altpll (Phase-Locked Loop) Megafunction



Parameterized phase-locked loop (PLL) megafunction. The altpll megafunction enables PLL circuitry. The phase-locked loop is used to synthesize a clock signal that is based on a reference clock. The altpll megafunction can reduce clock delay and skew, and can be used to generate internal clocks that operate at frequencies that are multiples of the frequency of the system clock. The altpll megafunction can also improve setup and hold times. The Cyclone and Stratix PLLs have the ability to simultaneously multiply and divide the reference clock, provide an arbitrary phase shift, provide an external clock, and synchronize via an external feedback input.

NOTE The Cyclone PLL uses a subset of the ports and parameters of the altpll megafunction. Altera® recommends instantiating this function as described in Using the MegaWizard® Plug-In Manager.

Port Descriptions:

INPUT PORTS

Port Name Required Description Comments
inclk[] Yes The clock port that drives the PLL. The PRIMARY_CLOCK parameter specifies which clock the PLL uses. You can switch clocks with the clkswitch port. You can use the active_clock output port to specify if inclk1 or inclk2 port is used.
fbin No The external feedback input port for the PLL. The fbin port must be specified if the OPERATION_MODE parameter is set to EXTERNAL_FEEDBACK mode. To complete the feedback loop, there must be a board-level connection between the fbin pin and the external clock output pin of the PLL.
pllena No The PLL enable signal. When the pllena port is high, the PLL drives out a signal. When the pllena port is low, the PLL does not drive out a signal and goes out of lock. The pllena port acts as a combined enable and reset pin. When the pin is reasserted, the PLL has to re-lock. The device contains only one enable pin. If a PLL on the device uses the enable pin, all PLLs on the device must use the same enable pin.
clkswitch No Switches between input clock ports. The clkswitch port can only be connected if both the inclk0 and inclk1 ports are connected.
areset No Resets all counters to initial values. This port resets all counters, including the GATE_LOCK_COUNTER parameter, to their initial values. The PLL can be programmed after the device has been configured.
pfdena No Enables the phase frequency detector (PFD). Allows the VCO pin to continue to operate. When the PFD is disabled, the PLL continues to operate regardless of the input clock. Because the output clock frequency does not change for some time, you can use pfdena port as a shutdown or cleanup function when a reliable input clock is no longer available.
clkena[] No Enables the clk[] ports to the PLL.  
extclkena[] No Enables the extclk[] ports to the PLL.  
scanclk No Clock signal for the serial scan chain.  
scanaclr No Asynchronous clear for the real-time programming scan chain or the serial scan chain.  
scandata No Contains the data for the serial scan chain.  

OUTPUT PORTS

Port Name Required Description Comments
clk[] No The clock output of the PLL.  
extclk[] No The clock output that feeds the dedicated pins.  
clkbad[] No Specifies which signal goes high. If the inclk0 stops toggling, the clkbad0 is high. If the inclk1 stops toggling, the clkbad1 is high.
activeclock No Specifies which input clock port is used. When the activeclock port is high, clk0 port is used. When the activeclock port is low, clk1 port is used.
clkloss No Specifies when the clock switchover circuit initiates. The clock switchover circuit initiates when the primary reference clock is not toggling correctly or if you specify with the clkswitch input port.

Parameter Descriptions:

Parameter Type Required Comments
OPERATION_MODE String Yes Specifies the operation of the PLL. Values are "EXTERNAL_FEEDBACK", "NO_COMPENSATION", "NORMAL", and "ZERO_DELAY_BUFFER". If omitted, the default is NORMAL. In NORMAL mode, the PLL compensates for the delay of the internal clock network used by the clock output specified in the COMPENSATE_CLOCK parameter. If the PLL is also used to drive the internal clock network, a corresponding phase shift of that network results. In ZERO_DELAY_BUFFER mode, the PLL must feed an external clock output pin and compensate for the delay introduced by that pin. The signal observed on the pin will be synchronized to the input clock. If the PLL is also used to drive the internal clock network, a corresponding phase shift of that network results. In EXTERNAL_FEEDBACK mode, the fbin port must be connected to an input pin and there must be a board-level connection between this input pin and an external clock output pin, which is specified with FEEDBACK_SOURCE parameter. The fbin port is aligned with the input clock. In NO_COMPENSATION mode, the PLL does not align a clock to the input, which leads to better jitter performance.
PLL_TYPE String No Specifies the type of PLL to instantiate. Values are "AUTO", "ENHANCED", and "FAST". If omitted, the default is AUTO.
COMPENSATE_CLOCK String No Specifies the output clock port which should be compensated. If the OPERATION_MODE parameter is specified to NORMAL, values are "CLK[]", "GCLK[]", "LCLK[]", or "LVDSCLK[]". If the OPERATION_MODE parameter is specified to ZERO_DELAY_BUFFER, value is "EXTCLK[]". This clock cannot offset with respect to the reference clock, and this relationship is preserved closely even upon temperature and frequency changes. In NORMAL mode, default is CLK0. In ZERO_DELAY_BUFFER mode, default is EXTCLK0. For example, if CLK0 is specified when the OPERATION_MODE parameter is specified to NORMAL, the Compiler's compensation selection in terms of GCLK[], LCLK[], or LVDSCLK[] is based on CLK0 routing.
SCAN_CHAIN String No Specifies the length of the scan chain. Values are "LONG" or "SHORT". If omitted, the default is LONG. If "LONG" is specified, the scan chain length is 10 counters. If "SHORT" is specified, the scan chain length is 6 counters.
PRIMARY_CLOCK String No Specifies the primary reference clock of the PLL. Values are "INCLK0" or "INCLK1". If omitted, the default is INCLK0. You can use the clock switch scheme to switch between clocks; however, you can only switch back to the primary clock with a user initiated switch.
INCLK0_INPUT_FREQUENCY Integer Yes Specifies the input frequency for the inclk0 clock. The Compiler uses the frequency of clk0 port to calculate the PLL parameters, but also analyzes and reports the phase shifts for the clk1 port.
INCLK1_INPUT_FREQUENCY Integer No Specifies the input frequency for the inclk1 clock. The Compiler uses the frequency of clk0 port to calculate the PLL parameters, but also analyzes and reports the phase shifts for the clk1 port.

SWITCH_OVER_ON_LOSSCLK String No Specifies whether the loss of lock condition should initiate a clock switch over. Values are "ON" or "OFF". If omitted, the value is OFF.
