1 All test mode options except PN sequence short and PN sequence long can support 12-bit to 16-bit word lengths to verify data capture to the receiver.
When the SPI is used, the DCO phase can be adjusted in 60°
increments relative to the data edge. This enables the user to
refine system timing margins if required. The default DCO+
and DCO timing, as shown in Figure 2, is 90° relative to the
output data edge.
A 12-bit serial stream can also be initiated from the SPI. This
allows the user to implement and test compatibility to lower
resolution systems. When changing the resolution to a 12-bit
serial stream, the data stream is shortened. See Figure 3 for the
12-bit example. However, in the default option with the serial
output number of bits at 16, the data stream stuffs two 0s at the
end of the 14-bit serial data.
In default mode, as shown in Figure 2, the MSB is first in the
data output serial stream. This can be inverted so that the LSB is
first in the data output serial stream by using the SPI.
There are 12 digital output test pattern options available that
can be initiated through the SPI. This is a useful feature when
validating receiver capture and timing. Refer to Table 11 for the
output bit sequencing options available. Some test patterns have
two serial sequential words and can be alternated in various
ways, depending on the test pattern chosen. 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 0x19, 0x1A, 0x1B, and 0x1C register addresses.
The PN sequence short pattern produces a pseudorandom bit
sequence that repeats itself every 29 1 or 511 bits. A
description of the PN sequence and how it is generated can be
found in Section 5.1 of the ITU-T 0.150 (05/96) standard. The
seed value is all 1s (see Table 12 for the initial values). The
output is a parallel representation of the serial PN9 sequence in
MSB-first format. The first output word is the first 14 bits of the
PN9 sequence in MSB aligned form.
The PN sequence long pattern produces a pseudorandom bit
sequence that repeats itself every 223 1 or 8,388,607 bits. A
description of the PN sequence and how it is generated can be
found in Section 5.6 of the ITU-T 0.150 (05/96) standard. The
seed value is all 1s (see Table 12 for the initial values) and the
AD9253 inverts the bit stream with relation to the ITU standard.
The output is a parallel representation of the serial PN23 sequence
in MSB-first format. The first output word is the first 14 bits of the
PN23 sequence in MSB aligned form
