OUTPUT TEST

The AD9608 includes various output test options to place

predictable values on the outputs of theAD9608.

OUTPUT TEST MODES

The output test options are described in Table 18 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.
