DLL
DQS phase-shift circuitry uses a DLL to dynamically measure the clock period
required by the DQS/CQ and CQn pin. The DLL, in turn, uses a frequency reference
to dynamically generate control signals for the delay chains in each of the DQS/CQ
and CQn pins, allowing it to compensate for PVT variations. The DQS delay settings
are Gray-coded to reduce jitter when the DLL updates the settings. The phase-shift
circuitry requires a maximum of 1280 clock cycles to lock and calculate the correct
input clock period when the DLL is in low jitter mode. Otherwise, only 256 clock
cycles are required. Do not send data during these clock cycles because there is no
guarantee it can be properly captured. As the settings from the DLL may not be stable
until this lock period has elapsed, you should be aware that anything using these
settings (including the leveling delay system) may be unstable during this period.
Use the DQS phase-shift circuitry for any memory interfaces that are less than
100 MHz. The DQS signal is shifted by 2.5 ns. Even if the DQS signal is not shifted
exactly to the middle of the DQ valid window, the I/O element should still be able to
capture the data in low frequency applications where a large amount of timing
margin is available.
There are four DLLs in a Stratix III device, located in each corner of the device. These
DLLs support a maximum of four unique frequencies, with each DLL running at one
frequency. Each DLL can have two outputs with different phase offsets, which allow
one Stratix III device to have eight different DLL phase shift settings.
