Data Sheet
AD9639
Rev. B | Page 27 of 36
Setting Bit 2 in the output mode register (Address 0x14) allows
the user to invert the digital outputs from their nominal state.
This is not to be confused with inverting the serial stream to an
LSB first mode. In default mode, as shown in Figure 2, the MSB
is first in the data output serial stream. However, this order can
be inverted so that the LSB is first in the data output serial stream.
There are eight digital output test pattern options available that
can be initiated through the SPI (see Table 12 for the output bit
sequencing options). This feature is useful when validating
receiver capture and timing. Some test patterns have two serial
sequential words and can be alternated in various ways, depending
on the test pattern selected. Note that some patterns do not
adhere to the data format select option. In addition, custom
user-defined test patterns can be assigned in the user pattern
registers (Address 0x19 through Address 0x20).
The PN sequence short pattern produces a pseudorandom bit
sequence that repeats itself every 29 1 (511) bits. A description
of the PN sequence short and how it is generated can be found
in Section 5.1 of the ITU-T O.150 (05/96) recommendation.
The only difference is that the starting value must be a specific
value instead of all 1s (see Table 11 for the initial values).
The PN sequence long pattern produces a pseudorandom bit
sequence that repeats itself every 223 1 (8,388,607) bits. A
description of the PN sequence long and how it is generated can
be found in Section 5.6 of the ITU-T O.150 (05/96) standard.
The only differences are that the starting value must be a specific
value instead of all 1s (see Table 11 for the initial values) and
that the AD9639 inverts the bit stream with relation to the ITU-T
standard.
