HDMP-1014 (Rx) Timing
Figure 7 is the Rx timing diagram
when the internal PLL is locked to
the incoming serial data. The
BCLK’s frequency is the same as
the input data rate. The size of
the input data frame can be either
20 bits or 24 bits, depending on
the setting of M20SEL.
Independent of the frame size,
STBROUT’s falling edge is aligned

to the data frame’s boundary,
while the rising edge is in the
center of the data frame.
The synchronous outputs, D00-
D19, LINKRDY*, DAV*, CAV*,
FF, ERROR, and FLAG, are
updated for every data frame,
with a delay of t
edge of STRBOUT. There is a
latency delay of two frames from
D-FIELD
d1
after the falling
C-FIELD
the input of the serial data frame
to the update of the synchronous
outputs.
The state machine outputs,
STAT0, and STAT1, appear with
the falling edge of STRBOUT after
a delay of td2. These outputs are
updated once every 128 frames.
