Description
Address and command output register
clock. The addr_cmd_clk clock
frequency must be the same as the system
clock, clk , and the write clock,
write_clk , frequencies.
In addition, when there is a separate
address and command clock phase, no
timing paths related to this clock should be
cut, to ensure that any paths using a
separate clock for address and command
are timing analysed.
dqs_delay_ctrl[]
6
Input
Delay bus for DLL to shift DQS inputs. DQS
mode only.
non_dqs_capture_clk
1
Input
Optional clock that captures read data and
clocks read data logic. Non-DQS mode
only.
reset_clk_n
1
Input
Reset input for logic on the system clock
domain. The reset_clk_n can be
asserted asynchronously but must be
deasserted synchronous to the rising edge
of the system clock.
reset_addr_cmd_clk_n 1
Input
Reset input for logic on the address and
command clock domain. The
reset_addr_cmd_clk_n can be
asserted asynchronously but must be
deasserted synchronous to the rising edge
of the address and command clock.
