Timing Characteristics of 4:1 DDR 3-State Controller Serialization
The second word IJKLMNOP is sampled into the master and slave OSERDES from the D1–
D6 and D3–D4 inputs, respectively.
Clock Event 4
Between Clock Events 3 and 4, the entire word ABCDEFGH is transmitted serially on OQ,
a total of eight bits transmitted in one CLKDIV cycle.
The data bit I appears at OQ four CLK cycles after IJKLMNOP is sampled into the
OSERDES. This latency is consistent with the
OSERDES latency of four CLK cycles.
The operation of a 3-State Controller is illustrated in
case shown in a bidirectional system where the IOB must be frequently 3-stated.
