Data to Data Clock Forbidden Area

Phase Relationship Between Data Ready and CW_IN Clock Input
There is a forbidden time range in the phase relation between Data Ready and the CW_IN mas-
ter clock. This forbidden zone occurs when active rising edges of CW_IN and Data Ready do not
comply with the setup and hold times (see Figure 5-4 on page 22). Within this forbidden zone,
the data is stored in the second bank of master latches at the time when the first outputs of slave
latches switch (acquisition of next incoming data). Within this critical time range of 600 ps, data
pattern throughput transmission errors may occur.
To satisfy setup and hold times, the phase of the Data Ready input (D_CK_T to D_CK_F) can
be adjusted by choosing one of the 16 DSP clock shift positions (assuming that the DSP provid-
ing the data and Data Ready signals to the MUXDAC is clocked by the MUXDAC DSP clock’s
output signal).
Figure 5-4.
Data Ready (D_CK) to CW_IN Master Clock Timing
If the D_CK clock edge occurs within the forbidden zone, there is an ambiguity on the data to be
transferred from the first to the second bank of latch (data N or data N + 1).
