Figure 2-31. DQS Local Bus
Polarity Control Logic
In a typical DDR memory interface design, the phase relationship between the incoming delayed DQS strobe and
the internal system clock (during the READ cycle) is unknown. The LatticeXP2 family contains dedicated circuits to
transfer data between these domains. To prevent set-up and hold violations, at the domain transfer between DQS
(delayed) and the system clock, a clock polarity selector is used. This changes the edge on which the data is regis-
tered in the synchronizing registers in the input register block and requires evaluation at the start of each READ
cycle for the correct clock polarity.
Prior to the READ operation in DDR memories, DQS is in tristate (pulled by termination). The DDR memory device
drives DQS low at the start of the preamble state. A dedicated circuit detects this transition. This signal is used to
control the polarity of the clock to the synchronizing registers.
*DQSXFERDEL shifts ECLK1 by 90% and is not associated with a particular PIO.
