OUTPUT TEST

The AD9266 includes various output test options to place

predictable values on the outputs of the AD9266.

OUTPUT TEST MODES

The output test options are described in Table 16 at Address 0x0D.

When an output test mode is enabled, the analog section of the

ADC is disconnected from the digital back end blocks and the

test pattern is run through the output formatting block. Some of

the test patterns are subject to output formatting, and some are

not. The PN generators from the PN sequence tests can be reset

by setting Bit 4 or Bit 5 of Register 0x0D. These tests can be

performed with or without an analog signal (if present, the analog

signal is ignored), but they do require an encode clock. For more

information, see the AN-877 Application Note, Interfacing to

High Speed ADCs via SPI.
