each block can be
used in a variety of depths and widths as shown in Table 2-5.

Input clock to PLL
Feedback clock
Select which output is affected by Dynamic Phase adjustment ports
Dynamic Phase adjustment direction
Dynamic Phase step – toggle shifts VCO phase adjust by one step.
Primary PLL output clock (with phase shift adjustment)
Secondary PLL output clock (with phase shift adjust)
Secondary PLL output clock2 (with phase shift adjust)
Secondary PLL output clock3 (with phase shift adjust)
PLL LOCK, asynchronous signal. Active high indicates PLL is locked to input and feed-
back signals.
Dynamic Phase source – ports or
Standby signal to power down the PLL
PLL reset without resetting the M-divider. Active high reset.
PLL reset - includes resetting the M-divider. Active high reset.
Reset for CLKOS2 output divider only. Active high reset.
